How can PHP be optimized for efficient directory scanning and file retrieval processes?

To optimize PHP for efficient directory scanning and file retrieval processes, you can use the `glob()` function instead of `scandir()` for faster performance. Additionally, you can limit the number of files or directories being scanned by specifying a pattern to filter out unnecessary files. This can help reduce the processing time and improve the overall efficiency of the operation. 

// Example code snippet using glob() function for efficient directory scanning and file retrieval
$files = glob('/path/to/directory/*.{jpg,png,gif}', GLOB_BRACE);
foreach ($files as $file) {
    echo $file . PHP_EOL;
}
