在PHP中的会话变量中添加变量？

Question

如何将变量添加到$_SESSION？

$product = 0;
$_SESSION['product_number'.$product.''] = true;

它不起作用.

Answer 1

您需要确保使用了session_start() ;

page1.php中

<?php
session_start();

$product = 0;
$_SESSION['product_number'.$product] = true;

?>

使page2.php

<?php
session_start();
$product = 0;
if ($_SESSION['product_number'.$product]) echo 'Session variable was set!';
else echo 'It was not!';
?>

Answer 2

这可能对你有用:

<?
session_start();
$product = 0;
$_SESSION['product_number'] = $product;
?>
