$_SESSION

$HTTP_SESSION_VARS [deprecated]

$_SESSION -- $HTTP_SESSION_VARS [deprecated] — Session variables

Descrierea

An associative array containing session variables available to the current script. See the Session functions documentation for more information on how this is used.

$HTTP_SESSION_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_SESSION_VARS and $_SESSION are different variables and that PHP handles them as such)

Istoria schimbărilor

Versiunea	Descriere
4.1.0	Introduced `$_SESSION` that the deprecated `$HTTP_SESSION_VARS`.

Note

Notă: Aceasta este o variabilă 'superglobală', sau globală automată. Aceasta pur şi simplu înseamnă că ea este disponibilă în toate circumstanţele pe parcursul script-ului. Nu este nevoie de a scrie global $variable; pentru a o accesa din funcţii sau metode.

Unlike a real PHP array, $_SESSION keys at the root level must be valid variable names.



<?php 

$_SESSION[1][1] = 'cake'; // fails



$_SESSION['v1'][1] = 'cake'; // works

?>



I imagine this is an internal limitation having to do with the legacy function session_register(), where the registered global var must similarly have a valid name.

You may have trouble if you use '|' in the key:



$_SESSION["foo|bar"] = "fuzzy";



This does not work for me. I think it's because the serialisation of session object is using this char so the server reset your session when it cannot read it.



To make it work I replaced '|' by '_'.
