In PHP, how do I deserialize strings with PHP 8+ features?

In PHP 8 and later, deserializing strings can be done securely and efficiently using the `unserialize()` function. To enhance security, consider using the `allowed_classes` parameter to prevent malicious objects from being deserialized.

<?php // Example of deserializing a string in PHP 8+ $data = 'O:8:"MyClass":1:{s:3:"foo";s:3:"bar";}'; class MyClass { public $foo; } // Using allowed_classes to prevent deserialization of arbitrary objects $object = unserialize($data, ['allowed_classes' => ['MyClass']]); // Display the result echo $object->foo; // Outputs: bar ?>
