  • php curl: how can i emulate a get request exactly like a web browser?

    - by ufk
    Hi. there are websites that when i open specific ajax request on browser i get the resulted page, but when i try to load them with curl, i receive an error from the server. how can i properly emulate a get request to the server that will simulate a browser ? that's what i'm doing: $url="https://new.aol.com/productsweb/subflows/ScreenNameFlow/AjaxSNAction.do?s=username&f=firstname&l=lastname"; ini_set('user_agent', 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); $result=curl_exec($ch); print $result;

  • How can this PHP/FQL code be modified to increase the performance and usability?

    - by Kaoukkos
    I try to get some insights from the pages I am administrator on Facebook. What my code does, it gets the IDs of the pages I want to work with through mySQL. I did not include that part though.After this, I get the page_id, name and fan_count of each of those facebook IDs and are saved in fancounts[]. Using the IDs ( pages[] ) I get two messages max from each page. There may be no messages, there may be 1 or 2 messages max. Possibly I will increase it later. messages[] holds the messages of each page. I have two problems with it. It has a very slow performance I can't find a way to echo the data like this: ID - Name of the page - Fan Count Here goes the first message Here goes the second one //here is a break ID - Name of the page 2 - Fan Count Here goes the first message of page 2 Here goes the second one of page 2 My questions are, how can the code be modified to increase performance and show the data as above? I read about fql.multiquery. Can it be used here? Please provide me with code examples. Thank you $pages = array(); // I get the IDs I want to work with $pagesIds = implode(',', $pages); // fancounts[] holds the page_id, name and fan_count of the Ids I work with $fancounts = array(); $pagesFanCounts = $facebook->api("/fql", array( "q" => "SELECT page_id, name, fan_count FROM page WHERE page_id IN ({$pagesIds})" )); foreach ($pagesFanCounts['data'] as $page){ $fancounts[] = $page['page_id']."-".$page['name']."-".$page['fan_count']; } //messages[] holds from 0 to 2 messages from each of the above pages $messages = array(); foreach( $pages as $id) { $getMessages = $facebook->api("/fql", array( "q" => "SELECT message FROM stream WHERE source_id = '$id' LIMIT 2" )); $messages[] = $getMessages['data']; } // this is how I print them now but it does not give me the best output. ( thanks goes to Mark for providing me this code ) $count = min(count($fancounts),count($messages)); for($i=0; $i<$count; ++$i) { echo $fancounts[$i],'<br>'; foreach($messages[$i] as $msg) { echo $msg['message'],'<br>'; } }

  • What is the safest way for a PHP script to connect to a local PostgreSQL instance on Linux?

    - by Botond Balázs
    I think if I granted the apache user appropriate privileges and used the ident authentication method, that would make the connection more secure because then the password wouldn't need to be stored in a connection string. Also, that way the security of the connection would depend on how secure the host system is. I disabled root login over ssh and only permit public key authentication so I think it is pretty secure. Does this have any significant security benefits or is it just wishful thinking? Is it necessary at all?

  • Bad performance function in PHP. With large files memory blows up! How can I refactor?

    - by André
    Hi I have a function that strips out lines from files. I'm handling with large files(more than 100Mb). I have the PHP Memory with 256MB but the function that handles with the strip out of lines blows up with a 100MB CSV File. What the function must do is this: Originally I have the CSV like: Copyright (c) 2007 MaxMind LLC. All Rights Reserved. locId,country,region,city,postalCode,latitude,longitude,metroCode,areaCode 1,"O1","","","",0.0000,0.0000,, 2,"AP","","","",35.0000,105.0000,, 3,"EU","","","",47.0000,8.0000,, 4,"AD","","","",42.5000,1.5000,, 5,"AE","","","",24.0000,54.0000,, 6,"AF","","","",33.0000,65.0000,, 7,"AG","","","",17.0500,-61.8000,, 8,"AI","","","",18.2500,-63.1667,, 9,"AL","","","",41.0000,20.0000,, When I pass the CSV file to this function I got: locId,country,region,city,postalCode,latitude,longitude,metroCode,areaCode 1,"O1","","","",0.0000,0.0000,, 2,"AP","","","",35.0000,105.0000,, 3,"EU","","","",47.0000,8.0000,, 4,"AD","","","",42.5000,1.5000,, 5,"AE","","","",24.0000,54.0000,, 6,"AF","","","",33.0000,65.0000,, 7,"AG","","","",17.0500,-61.8000,, 8,"AI","","","",18.2500,-63.1667,, 9,"AL","","","",41.0000,20.0000,, It only strips out the first line, nothing more. The problem is the performance of this function with large files, it blows up the memory. The function is: public function deleteLine($line_no, $csvFileName) { // this function strips a specific line from a file // if a line is stripped, functions returns True else false // // e.g. // deleteLine(-1, xyz.csv); // strip last line // deleteLine(1, xyz.csv); // strip first line // Assigna o nome do ficheiro $filename = $csvFileName; $strip_return=FALSE; $data=file($filename); $pipe=fopen($filename,'w'); $size=count($data); if($line_no==-1) $skip=$size-1; else $skip=$line_no-1; for($line=0;$line<$size;$line++) if($line!=$skip) fputs($pipe,$data[$line]); else $strip_return=TRUE; return $strip_return; } It is possible to refactor this function to not blow up with the 256MB PHP Memory? Give me some clues. Best Regards,

  • Why does a PHP function with no parameters require parentheses?

    - by MarkRobinson
    I just spent 3 hours wondering why I couldn't start a session, then realised that I used: session_start; when I should have used: session_start(); I received no error messages at all! Perhaps then, I thought, it's a lazy way to differentiate functions from variables - but then remembered that it can't be as variables require a $ Can anyone tell me why parentheses are required then, and also why no error is given when they aren't used?

  • why libxml2 quotes starting double slash in CDATA with javascript

    - by Vincenzo
    This is my code: <?php $data = <<<EOL <?xml version="1.0"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <script type="text/javascript"> //<![CDATA[ var a = 123; // JS code //]]> </script> </html> EOL; $dom = new DOMDocument(); $dom->preserveWhiteSpace = false; $dom->formatOutput = false; $dom->loadXml($data); echo '<pre>' . htmlspecialchars($dom->saveXML()) . '</pre>'; This is result: <?xml version="1.0"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <script type="text/javascript"><![CDATA[ //]]><![CDATA[ var a = 123; // JS code //]]><![CDATA[ ]]></script></html> If and when I remove the DOCTYPE notation from XML document, CDATA works properly and leading/trailing double slash is not turned into CDATA. What is the problem here? Bug in libxml2? PHP version is 5.2.13 on Linux. Thanks.

  • I'm new to OOP/PHP. What's the practicality of visibility and extensibility in classes?

    - by marcdev
    I'm obviously brand new to these concepts. I just don't understand why you would limit access to properties or methods. It seems that you would just write the code according to intended results. Why would you create a private method instead of simply not calling that method? Is it for iterative object creation (if I'm stating that correctly), a multiple developer situation (don't mess up other people's work), or just so you don't mess up your own work accidentally?

  • How to modify a xml file using PHP? use a node to retrieve the value of new child nodes and add them

    - by Avinash Sonee
    I have pasted the example of what I need here : http://pastie.org/1005178 I have a xml file with say the following info <state> <info> <name>hello</name> <zip>51678</zip> </info> <info> <name>world</name> <zip>54678</zip> </info> </state> Now I need to create a new xml file which has the following <state> <info> <name>hello</name> <zip>51678</zip> <lat>17.89</lat> <lon>78.90</lon> </info> <info> <name>world</name> <zip>54678</zip> <lat>16.89</lat> <lon>83.45</lon> </info> </state> So, basically I need to add lat and lon nodes to each info element. these lat and lon correspond to the zip code which are stored in a mysql file which contains 3 fields - pin, lat and lon How do i do this recursively. I have say 1000 info elements in a file Please give me a sample code because I have already tried using simplexml and read the documentation but doesn't see to understand it properly

  • Using PHP, can I put variables inside of variables?

    - by Rob
    For example, take this code: $ch = curl_init($resultSet['url']."?get0=get0&get1=".$get1."&get2=".$get2."&get3=".$get3); This of course, looks very ugly, and kind of a pain in the ass to read. So my question is, would I be able to use something like this: $allgets ="?act=phptools&host=".$host."&time=".$duration."&port=".$port; $ch = curl_init($resultSet['url'] . $allgets); Very simple question I suppose, but my server is undergoing maintenance, so I can't upload it and test it myself. I suppose a yes or no answer will suffice, but if you have a more efficient way of doing this, that would be even better. :)

  • Is it better to echo javascript in raw format with php, or echo a script include that has been minif

    - by Scarface
    Hey guys quick question, I am currently echoing a lot of javascript that is based conditionally on login status and other variables. I was wondering if it would be better to simply echo the script include like <script type="text/javascript" src="javascript/openlogin.js"></script> that has been run through a minifying program and been gzipped or to echo the full script in raw format. The latter suggestion is messier to me but it reduces http requests while the latter would probably be smaller but take more cpu? Just wondering what some other people think. Thanks in advance for any advice.

  • How can I use Amazon's API in PHP to search for books?

    - by TerranRich
    I'm working on a Facebook app for book sharing, reviewing, and recommendations. I've scoured the web, searched Google using every search phrase I could think of, but I could not find any tutorials on how to access the Amazon.com API for book information. I signed up for an AWS account, but even the tutorials on their website didn't help me one bit. They're all geared toward using cloud computing for file storage and processing, but that's not what I want. I just want to access their API to search info on books. Kind of like how http://openlibrary.org/ does it, where it's a simple URL call to get information on a book (but their databases aren't nearly as populated as Amazon's). Why is it so damned hard to find the information I need on Amazon's AWS site? If anybody could help, I would greatly appreciate it.

  • Is there a simple way to "roll your own forms" for mysql in php, for example in jquery?

    - by talkingnews
    I've been googling around for a really simple way of making what is, in effect, nothing more than an enhanced phpMySql. In a mysql database, I have: Name, address, phone, website etc, plus 2 or 3 custom fields. This data is pulled out to make a website. All I want is to be able to make a freeform form, a bit like Access, but for the web, and the only thing I want to do over and above normal field editing would be to have a list of when I contact them, what was said, and perhaps a reminder when the next action is due. I've looked at so many CRMs my mind is boggling, and they all do WAY more than I need. I don't have leads or accounts, all I have is the need to make sure than when I update the person's details, and for that data to be in the same DB as my site is generate from. I'm happy to learn if I can get pointed in the right direction, and I have a feeling that something like what I want might lie in the direction of jquery. It's just that there's so much good jquery stuff about, I can't see the wood for the trees! Thanks.

  • PHP output of foreach loop into a new array.

    - by RobHardgood
    I know I'm probably missing something easy, but I have a foreach loop and I'm trying to modify the values of the first array, and output a new array with the modifications as the new values. Basically I'm starting with an array: 0 = A:B 1 = B:C 2 = C:D And I'm using explode() to strip out the :'s and second letters, so I want to be left with an array: 0 = A 1 = B 2 = C The explode() part of my function works fine, but I only seem to get single string outputs. A, B, and C.

  • Does php mvc framework agavi use CRUD compliant to REST?

    - by txwikinger
    The agavi framework uses the PUT request for create and POST for updating information. Usually in REST this is used the other way around (often referring to POST adding information while PUT replacing the whole data record). If I understand it correctly, the important issue is that PUT must be idempotent, while POST does not have this requirement. Therefore, I wounder how creating a new record can be idempotent (i.e. multiple request do not lead to multiple creations of a record) in particular when usually the ORM uses an id as a primary key and the id of a new record would not be known to the client (since it is autocreated in the database), hence cannot be part of the request. How does agavi maintain the requirement of idempotence in light of this for the PUT request. Thanks.

  • MySQL query being performed when PHP if condition not met?

    - by Ryan
    The script I'm using is if($profile['username'] == $user['username']) { $db->query("UPDATE users SET newcomments = 0 WHERE username = '$user[username]'"); echo "This is a test"; } (Note that $db-query is exactly the same as mysql_query) For some very odd reason, the MySQL query is being performed even if the defined condition is false The "This is a test" works properly and only appears when the condition is met, but the MySQL query is performed anyway Whats the problem with it?
