Check If File Exists using PHP

Here’s a useful PHP function for when you need to check if a file or folder of a certain name already exists on your server.

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);
return $headers['http_code'];
$check_url_status = check_url($url);
if ($check_url_status == '200') {
echo "Link Works"; }
else {
echo "Broken Link"; }
