Php client URL library -- cURL

PHP extension client URL library -- cURL

Introduction and installation configuration

The libcurl library created by Daniel Stenberg supported by PHP allows you to connect to and communicate with various servers using various protocols. Libcurl currently supports http, https, ftp, gopher, telnet, dict, file, and ldap protocols. Libcurl also supports HTTPS authentication, http post, http put, and FTP upload (this can also be completed through the FTP extension of PHP) HTTP form-based Upload, proxy, cookies, user name + password authentication.

These functions are introduced in PHP 4.0.2.

To use the PHP cURL function, you need to install the» libcurl package.

To support PHP cURL, you must add the -- with-curl [= DIR] option when compiling PHP. DIR is the directory path containing lib and include. The include directory must contain a folder named curl that contains easy. h and curl. h. The lib folder should contain a file named libcurl.. For PHP 4.3.0, you can configure -- with-curlwrappers to enable cURL to use URL streams.

Note: Win32 user attention
To use this module in Windows, libeay32.dll and ssleay32.dll must be placed in the directory included in the PATH environment variable. Do not use libcurl. dll on the cURL website.
