Are there any specific PHP libraries or resources that can help in building a search function for files on a web server?

To build a search function for files on a web server using PHP, you can utilize the `glob()` function to retrieve a list of files matching a specified pattern. You can then iterate through the list of files and perform a search based on the file names or contents.

<?php
$searchTerm = 'example'; // Search term
$searchResults = [];
$files = glob('path/to/files/*'); // Get list of files

foreach ($files as $file) {
    if (strpos($file, $searchTerm) !== false) {
        $searchResults[] = $file;
    } else {
        $content = file_get_contents($file);
        if (strpos($content, $searchTerm) !== false) {
            $searchResults[] = $file;
        }
    }
}

print_r($searchResults);
?>
