How can the glob() function be utilized to efficiently scan directories for specific file types in PHP?

To efficiently scan directories for specific file types in PHP, the glob() function can be utilized with a wildcard pattern to match files based on their extension. By specifying the directory path and the file extension pattern, glob() can return an array of file paths that match the criteria, making it easy to iterate over and process the files. 

$directory = '/path/to/directory/';
$fileType = '*.txt'; // Specify the file type to search for, e.g., all .txt files

$files = glob($directory . $fileType);

foreach ($files as $file) {
    // Process each file as needed
    echo $file . PHP_EOL;
}
