XII. Funzioni CURL, Client URL Library

Introduzione

PHP supporta libcurl, una libreria creata da Daniel Stenberg, che permette di collegarsi e comunicare con parecchi tipi di server e con parecchi tipi di protocolli. Libcurl al momento supporta i protocolli http, https, ftp, gopher, telnet, dict, file, e ldap. libcurl supporta anche i certificati HTTPS, HTTP POST, HTTP PUT, l'upload via FTP (questo pu� essere ottenuto anche con l'estensione ftp di PHP), upload attraverso una form HTTP, proxy, cookie e autenticazione con utente e password.

Queste funzioni sono state aggiunte in PHP 4.0.2.

Requisiti

Per utilizzare le funzioni CURL occorre installare il pacchetto CURL. PHP richiede che si usi CURL 7.0.2-beta o successivi. PHP non funzioner� con alcuna versione di CURL antecedente alla 7.0.2-beta. Dalla versione 4.2.3 di PHP � necessario usare CURL versione 7.9.0 o successiva. Con PHP 4.3.0 occorre avere CURL 7.9.8 o successive. PHP 5.0.0 molto probabilmente richieder� CURL 7.10.5 o successiva.

Installazione

Al fine di utilizzare il supporto CURL occorre anche compilare PHP con --with-curl[=DIR] dove DIR � il percorso della directory che contiene le directory lib e include. Nella directory "include" ci dovrebbe essere una cartella chiamata "curl" che dovrebbe contenere i file easy.h e curl.h. Ci dovrebbe essere un file chiamato libcurl.a nella directory "lib". A cominciare da PHP 4.3.0 si pu� configurare PHP all'uso di CURL per gli url stream --with-curlwrappers.

Nota agli utenti Win32: Per abilitare questo modulo in ambiente Windows, occorre copiare libeay32.dll e ssleay32.dll dalla cartella delle DLL del pacchetto PHP/Win32 nella cartella SYSTEM32 della propria macchina Windows. (Es: C:\WINNT\SYSTEM32 o C:\WINDOWS\SYSTEM)

Costanti predefinite

Queste costanti sono definite da questa estensione e sono disponibili solo se l'estensione � stata compilata nel PHP o se � stata caricata dinamicamente a runtime.

Esempi

Una volta compilato PHP con supporto CURL, si possono usare le funzioni CURL. L'idea di fondo che sta dietro le funzioni CURL �: si inizializza una sessione CURL usando curl_init(), si impostano le opzioni per il trasferimento tramite curl_setopt(), si esegue la sessione usando curl_exec() e quindi si termina la sessione con curl_close(). Qui di seguito si trova un esempio che fa uso delle funzioni CURL per scaricare la homepage del sito example.com e metterla in un file:
Esempio 1. Usare il modulo CURL di PHP per scaricare la homepage di example.com

<?php $ch = curl_init("http://www.example.com/"); $fp = fopen("example_homepage.txt", "w"); curl_setopt($ch, CURLOPT_FILE, $fp); curl_setopt($ch, CURLOPT_HEADER, 0); curl_exec($ch); curl_close($ch); fclose($fp); ?>

Sommario
curl_close -- Chiude una sessione CURL
curl_errno -- Restituisce il numero dell'ultimo errore
curl_error -- Restituisce una stringa contenente l'ultimo errore relativo alla sessione corrente
curl_exec -- Esegue una sessione CURL
curl_getinfo -- Ottiene informazioni relative a un determinato trasferimento
curl_init -- Inizializza una sessione CURL
curl_multi_add_handle -- Aggiunge un handle cURL ad un multi handle cURL
curl_multi_close -- Chiude un set di handle cURL
curl_multi_exec -- Esegue la sotto-connessione dell'handle cURL corrente
curl_multi_getcontent -- Restituisce il contenuto di un handle cURL se � impostato CURLOPT_RETURNTRANSFER
curl_multi_info_read -- Ottiene informazioni sui trasferimenti correnti
curl_multi_init -- Restituisce un nuovo multi handle cURL
curl_multi_remove_handle -- Rimuove un multi handle da un set di handle cURL
curl_multi_select -- Restituisce tutti i socket associati alla estensione cURL che possono essere "selected"
curl_setopt -- Imposta una opzione per un trasferimento CURL
curl_version -- Restituisce la versione di CURL in uso

Hi, I spent half a day to get it out, it isn't well documented.



If you want to use the same cURL session to make a POST request and then a GET request you need to use the CURLOPT_HTTPGET option, otherwise cURL will continue to execute a POST request. Sample code follows.



<?php 

    // curl initialization

    curl_setopt($ch, CURLOPT_POST, 1);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);

    // execute a POST request

    curl_setopt($ch, CURLOPT_POST, 0);

    curl_setopt($ch, CURLOPT_POSTFIELDS, null);

    curl_setopt($ch, CURLOPT_HTTPGET, 1); 

    // execute a GET request on the same cURL session

?>

If I want to use CURLOPT_COOKIEFILE and CURLOPT_POSTFIELDS in the same request.

The post fields are not inserted in the HTTP header as I expected!



   $url = "http://www.url.com";

   $data = "key1=val1&key2=val2";



   $ch = curl_init(); 

   curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 

   curl_setopt($ch, CURLOPT_URL, $url); 

   curl_setopt($ch, CURLOPT_COOKIEFILE,     "cook");

   curl_setopt($ch, CURLOPT_POST,           1); 

   curl_setopt($ch, CURLOPT_POSTFIELDS,     $data); 



   $result = curl_exec($ch); // run the whole process 

   curl_close($ch);  

   echo $result;

It took me quite some to to figure out how to get Curl (with SSL), OpenSSL and PHP to play nicely together.



After reinstalling MS-VC7 and compiling OpenSSL to finally realise this was'nt nesscary.



If your like me and like *Nix systems more than Windows then you'll most probly have similar problems.



I came across this, on a simple google with the right keywords.



http://www.tonyspencer.com/journal/00000037.htm



I read thru that and found my mistake.



Its just a small list of notes, I found them to be the best I've found on the subject and the most simplist.



Dont forget to add a simple line like this into your scripts to get them working on Win32.



<?php

if($WINDIR) curl_setopt($curl, CURLOPT_CAINFO, "c:\\windows\\ca-bundle.crt");

?>



Last note: ca-bundle.crt file is located in the Curl download. I stored mine in the windows directory and apache/php can access it fine.



All the best and I hope this helps.

You can request (and have deflated for you) compressed http (from mod_gzip or ob_gzhandler, for instance) by using the following:



curl_setopt($ch,CURLOPT_ENCODING , "gzip");



This seems to work fine with the latest php (4.3.4) curl (7.11.0) and zlib (1.1.4) under linux.  This is much more elegant than forcing the Accept-Encode header and using gzdeflate on an edited result.

I know that many people suffer from cURL when trying to send XML data. I solved this problem and want to share it with you:





I was trying to send SMS messages with a SMS service provider. They gave me the following ASP code, where you send data as XML and receive a response in XML as well:





url = "http://...someaddress/somefile.asp";


xmldata ="<XMLtag1>many other tags, data here</XMLtag1>";


Set ob = Server.CreateObject("Msxml2.XMLHTTP")


ob.Open "POST",url,false


ob.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"


ob.Send xmldata


...then recieve code was here...





This is done in PHP using cURL library in this way:





<?php


$XPost = "<XMLcontent>sameas above</XMLcontent>"


$url = "..same URL as above.."; 


$ch = curl_init();    // initialize curl handle 


curl_setopt($ch, CURLOPT_URL,$url); // set url to post to 


curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable 


curl_setopt($ch, CURLOPT_TIMEOUT, 4); // times out after 4s 


curl_setopt($ch, CURLOPT_POSTFIELDS, $XPost); // add POST fields 


$result = curl_exec($ch); // run the whole process 


echo $result; //contains response from server


?>





Some say that you should use CURLOPT_CUSTOMREQUEST, CURLOPT_HTTPHEADER and etc. to perform this task , as you can see you don't need those at all.





Hope it will help those who tries to simulate Msxml2.XMLHTTP or simply try sending XML data over PHP.

Here's how I was able to post arrays using Curl:



$array_of_vars[]="var1";

$array_of_vars[]="var2";

$array_of_vars[]="var3";

$array_of_vars[]="var4";



$submit_url = "http://www.example.com/reads_post.php";

$formvars["feild1"] = "feild1";



for ($i=0;$i<sizeof($array_of_vars);$i++)

    $formvars["array_of_vars[$i]"] = $dna[$i];



    

// init curl handle

$ch = curl_init($submit_url);

curl_setopt($ch, CURLOPT_VERBOSE, 1);

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $formvars);



// perform post

$rr=curl_exec($ch);

echo $rr;

curl_close($ch);

The following scripts show how to post form to a web server via https.  I modified rodrigo posting because it did not work for me on IIS5.

<?php

    $url = 'https://www.yourserver.com/yourrequest;

    $params = "name=your_name&email=youremail@mail.com";

    $user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";



    $ch = curl_init();

    curl_setopt($ch, CURLOPT_POST,1);

    curl_setopt($ch, CURLOPT_POSTFIELDS,$params);

    curl_setopt($ch, CURLOPT_URL,$url);

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);

    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);  // this line makes it work under https



    $result=curl_exec ($ch);

    curl_close ($ch);



    echo("Results: <br>".$result);

I managed to use curl to retrieve information from severs on ports other than 80 or 443 (for https) on some installations but not on all. 

If you get an "CURLE_COULDNT_CONNECT /* 7 */" error, try adding the port : (for example)

curl_setopt($ch, CURLOPT_PORT, $_SERVER['SERVER_PORT']);

IMHO the example code is somewhat confusing; the fopen() and fclose() are not needed at all, AFAICT.



By default the resulting data/page of the external server is just printed out. To assign the result of the curl session to a variable, one can use

- output buffering (see ob_start(), ob_get_contents())

- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

With the latter, the result of curl_exec is the actual data instead of a boolean.

Here's a little code snippet if you need the last-modified-time for a remote file as filemtime() does not work on those. :)



$modified = "";

function read_header($ch, $header)

{

    global $modified;

    $length = strlen($header);

    if(strstr($header, "Last-Modified:"))

    {

        $modified = substr($header, 15);

    }

    return $length;

}



function last_mod($remote_file)

{

    global $modified;

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $remote_file);

    curl_setopt($ch, CURLOPT_HEADER, 1);

    curl_setopt($ch, CURLOPT_NOBODY, 1);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header');



    $headers = curl_exec ($ch);

    curl_close ($ch);

    return $modified;

}



use something like

    echo strtotime(last_mod("http://www.php.net/"));

to get the time as an Unix timestamp or

    echo last_mod("http://www.php.net/");

to get the gmdate()-like time.

If you want to Curl to follow redirects and you would also like Curl to echo back any cookies that are set in the process, use this:



curl_setopt($ch, CURLOPT_COOKIEJAR, '-');



'-' means stdout

if you need to install curl on a windows system, this has the best explanation:

For Win2000: To get the 4.3.1 curl dll to work with https you now need to download the latest win32 curl library from http://curl.haxx.se and snag the ca-bundle.crt file from the lib directory.  Place this somewhere handy on your webserver.



Then in your PHP script, add the following setopt line to the rest of your curl_setopt commands:



curl_setopt($ch, CURLOPT_CAFILE, 'C:\pathto\ca-bundle.crt')



This worked for me and allowed me to discontinue using the CURLOPT_SSL_VERIFYPEER set to zero hack.

When using cURL to do posts, make sure you actually specify the CURLOPT_POSTFIELDS option. Not doing so seems to make PHP core (and apache as well if you're running it through there).

If anybody has problems with getting new curl working with older version of php then ...



I got stuck with installing curl-7.10.2+php 4.0.6 or better said configuring PHP with mentioned version of curl.



After some hopeless attempts to configure curl support into PHP I saw an error message:



"checking for cURL greater than or equal to 7.8... ./configure: line 11725: test: 070a02: integer expression expected"



after which configure said: "configure: error: cURL version 7.8 or later is required to compile php with cURL support"



On the mentioned line "test" is used to compare verion from curl-sonfig with preset value 70800 but ... test expects both values to be integer. From verson 7.8 curl outputs its version in hex...



I did'nt had the time to think about fixing this - I just deleted lines responsible and got curl working :)

I wanted to import an https Web pages thanks to fopen("https://xxx", "r") or fsockopen but as far as I read, it was only possible with cURL extension (to get these functions worked with https, we have to wait the PHP 4.3 release, TBC) , so I installed it and it worked. It is quite easy, but I spend to much time on it:

First of all, here is the most important: WE DON'T NEED to compile anything to get curl worked. All the extensions that we need are already in the PHP 4.2.3 zip. So here are the instructions and links to get Apache + PHP + CURL work properly:



Downloads:

=> Apache Web server with Openssl included:

   http://www.modssl.org/contrib/ftp/contrib/ Apache_1.3.26-Mod_SSL_2.8.9-OpenSSL_0.9.6d-WIN32.zip



=> PHP 4.2.3 for Windows:

   http://www.php.net/get_download.php?df=php-4.2.3-Win32.zip



=> Optional: Openssl zip to get libeay32.dll and ssleay32.dll (I didn't need them because I used those stored in PHP zip)

http://www.modssl.org/contrib/ftp/contrib/ OpenSSL-0.9.6d-win32_RAR3_Archive_.rar



Installs:

=> Unzip Apache in Program Files folder(there should be no problem with the blank in the path):



=> Follow those instructions: http://tud.at/programm/apache-ssl-win32-howto.php3 . I didn't exactly do what they wrote but it helped a lot. I created the test certificat thanks to this link in order to test my Apache server with SSL.



=> Configure httpd (easy to find on the Web) and test Apache before going on, it avoids problems.

   I just changed the Port from 80 (http) to 443 (https) in httpd, I only wanted to perform https.

   I didn't try to get the both working together. 



=> Unzip PHP in C:\Php path (don't install it in Program Files folder, you would have troubles because of the blank this time...) 



=> Configure PHP : http://www.php.net/manual/en/install.windows.php #install.windows.manual

   WARNING: php.ini MUST be stored into the c:\winnt folder and the dlls must be stored into the c:\winnt\system32 folder.



=> Test it with Apache and phpinfo() function.



cURL:

To add cURL extension, YOU DON'T NEED to compile anything.

All the extensions that you need are in the C:\php\extensions folder. To add cURL or any other extensions:



=> Have the libeay32.dll and ssleay32.dll in the system32 folder (already done if you installed PHP)



=> Copy all dlls from php/dll/ folder to winnt/system32/ (libeay32.dll and ssleay32.dll are already there if you followed

   the previous steps)



=> Remove the ";" in front of extension=php_curl.dll in php.ini.



Those instructions come from: http://www.php.net/manual/en/install.windows.php #install.windows.extensions



And it should work, just test it with curl functions into your php script.

Using the customrequest for a complete post is wrong. Libcurl will add a partial url, the http version and the standard headers after the post data - while this works with a non-persistent connection and an apache web server, it may fail under different conditions

If you want to write your entire HTTP request without use any other CURL functions like CURLOPT_POST specify it within a curl_setopt ($ch,CURLOPT_CUSTOMREQUEST , $req) line; 


Where $req looks like (let me imagine a POST request...):





POST /destination/script HTTP/1.1


Content-length: xxx


Content-type: text/xml


host: yourhost


accept: */*


accept-encoding: gzip, deflate


accept-language: en-us


connection: close; Keep-Alive


...


your POST data


...








CURLOPT_CUSTOMREQUEST is not documented?!? but it's useful and amazing!

I used to download www pages to my script and one of the pages was different in MS explorer and different, when I downloaded it. Namely, information, I was really interested in was missing. That was because the server on the other bank of the river was looking at who is downloading the page. Everything got fixed when I pretended I was MSIE. It is done with curl. Here is a function, that you may use in similar situation





function download_pretending($url,$user_agent) {


   $ch = curl_init();


   curl_setopt ($ch, CURLOPT_URL, $url);


   curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);


   curl_setopt ($ch, CURLOPT_HEADER, 0);


   curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);


   $result = curl_exec ($ch); 


   curl_close ($ch);


   return $result;


}
