How can you use PHP to read a directory and generate clickable links for PDF files?

To generate clickable links for PDF files in a directory using PHP, you can use the `scandir()` function to read the directory and then loop through the files to generate links for PDF files. You can check the file extension using `pathinfo()` and generate links only for PDF files. 

<?php
$dir = 'path/to/directory';

$files = scandir($dir);

foreach($files as $file){
    $fileInfo = pathinfo($file);
    if(isset($fileInfo['extension']) && $fileInfo['extension'] == 'pdf'){
        echo '<a href="' . $dir . '/' . $file . '">' . $file . '</a><br>';
    }
}
?>
