I have a session called $_SESSION['data']

And I have a text input called 'lengtezijde'

I already used foreach on the session:

foreach ($_SESSION['data'] as $key => $data);

And if I want to use my input from lengtezijde, I tried it like this:

echo $_SESSION['data'][$_GET['key'];

but then it is an array and I want the input value.

How do I go a layer deeper in the array to use the value?

Please try this inside the foreach loop:

echo $data['lengtezijde'];

or

echo $_SESSION['data'][$key]['lengtezijde'];

We have seen $key will have indexing value 0.

Note: as looping on session data you will get $data value as when print $data:

Array ( [hoogte] => 1 [kleur] => 1 [lengtezijde] => 800 [toevoegen] => toevoegen )

So you can get directly the value of lengtezijde by using as :

$data['lengtezijde']; inside the foreach loop.

Try this ....

echo $_SESSION['data'][$key]['lengtezijde'];

It is not clear how you set the value of the array. If you set the array value in the for-loop like this:

foreach ($_SESSION['data'] as $key => $data);

    $data['lengtezijde'] = "some value";

Then to get the value you must do something like this:

$key = $_GET['key']; //or the key to the index you want

echo $_SESSION['data'][$key]['lengtezijde'];
