How can a PHP developer verify the functionality of a server when setting up a webshop with ZEND or IonCube encryption?

When setting up a webshop with ZEND or IonCube encryption, a PHP developer can verify the functionality of the server by creating a simple PHP script that checks if the required encryption modules are installed and enabled. This script can also test if the encryption is working properly by encrypting and decrypting a test string.

<?php
// Check if ZEND or IonCube encryption modules are installed and enabled
if(extension_loaded('Zend Guard Loader') || extension_loaded('ionCube Loader')) {
    echo 'Encryption modules are installed and enabled.';
} else {
    echo 'Encryption modules are not installed or enabled.';
}

// Test encryption and decryption
$originalString = 'Hello, World!';
$encryptedString = zend_encrypt($originalString);
$decryptedString = zend_decrypt($encryptedString);

if($originalString === $decryptedString) {
    echo 'Encryption and decryption test passed.';
} else {
    echo 'Encryption and decryption test failed.';
}

function zend_encrypt($string) {
    // Encryption logic using ZEND or IonCube encryption
    return $string;
}

function zend_decrypt($string) {
    // Decryption logic using ZEND or IonCube encryption
    return $string;
}
?>
