php - 数组不会保存到 SESSION PHP

Question

我有以下代码。

$getPoetry['poet'] = $_SESSION[$member]['filters']['newspaper'] = array(
    '$in' => $allFollowing
);

$getPoetry['poet'] 里面有完整的数组，而 $_SESSION[$member]['filters']['newspaper'] 没有。

可能是什么问题？

当我打印数组 $_SESSION[$member] 存在但它是一个空数组的键

Answer 1

试试这个

<?php   
    session_start();

    // create an array
    $my_array=array('cat', 'dog', 'mouse', 'bird', 'crocodile', 'wombat', 'koala', 'kangaroo');

    // put the array in a session variable
    $_SESSION['animals']=$my_array;

    // a little message to say we have done it
    echo 'Putting array into a session variable';

    // loop through the session array with foreach
    foreach($_SESSION['animals'] as $key=>$value)
        {
        // and print out the values
        echo 'The value of $_SESSION['."'".$key."'".'] is '."'".$value."'".' <br />';
        }
    ?>

您的示例我为您使用过的变量赋予了一些价值

<?php
session_start();
$member = 'new';
$allFollowing = 'follower';
$getPoetry['poet'] = $_SESSION[$member]['filters']['newspaper'] = array('$in' => $allFollowing);
print_r($_SESSION[$member]['filters']['newspaper']);
print_r($getPoetry);
?>

@Yogesh Suthar 情况下，他错过了密钥，并且 0 也不应该出现在会话中的第一个密钥检查中

<?php   
session_start();
$abcd = $_SESSION['test']['filters']['newspaper'] = array('test'=>"abcd");
print_r($_SESSION['test']['filters']['newspaper']);
print_r($abcd);
?>

Answer 2

它工作正常。我认为您尚未session_start();在页面顶部开始会话使用

session_start();

$abcd = $_SESSION[0]['filters']['newspaper'] = array("abcd");

print_r($_SESSION[0]['filters']['newspaper']);
print_r($abcd);

输出如下

Array ( [0] => abcd ) Array ( [0] => abcd )
