How can one effectively replace preg_replace with preg_replace_callback in PHP code?

To effectively replace preg_replace with preg_replace_callback in PHP code, you can use preg_replace_callback to define a callback function that will be called for each match found by the regular expression pattern. This allows for more flexibility and control over the replacement process compared to preg_replace.

// Original preg_replace usage
$new_string = preg_replace('/pattern/', 'replacement', $original_string);

// Updated code using preg_replace_callback
$new_string = preg_replace_callback('/pattern/', function($match) {
    // Custom logic to determine replacement based on $match
    return 'replacement';
}, $original_string);
