Can I use array_push on a SESSION array in php?
提问by zeckdude
I have an array that I want on multiple pages, so I made it a SESSION array. I want to add a series of names and then on another page, I want to be able to use a foreach loop to echo out all the names in that array.
我有一个需要在多个页面上显示的数组，因此我将其设为 SESSION 数组。我想添加一系列名称，然后在另一个页面上，我希望能够使用 foreach 循环来回显该数组中的所有名称。
This is the session:
这是会议：
$_SESSION['names']
I want to add a series of names to that array using array_push like this:
我想使用 array_push 向该数组添加一系列名称，如下所示：
array_push($_SESSION['names'],$name);
I am getting this error:
我收到此错误：
array_push() [function.array-push]: First argument should be an array
array_push() [function.array-push]：第一个参数应该是一个数组
Can I use array_push to put multiple values into that array? Or perhaps there is a better, more efficient way of doing what I am trying to achieve?
我可以使用 array_push 将多个值放入该数组吗？或者也许有更好，更有效的方式来做我想要实现的目标？

Yes, you can. But First argument should be an array.
是的你可以。但第一个参数应该是一个数组。
So, you must do it this way
所以，你必须这样做
$_SESSION['names'] = array();
array_push($_SESSION['names'],$name);
Personally I never use array_push as I see no sense in this function. And I just use
我个人从不使用 array_push，因为我认为这个函数没有意义。我只是用
$_SESSION['names'][] = $name;

Try this, it's going to work :
试试这个，它会起作用：
session_start();
if(!isset($_POST["submit"]))
{
$_SESSION["abc"] = array("C", "C++", "JAVA", "C#", "PHP");
}
if(isset($_POST["submit"]))
{
$aa = $_POST['text1'];
array_push($_SESSION["abc"], $aa);
foreach($_SESSION["abc"] as $key => $val)
{
echo $val;
}
}
