What are the best practices for efficiently updating values within an array stored in a PHP file without losing other key-value pairs?

When updating values within an array stored in a PHP file, it's important to read the file, update the specific value, and then write the updated array back to the file without losing other key-value pairs. One way to achieve this is by using PHP's file handling functions to read, modify, and write the array data. 

// Read the contents of the PHP file
$data = include 'data.php';

// Update the specific value within the array
$data['key'] = 'new value';

// Write the updated array back to the PHP file
file_put_contents('data.php', '<?php return ' . var_export($data, true) . ';');
