What are some best practices for handling file modification times in PHP scripts?

When working with file modification times in PHP scripts, it is important to ensure that you are handling them accurately to avoid any discrepancies in your application. One common best practice is to use the `filemtime()` function to retrieve the last modification time of a file and then format it using `date()` function for better readability and consistency. 

// Get the last modification time of a file
$lastModifiedTime = filemtime('example.txt');

// Format the modification time using date function
$formattedTime = date('Y-m-d H:i:s', $lastModifiedTime);

echo "Last modified time: " . $formattedTime;
