How can the glob function be effectively used in PHP to iterate through files in a directory?

To iterate through files in a directory in PHP, the glob function can be effectively used. Glob allows you to retrieve an array of file names that match a specified pattern, which can then be looped through to process each file. By using glob with a wildcard pattern, you can easily retrieve all files in a directory for further processing. 

$files = glob('/path/to/directory/*');
foreach ($files as $file) {
    echo $file . PHP_EOL;
}
