How to get the Domain Name from URL in PHP

PHP is a programming language almost exclusively used to create web applications.

A good reason for this is PHP's ease-of-use regarding anything to do with the web.

One of the things PHP makes easy is working with URLs and paths.

In this post, we'll learn how to extract the domain name from a URL using PHP.

How to get the domain name from a URL in PHP

Let's start out with an example URL:

PHP
$url = "https://sabe.io/blog/php-domain-name-url";

To get the domain name from this, we must first parse the URL using PHP's built-in parse_url() function.

PHP
$url = "https://sabe.io/blog/php-domain-name-url";

$parsed = parse_url($url);

Now that we've parsed the URL, we just simply need to get the host property from the $parsed variable which will give us the domain name.

PHP
$url = "https://sabe.io/blog/php-domain-name-url";

$parsed = parse_url($url);

$host = $parsed["host"];

echo($host);

BASH
sabe.io

Keep in mind that you can also get the other properties, such as the scheme and path:

PHP
$url = "https://sabe.io/blog/php-domain-name-url";

$parsed = parse_url($url);

$host = $parsed["host"];
$scheme = $parsed["scheme"];
$path = $parsed["path"];

echo($host);
echo($scheme);
echo($path);

BASH
sabe.io
https
/blog/php-domain-name-url

Conclusion

In this post, we looked at how to extract the domain name from a URL using PHP.

Simply use the parse_url() function to parse a URL, then get the host property to get your domain name.
