How to Parse Domain from a URL in PHP

In PHP, the parse_url() function can be used to extract the domain from a URL. This function returns an associative array containing various components of the URL, including the host key which corresponds to the domain.

Example:

To parse the domain from the following URL:

http://google.com/dhasjkdas/sadsdds/sdda/sdads.html

Use the following code:

$url = 'http://google.com/dhasjkdas/sadsdds/sdda/sdads.html';
$parse = parse_url($url);
echo $parse['host']; // prints 'google.com'

Note:

• parse_url() does not handle mangled URLs very well, but it works well for valid URLs.
• parse_url() returns additional information about the URL, such as the scheme, path, query, and fragment.
