Serialize Question

ConceitoDigital

I have a serialized Array in my Session:


//Here the Session is the "string" serialized...
echo 'First: ' . $_SESSION['Word'] . '<br /><br />'; 

//I want to unserialize to $Word variable
//and not change the Session..
$Word = unserialize($_SESSION['Word']);

//Here its "array" normal unserialized
echo 'Second: '.$_SESSION['Word'];

This example returns:

 First: a:7:{s:15:"Nome da Empresa";s:9:"Loja Demo";s:3:"dia";s:2:"09";s:3:"mes";s:7:"Outubro";s:3:"ano";s:4:"2007";s:2:"ip";s:9:"127.0.0.1";s:7:"usuario";s:4:"Root";s:12:"tecla atalho";s:9:"ALT+SHIFT";}

Second: Array

I mean.. Doesnt "unserialize" just return the unserialized Value.. and not change the variable I sent?

Why is it doing that? and how to make to me still have "$_SESSION['Word']" serialized string... and just use the variable $Word when I need anything from that array?

Thanks

Ay, I see what you mean now....

Lemme see if i can reproduce it...

Nope, I can't do it.

<?php

session_start();

$tmp = array('Nome de Empresa', 'Loja Demo', 'dia', '09', 'mes', 'Outubro', 'ano', '2007', 'ip', '127.0.0.1', 'usuario', 'Root', 'teclatalho', 'ALT+SHIFT');

$_SESSION['Word'] = serialize($tmp);

echo 'First: ' . $_SESSION['Word'] . '<br /><br />';

$Word = unserialize($_SESSION['Word']);

echo 'Word: ' . print_r($Word, 1) . '<br /><br />';

echo 'Second: ' . $_SESSION['Word'];

?>

Gives me this output:

First: a:14:{i:0;s:15:"Nome de Empresa";i:1;s:9:"Loja Demo";i:2;s:3:"dia";i:3;s:2:"09";i:4;s:3:"mes";i:5;s:7:"Outubro";i:6;s:3:"ano";i:7;s:4:"2007";i:8;s:2:"ip";i:9;s:9:"127.0.0.1";i:10;s:7:"usuario";i:11;s:4:"Root";i:12;s:10:"teclatalho";i:13;s:9:"ALT+SHIFT";}

Word: Array
(
    [0] => Nome de Empresa
    [1] => Loja Demo
    [2] => dia
    [3] => 09
    [4] => mes
    [5] => Outubro
    [6] => ano
    [7] => 2007
    [8] => ip
    [9] => 127.0.0.1
    [10] => usuario
    [11] => Root
    [12] => teclatalho
    [13] => ALT+SHIFT
)


Second: a:14:{i:0;s:15:"Nome de Empresa";i:1;s:9:"Loja Demo";i:2;s:3:"dia";i:3;s:2:"09";i:4;s:3:"mes";i:5;s:7:"Outubro";i:6;s:3:"ano";i:7;s:4:"2007";i:8;s:2:"ip";i:9;s:9:"127.0.0.1";i:10;s:7:"usuario";i:11;s:4:"Root";i:12;s:10:"teclatalho";i:13;s:9:"ALT+SHIFT";}

Not sure what the difference is....

Not reproducible for me:

<?php
session_start();
header("Content-Type: text/plain");

$test = array('one', 'two', 'three');

$_SESSION['Word'] = serialize($test);

echo "First:\n\$_SESSION['Word']:\n";
var_dump($_SESSION['Word']);

$Word = unserialize($_SESSION['Word']);

echo "\nSecond:\n\$_SESSION['Word']:\n";
var_dump($_SESSION['Word']);
echo "\$Word:\n";
var_dump($Word);

Output:

First:
$_SESSION['Word']:
string(50) "a:3:{i:0;s:3:"one";i:1;s:3:"two";i:2;s:5:"three";}"

Second:
$_SESSION['Word']:
string(50) "a:3:{i:0;s:3:"one";i:1;s:3:"two";i:2;s:5:"three";}"
$Word:
array(3) {
  [0]=>
  string(3) "one"
  [1]=>
  string(3) "two"
  [2]=>
  string(5) "three"
}

Yes,

Oh!! Oh!! Is "register globals" on? If so, there's your issue 😉

With register globals on, if you "create" a variable of the same name as is in a global array (SESSION, COOKIE, POST, GET, _ENV) it will "overwrite" it.

NogDog

Do you have register_globals enabled? If so, then $arrPalavra may already be a reference to $_SESSION['arrPalavra'], so changing one will change the other.

haha, beat you to it Charles 😛 🙂

No problem, it's what we're here for.

Don't forget to mark this topic as resolved if it is.

Only because I took a little more time to explain why register_globals would have that effect, plus I had to look back at the image to see how to spell "$arrPalavra".

Ha!! Nevah!!

yeah, I went back and edited the post to explain about register globals, but whatever... the question got answered....
