You can check for broken link using this function:
function check_url($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch , CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
$headers = curl_getinfo($ch);
curl_close($ch);
return $headers['http_code'];
}
You need to have CURL installed for this to work. Now you can check for broken links using:
$check_url_status = check_url($url);
if ($check_url_status == '200')
echo "Link Works";
else
echo "Broken Link";
