What are the best practices for efficiently scanning through a large number of files in a directory using PHP?

When scanning through a large number of files in a directory using PHP, it is important to use efficient methods to avoid performance issues. One way to do this is by using the `glob` function to retrieve an array of file paths matching a specified pattern. Additionally, you can use the `scandir` function to get a list of files and directories in a specified directory. These functions help avoid memory overflows and allow for faster processing of files. 

// Using glob to scan through files in a directory
$files = glob('/path/to/directory/*');

foreach ($files as $file) {
    // Process each file
}

// Using scandir to scan through files in a directory
$files = scandir('/path/to/directory');

foreach ($files as $file) {
    // Process each file
}
