Author：Eve Cole Update Time：2024-12-28 10:12:01

The unserialize() function is used to deserialize the object or array serialized by the serialize() function and return the original object structure.

PHP version requirements: PHP 4, PHP 5, PHP 7

grammar

 mixed unserialize (string $str)

Parameter description:

$str: Serialized string.

return value

What is returned is the converted value, which can be integer, float, string, array or object.

If the passed string is not deserializable, FALSE is returned and an E_NOTICE is generated.

Example

<?php $str = ' a:3:{i:0;s:6:"Google";i:1;s:6:"Codercto";i:2;s:8:"Facebook";} ' ; $unserialized_data = unserialize ( $str ) ; print_r ( $unserialized_data ) ; ?>

The output is:

 Array( [0] => Google [1] => Codercto [2] => Facebook)
