How can a PHP beginner remove a slash before a directory in a generated link?

When generating a link in PHP, if a slash appears before a directory name, it can cause issues with the URL structure. To remove the slash before a directory in a generated link, you can use the trim() function to remove any leading slashes from the directory name before appending it to the link. 

<?php
$directory = "/example_directory";
$link = "http://www.example.com" . trim($directory, '/');
echo $link;
?>
