What is the use of serialize and unserialize in php
The serialize () function serializes an object or array and returns a string.
After serializing the object, the serialize () function can easily pass it to other places where it is needed, and its type and structure will not change.
If you want to change the serialized string back to the value of PHP, use unserialize ().
The unserialize () function is used to deserialize the object or array serialized by the serialize () function and return the original object structure.
The syntax is as follows:
String serialize (mixed $value) mixed unserialize (string $str)
$value: the object or array to serialize.
Str: the serialized string.
Examples are as follows:
