Are there any specific PHP functions or libraries that can streamline the process of searching for files in a directory?

When searching for files in a directory using PHP, the `glob()` function can be very useful as it allows you to easily retrieve an array of file paths matching a specified pattern. By combining `glob()` with other functions like `is_dir()` and `is_file()`, you can create a more robust file search mechanism. 

// Specify the directory to search in
$directory = 'path/to/directory';

// Get an array of all files in the directory
$files = glob($directory . '/*');

// Loop through each file and do something with it
foreach($files as $file) {
    if(is_file($file)) {
        echo "Found file: $file\n";
    } elseif(is_dir($file)) {
        echo "Found directory: $file\n";
    }
}
