PHP Unserialize: Convert String to Data Structure

The unserialize function is used to convert a serialized string back into a PHP data structure. Its syntax is as follows:

mixed unserialize ( string $str )

Here, str is a serialized string. Unserialize converts this string back into the original PHP value.

For example,

$data = 'a:2:{s:4:"name";s:5:"Alice";s:3:"age";i:25;}';
$array = unserialize($data);
print_r($array);

The above code will output:

Array
(
    [name] => Alice
    [age] => 25
)
