cURL Library Functions

This extension provides access to the cURL (Client URL Library) library for ease of access of URL-locatable network resources. For complete discussions of the capabilities of cURL, please visit http://curl.haxx.se. As of libcurl version 7.4, cURL could handle at least DICT, file, FTP, Gopher, HTTP, HTTPS, LDAP, and Telnet protocols; many advanced features of these protocols are also available. cURL support needs to be built into PHP using the --with-curl=[DIR] configure option; you also need the library itself from http://curl.haxx.se. Some of the functionality described here requires versions of libcurl at least as recent as 7.4.1 (these are noted); however, most of it needs only at least 7.2. PHP cURL support will not work with versions of libcurl older than 7.2. Similarly, all PHP cURL support requires at least PHP 4.0.2; where noted, however, PHP 4.0.4 or later is needed.
