What is the recommended approach for opening a small window when clicking on a link using PHP?

When clicking on a link, you can use PHP to open a small window by utilizing JavaScript's `window.open()` function. This function allows you to specify the URL of the page to be opened in a new window, as well as the dimensions and other properties of the new window. By combining PHP and JavaScript, you can create a link that opens a small window when clicked.

<a href="#" onclick="window.open('yourpage.php', 'smallwin', 'width=400,height=400'); return false;">Click me to open a small window</a>
