How to push a new array value into a PHP session array?
提问by Keith Donegan
I have the following rough code:
我有以下粗略的代码：
$_SESSION['ids'] = array('strawberry', 'banana', 'apple');
and want to insert some values on a condition (when a person clicks a certain button etc).
并且想要在条件下插入一些值（当一个人点击某个按钮等时）。
array_push($_SESSION['ids'], 'orange');
but it doesn't seem to work?
但它似乎不起作用？
The original array with 'strawberry', 'banana', 'apple' are there when I view a var_dump'edview of it, but 'orange' is not there?
当我查看它的var_dump视图时，原始数组包含“草莓”、“香蕉”、“苹果” ，但“橙色”不存在？

I have tested the following code on PHP 5.4:
我已经在 PHP 5.4 上测试了以下代码：
session_start();
$_SESSION['ids'] = array('strawberry', 'banana', 'apple');
array_push($_SESSION['ids'], 'orange');
var_dump($_SESSION['ids']);
The output is as follows:
输出如下：
array(1) { ["ids"]=> array(4) { [0]=> string(10) "strawberry" [1]=> string(6) "banana" [2]=> string(5) "apple" [3]=> string(6) "orange" } }

The code you have used should perfectly work even without starting the session. Still giving you the sequence of the statements.
即使不启动会话，您使用的代码也应该可以完美运行。仍然给你陈述的顺序。
code
代码
<?php
$_SESSION['ids'] = array('strawberry', 'banana', 'apple');
array_push($_SESSION['ids'], 'mango');
var_dump($_SESSION);
?>
O/P
开/关
array(1) { ["ids"]=> array(4) { [0]=> string(10) "strawberry" [1]=> string(6) "banana" [2]=> string(5) "apple" [3]=> string(5) "mango" } }

Simple, take an array element. In the following code I made a session element as array element. Using array_push we can add elements. And don't forget to start session.
简单，取一个数组元素。在下面的代码中，我将会话元素作为数组元素。使用 array_push 我们可以添加元素。并且不要忘记开始会话。
$_SESSION['total_elements']=array();
array_push($_SESSION['total_elements'], $_POST["username"]);

As mentioned in the comments, you can push something to the $_SESSION['ids']array like:
正如评论中提到的，您可以将某些内容推送到$_SESSION['ids']数组，例如：
$_SESSION['ids'][] = 'orange';

$_SESSIONis not a super global like other variables. A quick tour on php session handling is given at here, basically you got to call session_start to initialize your session before the array is properly accessible for subsequent writes / reads.
$_SESSION不像其他变量那样是超级全局变量。此处提供了有关 php 会话处理的快速浏览，基本上您必须调用 session_start 来初始化您的会话，然后才能正确访问数组以进行后续写入/读取。

You can do this :
你可以这样做 ：
$_SESSION['ids'] [] = 'orange';
