How can one ensure that an array remains accessible and unchanged in different parts of a PHP script?

To ensure that an array remains accessible and unchanged in different parts of a PHP script, you can use the `$_SESSION` superglobal array to store the array values. This way, the array values will persist across different parts of the script as long as the session is active. You can access and modify the array values by setting and getting them from the `$_SESSION` array. 

session_start();

// Initialize the array
$_SESSION['myArray'] = ['value1', 'value2', 'value3'];

// Access the array values
$myArray = $_SESSION['myArray'];

// Modify the array values
$myArray[] = 'new value';

// Update the array in the session
$_SESSION['myArray'] = $myArray;
