What are the potential consequences of not backing up the PHP.ini file before making changes?

If the PHP.ini file is not backed up before making changes, there is a risk of losing important configurations or causing errors that could potentially break the website or application. To avoid these consequences, it is best practice to always create a backup of the PHP.ini file before making any modifications. 

// Example of backing up the PHP.ini file before making changes
$original_php_ini = '/path/to/php.ini';
$backup_php_ini = '/path/to/backup/php.ini';

// Copy the original PHP.ini file to create a backup
copy($original_php_ini, $backup_php_ini);

// Make changes to the PHP.ini file
// Your code for making changes here
