How can PHP be used to extract specific information from file names with a non-standard format for further processing?

When dealing with file names in a non-standard format, regular expressions can be used in PHP to extract specific information for further processing. By defining a pattern that matches the desired information within the file name, we can use functions like preg_match() to extract and use that information in our code. 

$filename = "file_name_date12345.csv";
$pattern = '/^file_name_(.*?)\.csv$/';
if (preg_match($pattern, $filename, $matches)) {
    $date = $matches[1];
    // Further processing using the extracted $date
    echo "Date extracted from file name: " . $date;
} else {
    echo "No match found";
}
