I'm using CURL to get the status of a site, if it's up/down or redirecting to another site. I want to get it as streamlined as possible, but it's not working well.
<?php $ch = curl_init($url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_TIMEOUT,10); $output = curl_exec($ch); $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); return $httpcode; ?>
I have this wrapped in a function. It works fine but performance is not the best because it downloads the whole page, thing in if I remove
$output = curl_exec($ch); it returns
0 all the time.
Does anyone know how to make the performance better?
First make sure if the URL is actually valid (a string, not empty, good syntax), this is quick to check server side. For example, doing this first could save a lot of time:
Make sure you only fetch the headers, not the body content:
For more details on getting the URL status http code I refer to another post I made (it also helps with following redirects):
