  • Is it possible to use array_shift() in PHP and get the key?

    - by alex
    I have a list of files in an array where the filename is the key and the value is the last modified date in seconds. They are sorted from oldest to newest. The files are glob()'d in, and then sorted this way using asort($fileNameToLastModified, SORT_NUMERIC); I use array_shift() to get the oldest file. Unfortunately, it seems to be giving me the value, and there doesn't seem to be a way to get the key. Would the only way to do that be something like this? $keys = array_keys($fileNameToLastModified); $oldest = array_shift($keys); array_shift($fileNameToLastModified); // to manually chop the first array member off too. Or is there a built in? Thanks

  • How do I dynamically name objects in Java?

    - by hatboysam
    Let's say I needed to make a series of String[] objects. I know that if i wanted to make a string array called "test" to hold 3 Strings I could do String[] test = new String[3]; But let's say I needed to make a series of these arrays and I wanted them to be named, 1,2, 3, 4, 5... etc. For however many I needed and I didn't know how many I'd need. How do I achieve a similar effect to this: for (int k=0; k=5; k++){ String[] k = new String[3]; } Which would created 5 string arrays named 1 through 5. Basically I want to be able to create array objects with a name detemined by some other function. Why can't I seem to do this? Am I just being stupid?

  • Storing unique values into an array and comparing against a loop - PHP

    - by Aphex22
    I'm writing a PHP report which is designed to be exported purely as a CSV file, using commma delimiters. There are three columns relating to product_id, these three columns are as follows: SKU Parent / Child Parent SKU 12345 parent 12345 12345_1 child 12345 12345_2 child 12345 12345_3 child 12345 12345_4 child 12345 18099 parent 18099 18099_1 child 18099 Here's a link to the full CSV file: http://i.imgur.com/XELufRd.png At the moment the code looks like this: $sql = "select * from product WHERE on_amazon = 'on' AND active = 'on'"; $result = mysql_query($sql) or die ( mysql_error() );?> <? // set headers echo " Type, SKU, Parent / Child, Parent SKU, Product name, Manufacturer name, Gender, Product_description, Product price, Discount price, Quantity, Category, Photo 1, Photo 2, Photo 3, Photo 4, Photo 5, Photo 6, Photo 7, Photo 8, Color id, Color name, Size name <br> "; // load all stock while ($line = mysql_fetch_assoc($result) ) { ?> <?php // Loop through each possible size variation to see whether any of the quantity column has stock > 0 $con_size = array (35,355,36,37,375,38,385,39,395,40,405,41,415,42,425,43,435,44,445,45,455,46,465,47,475,48,485); $arrlength=count($con_size); for($x=0;$x<$arrlength;$x++) { // check if size is available if($line['quantity_c_size_'.$con_size[$x].'_chain'] > 0 ) { ?> <? echo 'Shoes'; ?>, <?=$line['product_id']?>, , , <?=$line['title']?>, <? $brand = $line['jys_brand']; echo ucfirst($brand); ?>, <? $gender = $line['category']; if ($gender == 'Mens') { echo 'H'; } else{ echo 'F'; } ?>, <?=preg_replace('/[^\da-z]/i', ' ', $line['amazon_desc']) ?>, <?=$line['price']?>, <?=$line['price']?>, <?=$line['quantity_c_size_'.$con_size[$x].'_chain']?>, <? $category = $line['style1']; switch ($category) { case "ankle-boots": echo "10013"; break; case "knee-high-boots": echo "10011"; break; case "high-heel-boots": echo "10033"; break; case "low-heel-boots": echo "10014"; break; case "wedge-boots": echo "10014"; break; case "western-boots": echo "10032"; break; case "flat-shoes": echo "10034"; break; case "high-heel-shoes": echo "10039"; break; case "low-heel-shoes": echo "10039"; break; case "wedge-shoes": echo "10035"; break; case "ballerina-shoes": echo "10008"; break; case "boat-shoes": echo "10018"; break; case "loafer-shoes": echo "10037"; break; case "work-shoes": echo "10039"; break; case "flat-sandals": echo "10041"; break; case "low-heel-sandals": echo "10042"; break; case "high-heel-sandals": echo "10042"; break; case "wedge-sandals": echo "10042"; break; case "mule-sandals": echo "10038"; break; case "mary-jane-shoes": echo "10039"; break; case "sports-shoes": echo "10026"; break; case "court-shoes": echo "10035"; break; case "peep-toe-shoes": echo "10035"; break; case "flat-boots": echo "10609"; break; case "mid-calf-boots": echo "10014"; break; case "trainer-shoes": echo "10009"; break; case "wellington-boots": echo "10012"; break; case "lace-up-boots": echo "10609"; break; case "chelsea-and-jodphur-boots": echo "10609"; break; case "desert-and-chukka-boots": echo "10032"; break; case "lace-up-shoes": echo "10034"; break; case "slip-on-shoes": echo "10043"; break; case "gibson-and-derby-shoes": echo "10039"; break; case "oxford-shoes": echo "10039"; break; case "brogue-shoes": echo "10039"; break; case "winter-boots": echo "10021"; break; case "slipper-shoes": echo "10016"; break; case "mid-heel-shoes": echo "10039"; break; case "sandals-and-beach-shoes": echo "10044"; break; case "mid-heel-sandals": echo "10042"; break; case "mid-heel-boots": echo "10014"; break; default: echo ""; } ?>, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_1.jpg, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_2.jpg, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_3.jpg, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_4.jpg, , , , , <? $colour = preg_replace('/[^\da-z]/i', ' ', $line['colour']); if( preg_match( '/white.*/i', $colour)) { echo '1'; } elseif( preg_match( '/yellow.*/i', $colour)) { echo '4'; } elseif( preg_match( '/orange.*/i', $colour)) { echo '7'; } elseif( preg_match( '/red.*/i', $colour)) { echo '8'; } elseif( preg_match( '/pink.*/i', $colour)) { echo '13'; } elseif( preg_match( '/purple.*/i', $colour)) { echo '15'; } elseif( preg_match( '/blue.*/i', $colour)) { echo '19'; } elseif( preg_match( '/green.*/i', $colour)) { echo '25'; } elseif( preg_match( '/brown.*/i', $colour)) { echo '28'; } elseif( preg_match( '/grey.*/i', $colour)) { echo '35'; } elseif( preg_match( '/black.*/i', $colour)) { echo '38'; } elseif( preg_match( '/gold.*/i', $colour)) { echo '41'; } elseif( preg_match( '/silver.*/i', $colour)) { echo '46'; } elseif( preg_match( '/multi.*/i', $colour)) { echo '594'; } elseif( preg_match( '/beige.*/i', $colour)) { echo '6887'; } elseif( preg_match( '/nude.*/i', $colour)) { echo '6887'; } else { echo '534'; } ?>, <?=$line['colour']?>, <?=$con_size[$x]?> <br> <? // finish checking if size is available } } ?> So at the moment this is simply echoing out the product_ID into the SKU column. The code would need to enter the product_id into an array and check whether it is unique. If the product_id is unique to the array, then the product_id is echoed out unaltered, and parent is echoed out to the 'Parent/Child' column and then the product_id is repeated to the 'Parent SKU' column. However, if the array is checked and the product_id already exists in the array, then the product_id is echoed out to the 'SKU' column with a suffix i.e. _1. Then child is echoed to the 'Parent / Child' column and the original parent product_id echoed to the 'Parent SKU' column. HOWEVER - the same SKU cannot be repeated with the same suffix i.e. 12345_1, 12345_1 - so presumably there would be to be another array for the suffixed SKUs to be checked against. If anybody could help, it would be great. Thanks --- UPDATE ANSWER --- I managed to solved this myself and thought I would share my solution for future reference. /* * Array to collect product_ids and check whether unique. * If unique product_id becomes parent SKU * If not product_id becomes child of previous parent and suffixed with _1, _2 etc... */ if (!in_array($line['product_id'], $SKU)) { $SKU[] = $line['product_id']; $parent = $line['product_id']; $a = 0; ?> <? echo 'Shoes'; ?>, <? echo $parent; ?>, <? echo "Parent"; ?>, <? echo $parent; ?>, <? } else { $child = $line['product_id'] . "_" . $a; ?> <? echo 'Shoes'; ?>, <? echo $child; ?>, <? echo "Child"; ?>, <? echo $child; <? // increment suffix value for child SKU $a++; ?>

  • Objective C Object Functioning & Passing Arrays

    - by Patrick
    I apologise if this has been asked before but I can't find the info I need. Basically I want a UITableView to be populated using info from a server, similar to the SeismicXML example. I have the parser as a separate object, is it correct to alloc, init an instance of that parser & then tell RootViewController to make it's table data source a copy of the parser's array. I can't include code because I haven't written anything yet, I'm just trying to get the design right before I start. Perhaps something like: xmlParser = [[XMLParser alloc] init]; [xmlParser getXMLData]; // Assuming xmlParser stores results in an array called returnedArray self.tableDataSource = xmlParser.returnedArray Is this the best way of doing it?

  • Value isnt being saved in the strings

    - by Raptrex
    I'm trying to make a class where I put a key and value into the put method which puts the key in the k string array and value into the v string array, however it is not being saved in the array when I do get or display. For example: put(dan,30) get(dan) returns null display returns null null 10 times. Anyone know whats wrong? public class Memory { final int INITIAL_CAPACITY = 10; String[] k = new String[INITIAL_CAPACITY]; String[] v = new String[INITIAL_CAPACITY]; int count = 0; public Memory() { count = 0; } public int size() { return count; } public void put(String key, String value) { int a = 0; boolean found = false; for (int i = 0; i < k.length; i++) { //System.out.println("key is " + key.equals(k[i])); if (key.equalsIgnoreCase(k[i])) { v[i] = value; found = true; } if (found) break; a++; } //System.out.println(a == k.length); if (a == k.length); { k[count] = key; v[count] = value; //System.out.println(k[count] + " " + v[count]); count++; //System.out.println(count); } } public String get(String key) { String output = "a"; for(int i = 0; i < k.length; i++) { if(!key.equalsIgnoreCase(k[i])) { output = null; } else { output = v[i]; return output; } } return output; } public void clear() { for (int i = 0; i < k.length; i++) { k[i] = null; v[i] = null; } count = 0; } public void display() { for (int i = 0; i < k.length; i++) { System.out.println(k[i] + " " + v[i]); } } }

  • PHP FTP Upload thousands of files

    - by user275074
    Hi, I've written a small FTP class which I used to move files from a local server to a remote server. It does this by checking an array of local files with an array of files on the remote server. If the file exists on the remote server, it won't bother uploading it. The script works fine for small amounts of files, but I've noticed that the local server can have as many as 3000+ image files to transfer, this seems to cause the script to flop and only transfer a 100 or so. How can I modify the script to handle potentially thousands of image transfer files?

  • Find inner arrays in nested arrays

    - by 50ndr33
    I have a nested array in PHP: array ( '0' => "+5x", '1' => array ( '0' => "+", '1' => "(", '2' => "+3", '3' => array ( '0' => "+", '1' => "(", '2' => array ( // I want to find this one. '0' => "+", '1' => "(", '2' => "+5", '3' => "-3", '4' => ")" ), '3' => "-3", '4' => ")" ), '4' => ")" ) ); I need to process the innermost arrays here, the one with the comment: "I want to find this one." Is there a function for that? I have thought about doing (written as an idea, not as correct PHP): foreach ($array as $id => $value) { if ($value is array) { $name = $id; foreach ($array[$id] as $id_2 => $value_2) { if ($value_2 is array) { $name .= "." . $id_2; foreach ($array[$id][$id_2] as $id_3 => $value_3) { if ($value_3 is array) { $name .= "." . $id_3; foreach ($array[$id][$id_2][$id_3] as $id_4 => $value_4) { if ($value_4 is array) { $name .= "." . $id_4; foreach [and so it goes on]; } else { $listOfInnerArrays[] = $name; break; } } } else { $listOfInnerArrays[] = $name; break; } } } else { $listOfInnerArrays[] = $name; break; } } } } So what it does is it makes $name the current key in the array. If the value is an array, it goes into it with foreach and adds "." and the id of the array. So we would in the example array end up with: array ( '0' => "1.3.2", ) Then I can process those values to access the innner arrays. The problem is that the array that I'm trying to find the inner arrays of is dynamic and made of a user input. (It splits an input string where it finds + or -, and puts it in a separate nested array if it contains brackets. So if the user types a lot of brackets, there will be a lot of nested arrays.) Therefore I need to make this pattern go for 20 times down, and still it will only catch 20 nested arrays no matter what. Is there a function for that, again? Or is there a way to make it do this without my long code? Maybe make a loop make the necessary number of the foreach pattern and run it through eval()? Long answer to J. Bruni: <?php $liste = array ( '0' => "+5x", '1' => array ( '0' => "+", '1' => "(", '2' => "+3", '3' => array ( '0' => "+", '1' => "(", '2' => array ( '0' => "+", '1' => "(", '2' => "+5", '3' => "-3", '4' => ")" ), '3' => "-3", '4' => ")" ), '4' => ")" ) ); function find_deepest( $item, $key ) { echo "0"; if ( !is_array( $item ) ) return false; foreach( $item as $sub_item ) { if ( is_array( $sub_item ) ) return false; } echo "1"; print_r( $item ); return true; } array_walk_recursive( $liste, 'find_deepest' ); echo "<pre>"; print_r($liste); ?> I wrote echo 0 and 1 to see what the script did, and here is the output: 00000000000000 Array ( [0] => +5x [1] => Array ( [0] => + [1] => ( [2] => +3 [3] => Array ( [0] => + [1] => ( [2] => Array ( [0] => + [1] => ( [2] => +5 [3] => -3 [4] => ) ) [3] => -3 [4] => ) ) [4] => ) ) )

  • MODX parse error function implode (is it me or modx?)

    - by Ian
    Hi, I cannot for the life of me figure this out, maybe someone can help. Using MODX a form takes user criteria to create a filter and return a list of documents. The form is one text field and a few checkboxes. If both text field and checkbox data is posted, the function works fine; if just the checkbox data is posted the function works fine; but if just the text field data is posted, modx gives me the following error: Error: implode() [function.implode]: Invalid arguments passed. I've tested this outside of modx with flat files and it all works fine leading me to assume a bug exists within modx. But I'm not convinced. Here's my code: <?php $order = array('price ASC'); //default sort order if(!empty($_POST['tour_finder_duration'])){ //duration submitted $days = htmlentities($_POST['tour_finder_duration']); //clean up post array_unshift($order,"duration DESC"); //add duration sort before default $filter[] = 'duration,'.$days.',4'; //add duration to filter[] (field,criterion,mode) $criteria[] = 'Number of days: <strong>'.$days.'</strong>'; //displayed on results page } if(!empty($_POST['tour_finder_dests'])){ //destination/s submitted $dests = $_POST['tour_finder_dests']; foreach($dests as $value){ //iterate through dests array $filter[] = 'searchDests,'.htmlentities($value).',7'; //add dests to filter[] $params['docid'] = $value; $params['field'] = 'pagetitle'; $pagetitle = $modx->runSnippet('GetField',$params); $dests_array[] = '<a href="[~'.$value.'~]" title="Read more about '.$pagetitle.'" class="tourdestlink">'.$pagetitle.'</a>'; } $dests_array = implode(', ',$dests_array); $criteria[] = 'Destinations: '.$dests_array; //displayed on results page } if(is_array($filter)){ $filter = implode('|',$filter);//pipe-separated string } if(is_array($order)){ $order = implode(',',$order);//comma-separated string } if(is_array($criteria)){ $criteria = implode('<br />',$criteria); } echo '<br />Order: '.$order.'<br /> Filter: '.$filter.'<br /> Criteria: '.$criteria; //next: extract docs using $filter and $order, display user's criteria using $criteria... ?> The echo statement is displayed above the MODX error message and the $filter array is correctly imploded. Any help will save my computer from flying out the window. Thanks

  • How to simplify my code... 2D NSArray in Objective C...?

    - by Tattat
    self.myArray = [NSArray arrayWithObjects: [NSArray arrayWithObjects: [self d], [self generateMySecretObject],nil], [NSArray arrayWithObjects: [self generateMySecretObject], [self generateMySecretObject],nil],nil]; for (int k=0; k<[self.myArray count]; k++) { for(int s = 0; s<[[self.myArray objectAtIndex:k] count]; s++){ [[[self.myArray objectAtIndex:k] objectAtIndex:s] setAttribute:[self generateSecertAttribute]]; } } As you can see this is a simple 2*2 array, but it takes me lots of code to assign the NSArray in very first place, because I found that the NSArray can't assign the size at very beginning. Also, I want to set attribute one by one. I can't think of if my array change to 10*10. How long it could be. So, I hope you guys can give me some suggestions on shorten the code, and more readable. thz

  • direct access to vector elements similar to arrays

    - by mixm
    hi. im currently creating a tile based game, where elements of the games are placed in four different vectors (since there are multiple game objects with different properties, hence stored in different vectors). these game elements themselves contain x and y coordinates similar to how they are stored in a two dimensional array. i was wondering if there was a way to access these vector elements similar to two dimensional array access (currently i am implementing an for loop to cycle the elements while comparing its coordinates). this kinda sucks when i need to refresh my display at every game cycle (since the large number of comparisons and loops). im implementing this in java btw.

  • PHP scope question

    - by Dan
    Hi, I'm trying to look through an array of records (staff members), in this loop, I call a function which returns another array of records (appointments for each staff member). foreach($staffmembers as $staffmember) { $staffmember['appointments'] = get_staffmember_appointments_for_day($staffmember); // print_r($staffmember['appointments'] works fine } This is working OK, however, later on in the script, I need to loop through the records again, this time making use of the appointment arrays, however they are unavailable. foreach ($staffmembers as $staffmember) { //do some other stuff //print_r($staffmember['appointments'] no longer does anything } Normally, I would perform the function from the first loop, within the second, however this loop is already nested within two others, which would cause the same sql query to be run 168 times. Can anyone suggest a workaround? Any advice would be greatly appreciated. Thanks

  • second sorting with php usort

    - by bluedaniel
    So Ive got a pretty big array of data and need to sort them by two criteria. There is variable $data['important'] and $data['basic']. They are simple numbers and I am using uasort to sort $data firstly by important and then by basic. So Important | Basic 10 | 8 9 | 9 9 | 7 7 | 9 The usort function is a simple public function sort_by_important($a, $b) { if ($a[important] > $b[important]) { return -1; } elseif ($b[important] > $a[important]) { return 1; } else { return 0; } } How can I re-sort the array to the second variable and keep the Important ordering? Thanks everyone. EDIT How about adding a third sorting option after this even? So Important Basic Less

Of course di reason is for reusing $getLimit closure with another regular expression like $smsPattern. Thanks.

I am new to numpy and matplotlib and am essentially trying to run this by adapting the examples I can find. Here's how I built my arrays from a file that has them stored: XY_File = open ('XY_Output.txt', 'r') XY = XY_File.readlines() XY_File.close() Xf=[] Yf=[] for line in XY: Xf.append(float(line.split('\t')[0])) Yf.append(float(line.split('\t')[1])) x=array(Xf) y=array(Yf) Is there a problem with my arrays? This same code worked when put into this example but I'm not too sure. Why am I getting this MemoryError and how can I fix this?

  • How to use php variables (arrays) in mysql select statements?

    - by davidconn
    Hi everybody, How do you use a php variable (array) inside a mysql select statement? I am designing an auction site and currently working on a page that lets people view a list of all the current bids for an item. I want to display 3 columns: amountbid - the amount each bidder has bid for the item (held in tblbid) bidderid - the id of each bidder who has bid (found in tbluser) total_positivity_feedback - how many users have left positive feedback for the bidder (calculated from tblfeedback) To find the 'amount' and the 'bidderid' columns i pass the essayid URL parameter from the previous page. This works fine. Despite this, i can't display the total_positivity_feedback column for the various users who have made each bid. My mysql query looks like this: select tblbid.bidderid, tblbid.amount, (select count(tblfeedback.feedbackid) from tblfeedback WHERE tblfeedback.writerid = "ARRAY VARIABLE GOES HERE") AS total_positivity_feedback FROM tblbid WHERE tblbid.essayid = $essayid_bids I assume that the only way to accomplish this is to make the variable contain the bidderid's of those people who bid for that particular essay? I can't seem to work out how to do this tho?!? Many thanks for your help

  • Php, in_array with no exactly match

    - by John Smith
    I want to do the following: $a = array(); $a[] = array(1,2); $a[] = array(2,5); $a[] = array(3,4); var_dump (in_array(array(2,5), $a)); this returns OK, as it expected, but if the source array is not fully matched: $a = array(); $a[] = array(1,2, 'f' => array()); $a[] = array(2,5, 'f' => array()); $a[] = array(3,4, 'f' => array()); var_dump (in_array(array(2,5), $a)); it returns false. Is there a way to do it with the built-in way, or I have to code it?

  • Unable to install Windows 2008R2 x64 on HP ProLiant ML 150 G6 with Smart Array B110i

    - by lrosa
    I am installing Windows 2008 R2 x64 (Microsoft OEM version) on a ProLint ML 150 with Smart Array B110i controller. I load the B110i drivers from a USB thumbdrive, Windows Setup can create, delete and format correctly the partitions on the raidset, but when I exit the disk manager to start setup, Windows says that he cannot find a primary partition to install Windows. The EasySetup disk provided with the system does not support Windows 2008 R2 x64 Microsoft OEM. I downloaded the latest version of EasySetup from HP website, but does not support Windows 2008 R2 x64 Microsoft OEM. Any suggestion?

  • Access Western Digital My Book World II RAID array on my Ubuntu Linux

    - by ZeDalaye
    Hi, My WD My Book World II (Blue Rings) NAS has overheated, I think the motherboard is dead. I extracted the disks and plugged them in my desktop PC running Ubuntu Linux. The disks seems to be alive, they are spinning and the BIOS recognize them but Ubuntu is not able to boot as soon as these drives are plugged in. I got an initramfs shell after few minutes telling explaining that the root disk is not available. I suspect that one of my WD drives took the precedence on the system ? Considering that Ubuntu is able to boot and can see my Western Digital disks... is it possible to access the RAID 0 array ? How ? Many thanks for your help, regards, -- Pierre Yager
