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:

Example:

<?php
  
  $url = "https://www.example.com";
  
  if (filter_var($url, FILTER_VALIDATE_URL) !== false) {
      echo "$url is a valid URL";
  } else {
      echo "$url is not a valid URL";
