curl_exec

(PHP 4 >= 4.0.2, PHP 5, PHP 7)

curl_exec — Perform a cURL session

Description

curl_exec ( resource $ch ) : mixed

Execute the given cURL session.

This function should be called after initializing a cURL session and all the options for the session are set.

Parameters

ch

A cURL handle returned by curl_init().

Return Values

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

Warning

This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.

Note:

Note that response status codes which indicate errors (such as 404 Not found) are not regarded as failure. curl_getinfo() can be used to check for these.
