Unserialize

(PHP3 >= 3.0.5, PHP4)

Unserialize---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Create PHP values from stored values

Syntax: Mixed unserialize (String str)

Description:

Unserialize () takes a serialized variable (reference serialize ()) and converts it back to the value of PHP, returns the converted value, and can be integer, double, string, array, object. If an object has a serialized, its method is not saved in the returned value.

Example:

<?php

Here, we use Unserialize () to load sessions data from a database

Into $session _data. This example complements the one described

With Serialize ().

$conn = Odbc_connect ("WebDB", "PHP", "chicken");

$stmt = Odbc_prepare ($conn, "SELECT data from sessions WHERE ID =?");

$sqldata = Array ($PHP _auth_user);

if (!odbc_execute ($stmt & $sqldata) | |!odbc_fetch_into ($STMT, & $tmp)) {

If the execute or fetch fails, initialize to empty array

$session _data = Array ();

else {

We should now have the serialized data in $tmp [0].

$session _data = unserialize ($tmp [0]);

if (!is_array ($session _data)) {

Something went wrong, initialize to empty array

$session _data = Array ();

}

}
