In what scenarios is it advisable to use PHP scripts for automated file renaming tasks, and when should alternative methods be considered?

When dealing with large batches of files that need to be renamed based on specific criteria or patterns, using PHP scripts can be a powerful and efficient way to automate the renaming process. PHP's flexibility and robust string manipulation functions make it well-suited for handling such tasks. However, for simpler renaming tasks or scenarios where performance is a concern, alternative methods like using command-line tools or dedicated file renaming software may be more appropriate.

<?php
// Specify the directory where the files are located
$directory = '/path/to/directory/';

// Open the directory
$dir = opendir($directory);

// Loop through each file in the directory
while (($file = readdir($dir)) !== false) {
    // Check if the file is a regular file
    if (is_file($directory . $file)) {
        // Perform the renaming logic here
        $newName = str_replace('old_pattern', 'new_pattern', $file);
        
        // Rename the file
        rename($directory . $file, $directory . $newName);
    }
}

// Close the directory
closedir($dir);
?>
