• Search for values in nested array

  - by dardub

  I have an array as follows array(2) { ["operator"] => array(2) { ["qty"] => int(2) ["id"] => int(251) } ["accessory209"] => array(2) { ["qty"] => int(1) ["id"] => int(209) } ["accessory211"] => array(2) { ["qty"] => int(1) ["id"] => int(211) } } I'm trying to find a way to verify an id value exists within the array and return bool. I'm trying to figure out a quick way that doesn't require creating a loop. Using the in_array function did not work, and I also read that it is quite slow. In the php manual someone recommended using flip_array() and then isset(), but I can't get it to work for a 2-d array. doing something like if($array['accessory']['id'] == 211) would also work for me, but I need to match all keys containing accessory -- not sure how to do that Anyways, I'm spinning in circles, and could use some help. This seems like it should be easy. Thanks.

• get the array with html array path

  - by antpaw

  hey, i have this path name from an input element interesse[angebote][flurfuerderfahrzeuge] as a string in my php var. now i need convert it somehow (with regex or explode()) so it looks like this: $_POST['interesse']['angebote']['flurfuerderfahrzeuge'] and the use eval() to get the value. But I'm sure there must be a much easier way do this. Any ideas? Thanks!

• This for array colllision function doesn't work with anything but first object in array

  - by Zee Bashew

  For some reason, this simple simple loop is totally broken. (characterSheet is my character Class, it's just a movieClip with some extra functionality) (hitBox, is basically a square movieclip) Anyway: every time hitBox make contact with a characterSheet in a different order than they were created: Nothing happens. The program only seems to be listening to collisions that are made with o2[0]. As soon as another hitBox is created, it pushes the last one out of o2[0] and the last one becomes totally useless. What's super weird is that I can hit characterSheets in any order I like.... public function collisions(o1:Array, o2:Array) { if((o1.lenght>=0)&&(o2.length>=0)){ for (var i = 0; i < o1.length; i++) { var ob1 = o1[i]; for (var f = 0; f < o1.length; f++) { var ob2 = o2[f]; if (ob1 is characterSheet) { if (ob2.hitTestObject(ob1)) { var right:Boolean = true; if (ob1.x < hitBox(ob2).origin.x) right = false; characterSheet(ob1).specialDamage(hitBox(ob2).damageType, hitBox(ob2).damage, right); }}}}}} Also it might be somewhat helpful to see the function for creating a new hitBox public function SpawnHitBox(targeted, following, atype, xoff, yoff, ... args) { var newHitBox = new hitBox(targeted, following, atype, xoff, yoff, args); badCollisionObjects.push(newHitBox); arraydictionary[newHitBox] = badCollisionObjects; addChild(newHitBox); }

• Find key of parent in array / PHP

  - by 106691756905536410593

  Perhaps someone can help me out with this one: I'm using a basic search function to find an array deep within an array. The problem is, once that array is found, I'd also like to return it's parent key. Is there a PHP function that can determine the parent key of an array? Below is an example of the Search Function... Ideally I'd like to return the array that is found, as well as it's parent key. function search($array, $key, $value){ $results = array(); if (is_array($array)){ if ($array[$key] == $value){ $results[] = $array; } foreach ($array as $subarray){ $results = array_merge($results, search($subarray, $key, $value)); } } return $results; }

• php multidimensional array problem

  - by ntan

  Hi to all, i am trying to setup a multidimensional array but my problem is that i can not get the right order from incoming data. Explain $x[1][11]=11; $x[1]=1; var_dump($x); In the above code i get only x[1]. To right would be $x[1]=1; $x[1][11]=11; var_dump($x); But in my case i can dot ensure that x[1] will come first, and x[1][11] will come after. Is there any way that i can use the first example and get right the array. Keep in mind that the array depth is large. Thats

• SQL SERVER – SSAS – Multidimensional Space Terms and Explanation

  - by pinaldave

  I was presenting on SQL Server session at one of the Tech Ed On Road event in India. I was asked very interesting question during ‘Stump the Speaker‘ session. I am sharing the same with all of you over here. Question: Can you tell me in simple words what is dimension, member and other terms of multidimensional space? There is no simple example for it. This is extreme fundamental question if you know Analysis Service. Those who have no exposure to the same and have not yet started on this subject, may find it a bit difficult. I really liked his question so I decided to answer him there as well blog about the same over here. Answer: Here are the most important terms of multidimensional space – dimension, member, value, attribute and size. Dimension – It describes the point of interests for analysis. Member – It is one of the point of interests in the dimension. Value – It uniquely describes the member. Attribute – It is collection of multiple members. Size – It is total numbers for any dimension. Let us understand this further detail taking example of any space. I am going to take example of distance as a space in our example. Dimension – Distance is a dimension for us. Member – Kilometer – We can measure distance in Kilometer. Value – 4 – We can measure distance in the kilometer unit and the value of the unit can be 4. Attribute – Kilometer, Miles, Meter – The complete set of members is called attribute. Size – 100 KM – The maximum size decided for the dimension is called size. The same example can be also defined by using time space. Here is the example using time space. Dimension – Time Member – Date Value – 25 Attribute – 1, 2, 3…31 Size – 31 I hope it is clear enough that what are various multidimensional space and its terms.

• In .NET, What Is Fastest Way to Initialize Multi-Dimensional Array to Non-Default Value

  - by AMissico

  How do I initialize a multi-dimensional array of a primitive type as fast as possible? I am stuck with using multi-dimensional arrays. My problem is performance. The following routine initializes a 100x100 array in approx. 500 ticks. Removing the int.MaxValue initialization results in approx. 180 ticks just for the looping. Approximately 100 ticks to create the array without looping and without initializing to int.MaxValue. Routines similiar to this are called a few tens-of-thousands to several million times. I am open to suggestions on how to optimize this non-default initialization of an array. One idea I had is to use a smaller primitive type when available. For instance, using byte instead of int, saves 100 ticks. I would be happy with this, but I am hoping that I don't have to change the primitive data type. public int[,] CreateArray(Size size) { int[,] array = new int[size.Width, size.Height]; for (int x = 0; x < size.Width; x++) { for (int y = 0; y < size.Height; y++) { array[x, y] = int.MaxValue; } } return array; }

• Copy a multi-dimentional array by Value (not by reference) in PHP.

  - by Simon R

  Language: PHP I have a form which asks users for their educational details, course details and technical details. When the form is submitted the page goes to a different page to run processes on the information and save parts to a database. HOWEVER(!) I then need to return the page back to the original page, where having access to the original post information is needed. I thought it would be simple to copy (by value) the multi-dimensional (md) $_POST array to $_SESSION['post'] session_start(); $_SESSION['post'] = $_POST; However this only appears to place the top level of the array into $_SESSION['post'] not doing anything with the children/sub-arrays. An abbreviated form of the md $_POST array is as follows: Array ( [formid] = 2 [edu] = Array ( ['id'] = Array ( [1] = new_1 [2] = new_2 ) ['nameOfInstitution'] = Array ( [1] = 1 [2] = 2 ) ['qualification'] = Array ( [1] = blah [2] = blah ) ['grade'] = Array ( [1] = blah [2] = blah ) ) [vID] = 61 [Submit] = Save and Continue ) If I echo $_SESSION['post']['formid'] it writes "2", and if I echo $_SESSION['post']['edu'] it returns "Array". If I check that edu is an array (is_array($_SESSION['post']['edu])) it returns true. If I echo $_SESSION['post']['edu']['id'] it returns array, but when checked (is_array($_SESSION['post']['edu]['id'])) it returns false and I cannot echo out any of the elements. How do I successfully copy (by value, not by reference) the whole array (including its children) to an new array?

• Changed array composition, mdadm --detail still shows the old array size

  - by Prody

  I have a machine with 8 disks. I installed it with my hoster's install automation (it's OVH, I don't have physical access to it). The machine installed correctly, but it made an array that I wanted to change. It created a raid5 array across 5/8 disks and I've changed it to raid10 across 8 disks. I've done this by first --stopping the old array and then --creating the new array. It warned me that a previous array was there, but I chose to continue. So it created the array, spent 10ish hours syncing it and now that it's ready I get this strange behavior: When I fdisk p on it, I see the correct size. But when I mdadm --detail it I see the old array's size even tho I get the new composition and level. When I try to pvcreate on it, i get the old size again for some reason. Did I have to do something else? Did I miss something?

• For each result in MySQL query, push to array (complicated)

  - by Dylan Taylor

  Okay, here's what I'm trying to do. I am running a MySQL query for the most recent posts. For each of the returned rows, I need to push the ID of the row to an array, then within that ID in the array, I need to add more data from the rows. A multi-dimensional array. Here's my code thus far. $query = "SELECT * FROM posts ORDER BY id DESC LIMIT 10"; $result = mysql_query($query); while($row = mysql_fetch_array($result)){ $id = $row["id"]; $post_title = $row["title"]; $post_text = $row["text"]; $post_tags = $row["tags"]; $post_category = $row["category"]; $post_date = $row["date"]; } As you can see I haven't done anything with arrays yet. Here's an ideal structure I'm looking for, just incase you're confused. The master array I guess you could call it. We'll just call this array $posts. Within this array, I have one array for each row returned in my MySQL query. Within those arrays there is the $post_title, $post_text, etc. How do I do this? I'm so confused.. an example would be really appreciated. -Dylan

• Need to sort 3 arrays by one key array

  - by jeff6461

  I am trying to get 3 arrays sorted by one key array in objective c for the iphone, here is a example to help out... Array 1 Array 2 Array 3 Array 4 1 15 21 7 3 12 8 9 6 7 8 0 2 3 4 8 When sorted i want this to look like Array 1 Array 2 Array 3 Array 4 1 15 21 7 2 3 4 8 3 12 8 9 6 7 8 0 So array 2,3,4 are moving with Array 1 when sorted. Currently i am using a bubble sort to do this but it lags so bad that it crashes by app. The code i am using to do this is int flag = 0; int i = 0; int temp = 0; do { flag=1; for(i = 0; i < distancenumber; i++) { if(distance[i] > distance[i+1]) { temp = distance[i]; distance[i]=distance[i + 1]; distance[i + 1]=temp; temp = FlowerarrayNumber[i]; FlowerarrayNumber[i] = FlowerarrayNumber[i+1]; FlowerarrayNumber[i + 1] = temp; temp = BeearrayNumber[i]; BeearrayNumber[i] = BeearrayNumber[i + 1]; BeearrayNumber[i + 1] = temp; flag=0; } } }while (flag==0); where distance number is the amount of elements in all of the arrays, distance is array 1 or my key array. and the other 2 are getting sorted. If anyone can help me get a merge sort(or something faster, it is running on a iPhone so it needs to be quick and light) to do this that would be great i cannot figure out how the recursion works in this method and so having a hard time to get the code to work. Any help would be greatly appreciated

• from one-dimensional to two-dimensional array

Little bit harder... i also need to split on the single '_' underscore, i did this to prevent the columns getting mixed up... But the example below doesn't do the job right... $new_array = array(); foreach($MeshtagsArray as $key => $value) { $parts = explode('__', $key, 2); $parts2 = explode('_', $key, 2); $new_array[] = array( 'discriptor' => $parts[0], 'qualifier' => $parts2[1], 'major' => $parts[1], '#occurence' => $value ); So the output should be something like: [0] => Array ( [discriptor] => Female [qualifier] => [major] => N [#occurence] => 11 ........ [5] => Array ( [discriptor] => Reaction Time [qualifier] => physiology [major] => N [#occurence] => 6 Best regards, Thijs

• javascript multidimensional array?

  - by megapool020

  Hi there, I hope I can make myself clear in English and in what I want to create. I first start with what I want. I want to make a IBANcalculator that can generate 1-n IBANnumbers and also validate a given IBANnumber. IBANnumbers are used in many countries for payment and the tool I want to make can be used to generate the numbers for testing purpose. On wikipedia (Dutch site) I found a list with countries and their way of defining the IBANnumber. What I want to do it to make a kind of an array that holds all the countries with their name, the code, there IBANlength, the bankingformat and the account format. The array needs to be used to: Generate a select list (for selecting a country) used to check part for generating numbers used to check part for validating number I don't know if an array is the best way, but that's so far the most knowledge I have. I allready made a table like this that holds the info (this table isn't used anyware, but it was a good way for me to show you what I have in mind about how the structure is): <table> <tr> <td>countryname</td> <td>country code</td> <td>valid IBAN length</td> <td>Bank/Branch Code (check1, bank, branch)</td> <td>Account Number (check2, number, check3)</td> <tr> <tr> <td>Andorra</td> <td>AD</td> <td>24</td> <td>0 4n 4n</td> <td>0 12 0 </td> <tr> <tr> <td>België</td> <td>BE</td> <td>16</td> <td>0 3n 0 </td> <td>0 7n 2n</td> <tr> <tr> <td>Bosnië-Herzegovina</td> <td>BA</td> <td>20</td> <td>0 3n 3n</td> <td>0 8n 2n</td> <tr> </table> and many more ;-) I hope someone can help me with this.

• Accessing a vector<vector<int>> as a flat array

  For this array: vector<vector<int> > v; v.push_back(vector<int>(0)); v.back().push_back(1); v.back().push_back(2); v.back().push_back(3); v.back().push_back(4); I can output {1, 2, 3, 4} easily enough: cout << v[0][0] << endl; cout << v[0][1] << endl; cout << v[0][2] << endl; cout << v[0][3] << endl; To access it as a flat array I can do this: int* z = (int*)&v[0].front(); cout << z[0] << endl; cout << z[1] << endl; cout << z[2] << endl; cout << z[3] << endl; Now, how do I access the multidimensional vector as a flat multidimensional array? I cannot use the same format as accessing a single-dimensional vector: // This does not work (outputs garbage) int** n = (int**)&v.front(); cout << n[0][0] << endl; cout << n[0][1] << endl; cout << n[0][2] << endl; cout << n[0][3] << endl; The workaround I've found is to do this: int** n = new int* [v.size()]; for (size_t i = 0; i < v.size(); i++) { n[i] = &v.at(i).front(); } cout << n[0][0] << endl; cout << n[0][1] << endl; cout << n[0][2] << endl; cout << n[0][3] << endl; Is there a way to access the entire multidimensional vector like a flat c-style array without having to dynamically allocate each dimension above the data before accessing it? Speed is not critical in the implementation and clarity for maintenance is paramount. A multidimensional vector is just fine for storing the data. However, I want to also expose the data as a flat c-style array in the SDK so that it can be easily accessible by other languages. This means that exposing the vectors as an STL object is a no go. The solution I came up with works fine for my needs as I only evaluate the array once at the very end of processing to "flatten" it. However, is there a better way to go about this? Or am I already doing it the best way I possibly can without re-implementing my own data structure (overkill since my flatten code is only a few lines). Thank you for your advice, friends!
