Description
stringbool curl_exec(CurlHandle $handle)
This function should be called after initializing a cURL session and all
the options for the session are set.
Parameters

A cURL handle returned by
curl_init.
Return Values
On success, this function flushes the result directly to the
stdout and returns true, or false on failure.
However, if the CURLOPT_RETURNTRANSFER
option is set, it will return
the result on success, false on failure.
WarningThis 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.
