What is the difference between a link and a button in terms of functionality in PHP?

In PHP, a link is typically used to navigate to a different page or resource, while a button is used to trigger a specific action or function within the current page. Links are created using the anchor tag <a>, while buttons are created using the button tag <button>. To implement a link, you would specify the destination URL in the href attribute of the anchor tag, while for a button, you would add an onclick event handler to trigger the desired action.

&lt;!-- Example of a link --&gt;
&lt;a href=&quot;destination.php&quot;&gt;Click here to go to another page&lt;/a&gt;

&lt;!-- Example of a button --&gt;
&lt;button onclick=&quot;myFunction()&quot;&gt;Click me&lt;/button&gt;
