在PHP中使用反序列化时出错？

Question

$info='a:1:{s:10:"2G Network";s:22:"GSM 900 / 1800 / 1900 ";}';
$info1 = unserialize($info);
print_r($info1);

When run code in firebug get error:

Notice: unserialize() [<a href='function.unserialize'>function.unserialize</a>]: Error at offset 0 of 65 bytes in...

How to fix it ?

Answer 1

$info='a:38:{s:10:"2G Network";s:22:"GSM 900 / 1800 / 1900 ";}'; is not properly serialized.

The format for an array is as follows:

a: number of items :{ collection of elements };

You one element in your array (2G Network => GSM 900 / 1800 / 1900). All the rest is fine, and the following unserializes properly:

a:1:{s:10:"2G Network";s:22:"GSM 900 / 1800 / 1900 ";}

Answer 2

use utf8_encode and utf8_decode..
like..

$str = utf8_encode($str); 

$str= unserialize($str); 

$str= utf8_decode($str);  

Answer 3

I think this one is help to resolve your problem :

<?php

$info = serialize(array('2G Network','GSM 900 / 1800 / 1900'));
(or)
$info='a:1:{s:10:"2G Network";s:22:"GSM 900 / 1800 / 1900 ";}';

$info1 = unserialize($info);
// Show the unserialized data;
print_r($info1);
?>
