XII. CURL, Client URL Library Functions

Introduction

   PHP supports libcurl, a library created by Daniel Stenberg, that
   allows you to connect and communicate to many different types of
   servers with many different types of protocols. libcurl currently
   supports the http, https, ftp, gopher, telnet, dict, file, and ldap
   protocols. libcurl also supports HTTPS certificates, HTTP POST, HTTP
   PUT, FTP uploading (this can also be done with PHP's ftp extension),
   HTTP form based upload, proxies, cookies, and user+password
   authentication.

   These functions have been added in PHP 4.0.2.

Requirements

   In order to use the CURL functions you need to install the CURL
   package. PHP requires that you use CURL 7.0.2-beta or higher. PHP will
   not work with any version of CURL below version 7.0.2-beta. In PHP
   version 4.2.3, you will need CURL version 7.9.0 or higher. From PHP
   4.3.0, you will need a CURL version that's 7.9.8 or higher. PHP 5.0.0
   will most likely require a CURL version greater than 7.10.5

Installation

   To use PHP's CURL support you must also compile PHP --with-curl[=DIR]
   where DIR is the location of the directory containing the lib and
   include directories. In the "include" directory there should be a
   folder named "curl" which should contain the easy.h and curl.h files.
   There should be a file named libcurl.a located in the "lib" directory.
   Beginning with PHP 4.3.0 you can configure PHP to use CURL for url
   streams --with-curlwrappers.

     Note to Win32 Users: In order to enable this module on a Windows
     environment, you must copy libeay32.dll and ssleay32.dll from the
     DLL folder of the PHP/Win32 binary package to the SYSTEM folder of
     your Windows machine. (Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM)

Examples

   Once you've compiled PHP with CURL support, you can begin using the
   CURL functions. The basic idea behind the CURL functions is that you
   initialize a CURL session using the curl_init(), then you can set all
   your options for the transfer via the curl_setopt(), then you can
   execute the session with the curl_exec() and then you finish off your
   session using the curl_close(). Here is an example that uses the CURL
   functions to fetch the example.com homepage into a file:

   Example 1. Using PHP's CURL module to fetch the example.com homepage
   <?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);
   ?>

   Table of Contents
   curl_close -- Close a CURL session
   curl_errno -- Return the last error number
   curl_error --  Return a string containing the last error for the
          current session

   curl_exec -- Perform a CURL session
   curl_getinfo --  Get information regarding a specific transfer
   curl_init -- Initialize a CURL session
   curl_multi_add_handle --  Add a normal cURL handle to a cURL multi
          handle

   curl_multi_close --  Close a set of cURL handles
   curl_multi_exec --  Run the sub-connections of the current cURL handle

   curl_multi_getcontent --  Return the content of a cURL handle if
          CURLOPT_RETURNTRANSFER is set

   curl_multi_info_read --  Get information about the current transfers
   curl_multi_init --  Returns a new cURL multi handle
   curl_multi_remove_handle --  Remove a multi handle from a set of cURL
          handles

   curl_multi_select --  Get all the sockets associated with the cURL
          extension, which can then be "selected"

   curl_setopt -- Set an option for a CURL transfer
   curl_version -- Return the current CURL version
