What are the steps to create an external CSS file in PHP and link it to a PHP file?

To create an external CSS file in PHP and link it to a PHP file, you need to first create a separate CSS file with the styling you want. Then, in your PHP file, you can use the <link> tag to link to the external CSS file by specifying the file path in the href attribute.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;

    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;styles.css&quot;&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Welcome to my website&lt;/h1&gt;
    &lt;p&gt;This is a paragraph with some text.&lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;
