The cURL Adapter

cURL is a standard HTTP client library that is distributed with many operating systems and can be used in PHP via the cURL extension. It offers functionality for many special cases which can occur for a HTTP client and make it a perfect choice for a HTTP adapter. It supports secure connections, proxy, all sorts of authentication mechanisms and shines in applications that move large files around between servers.

Example 492. Setting cURL options

= array(
'adapter'   => 'Zend_Http_Client_Adapter_Curl',
'curloptions' => array(CURLOPT_FOLLOWLOCATION => true),
$client = new Zend_Http_Client($uri$config);

By default the cURL adapter is configured to behave exactly like the Socket Adapter and it also accepts the same configuration parameters as the Socket and Proxy adapters. You can also change the cURL options by either specifying the 'curloptions' key in the constructor of the adapter or by calling setCurlOption($name, $value). The $name key corresponds to the CURL_* constants of the cURL extension. You can get access to the Curl handle by calling $adapter->getHandle();

Example 493. Transfering Files by Handle

You can use cURL to transfer very large files over HTTP by filehandle.

$putFileHandle fopen("filepath""r");

$adapter = new Zend_Http_Client_Adapter_Curl();
$client = new Zend_Http_Client();
'curloptions' => array(
CURLOPT_INFILE => $putFileHandle,
