serialize() and unserialize()?
serialize() converts a PHP data structure (like an array or object) into a string that can be saved or transferred easily.
unserialize() takes that storable/transferrable string and converts it back into the original PHP data structure.
Commonly, you might store serialized data in a file or database, or send it across a network (although JSON is often used these days for broader compatibility).
Note: Using unserialize() on untrusted data can be dangerous because it may allow malicious code injection. Consider safer alternatives like JSON, or at least use strict options such as allowed_classes to mitigate risks.
