Hi in the function below there is bug, because there can be more digits 200 in the header, like 2009
for example. Here is the fix:
<?php
function checkImage($image_url, $timeout = 3) {
$ch = curl_init($image_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'HEAD');
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_HEADER, true);
$res = curl_exec($ch);
curl_close($ch);
preg_match_all("/HTTP\/1\.[1|0]\s(\d{3})/", $res, $matches);
$code = (int) end($matches[1]);
if ($res !== false && $code == 200) {
return ((bool) true);
} else {
return ((bool) false);
}
}
?>
