PHP Client URL Library--curl

Introduction and Installation Configuration

PHP-supported Libcurl libraries created by Daniel Stenberg allow you to connect and communicate with a variety of servers using various types of protocols. Libcurl currently supports HTTP, HTTPS, FTP, Gopher, Telnet, dict, file, and LDAP protocols. Libcurl also supports HTTPS authentication, HTTP POST, HTTP PUT, FTP upload (This can also be done via PHP's FTP extension), HTTP forms-based uploads, proxies, cookies, and Username + password Authentication.

These functions are introduced in PHP 4.0.2.

In order to use the PHP curl function, you need to install the»libcurl package.

To use PHP's curl support you must compile PHP with the--with-curl[=dir] option, dir is the directory path that contains Lib and include. In the Include directory, you must have a folder called Curl, which contains easy.h and curl.h. There should be a file named Libcurl.a in the Lib folder. For PHP 4.3.0 You can configure--with-curlwrappers to use the URL stream for curl.

Note:win32 User Note
To use this module in a Windows environment, Libeay32.dll and Ssleay32.dll must be placed in the directory contained in the PATH environment variable. Don't use the Libcurl.dll on the Curl website.
