PHP Check whether URL exists with CURL

This script helps us to check whether a URL exist or not by checking the header details.Here we are also displaying the output of the URL header details for further reference.

Complete Code

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
echo $data;

Sample output

HTTP/1.1 200 OK Date: Fri, 04 Jan 2013 14:25:55 GMT Server: Apache X-Powered-By: PHP/5.3.1 Content-Type: text/html

You may need to write some logic to extract the response code to make sure that the website exists. In the above sample output we see 200, that means a OK success status response.

If you are getting this error below

PHP Fatal error:  Uncaught Error: Call to undefined function curl_init() in check_curl.php:2

You may need to install php-curl, in my case I am using Ubuntu.

sudo apt-get install php-curl

After installing, restart php-fpm (if you are using that) or restart Apache / Nginx (may be) to refresh the configuration. Then try hitting the URL again.
