Why does pageLength not have a value?

Debugger code (debug.datatables.net):
Error messages shown: No error message, but it is not working
Description of problem: So I'm trying to get the number of results per row that should be shown by the user.

Here is my datatable variable:

var table = $('#example').DataTable( {
    "order": [[ 0, "desc" ]],
    "ajax": "./inc/database.php",
    "type": "GET",
    "lengthMenu": [ 10, 25, 50, 100 ],
    "pageLength": 10,
    "columns": [
        { "data": "id" },
        { "data": "download" },
        { "data": "recorded" },
        { "data": "expires" },
        { "data": "server" },
        { "data": "map" },
        { "data": "t" },
        { "data": "ct" },
        { "data": "roundtime" },
        { "data": "winner" },
        { "data": "file", "bVisible": false }
    ],
    "oLanguage": {
        "sLengthMenu": "Show _MENU_ results per page",
        "sSearch": "Search from all columns: "
    }
} );

And then I'm trying to print out the amount of rows the client selected per page with PHP:

echo isset($_GET["pageLength"]) ? $_GET["pageLength"] : "No value";

But it prints "No value" even tho I set the "pageLength" value. Why?

$_GET["pageLength"]

pageLength is not accessible that way.
You want page.len().

How can I access that in PHP then?

I'm not clear why you want to access the page length on the server? Are you intending to use serverSide? That needs it, but for plain ajax, you just send back all data for the table,
