How can I parse serialized data with PHP?

问题

This is an example of my serialized data:

a:10:{s:7:"contact";s:1:"1";s:19:"profile_affiliation";s:23:"University, Inc.";s:18:"profile_first_name";s:3:"Ben";s:22:"profile_street_address";s:19:"8718 Tot Ave. S.";s:12:"profile_city";s:6:"Mobile";s:13:"profile_state";s:2:"AL";s:15:"profile_country";s:3:"USA";s:15:"profile_zipcode";s:5:"36695";s:18:"profile_home_phone";s:10:"2599494420";s:17:"profile_last_name";s:6:"Powers";}

I want to be able to parse through it with PHP and display the values like so:

profile_first_name: Ben
profile_last_name: Powers
profile_state: AL

I know I need to unserialize it like so:

$unserialize = unserialize($data);

but I'm having trouble parsing the array with PHP. I keep getting "Invalid argument supplied for foreach()" errors and the incorrect array output.

This is what you are looking for

    <?php

    $serialized = 'a:10:{s:7:"contact";s:1:"1";s:19:"profile_affiliation";s:23:"University, Inc.";s:18:"profile_first_name";s:3:"Ben";s:22:"profile_street_address";s:19:"8718 Tot Ave. S.";s:12:"profile_city";s:6:"Mobile";s:13:"profile_state";s:2:"AL";s:15:"profile_country";s:3:"USA";s:15:"profile_zipcode";s:5:"36695";s:18:"profile_home_phone";s:10:"2599494420";s:17:"profile_last_name";s:6:"Powers";}';

    $fixed = preg_replace_callback(
        '/s:([0-9]+):"(.*?)";/',
        function ($matches) { return "s:".strlen($matches[2]).':"'.$matches[2].'";';     },
        $serialized
    );
    $original_array=unserialize($fixed);
    echo "<pre>";
    print_r($original_array);

You serailized string is corrupted so you need to repair it first then unserialize it

output

    Array
    (
        [contact] => 1
        [profile_affiliation] => University, Inc.
        [profile_first_name] => Ben
        [profile_street_address] => 8718 Tot Ave. S.
        [profile_city] => Mobile
        [profile_state] => AL
        [profile_country] => USA
        [profile_zipcode] => 36695
        [profile_home_phone] => 2599494420
        [profile_last_name] => Powers
    )
