(PHP 4 >= 4.0.2, PHP 5, PHP 7)
curl_exec — Perform a cURL session
Description
curl_exec
( CurlHandle $handle
) : string|bool
Execute the given cURL session.
This function should be called after initializing a cURL session and all the options for the session are set.
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.
