In PHP, you can check if a string is a valid URL or not by using the filter_var() function with the FILTER_VALIDATE_URL filter. Here's an example code snippet:



$url = "";

if (filter_var($url, FILTER_VALIDATE_URL) !== false) {

echo "$url is a valid URL";

} else {

echo "$url is not a valid URL";


In this example, the filter_var() function checks if the $url variable is a valid URL using the FILTER_VALIDATE_URL filter. If the URL is valid, it will return the URL string, otherwise it will return false.
