What is the significance of the error message "PHP Warning: preg_replace(): The /e modifier is no longer supported, use preg_replace_callback" in PHP 7.2?

The error message "PHP Warning: preg_replace(): The /e modifier is no longer supported, use preg_replace_callback" indicates that the /e modifier in the preg_replace function is deprecated in PHP 7.2 and should be replaced with preg_replace_callback instead. To fix this issue, you need to update your preg_replace function calls to use preg_replace_callback.

// Before PHP 7.2
$output = preg_replace('/pattern/e', 'replacement', $input);

// After PHP 7.2
$output = preg_replace_callback('/pattern/', function($matches) {
    return 'replacement';
}, $input);
