PHP Unserialize: Convert Strings to PHP Values

The PHP unserialize function is used to convert serialized data stored in a string into PHP values. Serialization is the process of converting PHP values into strings, while deserialization is the process of converting these strings back into the original PHP values. The unserialize() function plays a role in this process by restoring the original PHP values from the serialized data in the string, which includes information about the data types and values used during serialization. This process is commonly used for storing and passing complex data structures, such as objects or arrays.
