What are the differences in usage between mcrypt and openssl functions in PHP for data decryption?

When decrypting data in PHP, it is important to choose the appropriate encryption functions. The mcrypt functions have been deprecated in PHP 7.1 and removed in PHP 7.2, so it is recommended to use the openssl functions for data decryption. OpenSSL is a more secure and actively maintained encryption library in PHP. 

// Example code snippet using openssl functions for data decryption
$encryptedData = "encrypted data here";
$encryptionKey = "encryption key here";

$decryptedData = openssl_decrypt($encryptedData, 'AES-256-CBC', $encryptionKey, 0, substr($encryptionKey, 0, 16));

echo $decryptedData;
