In what scenarios would it be necessary to set a specific time frame for deleting dynamically generated HTML files in PHP?

When dealing with dynamically generated HTML files in PHP, it may be necessary to set a specific time frame for deleting these files to prevent them from accumulating and taking up unnecessary space on the server. This can be especially important for temporary files or cache files that are no longer needed after a certain period of time. By setting a time frame for deletion, you can ensure that your server remains clean and efficient.

// Set the time frame for deleting dynamically generated HTML files (e.g., 24 hours)
$timeFrame = 24 * 60 * 60; // 24 hours in seconds

// Specify the directory where the HTML files are stored
$directory = 'path/to/html/files/';

// Get the current time
$currentTime = time();

// Loop through the files in the directory
foreach(glob($directory . '*.html') as $file) {
    // Get the file's last modification time
    $fileTime = filemtime($file);
    
    // Check if the file is older than the specified time frame
    if ($currentTime - $fileTime >= $timeFrame) {
        // Delete the file
        unlink($file);
    }
}
