$_POST contains array with string, bind it to variable

Question

A var_dump of $_POST gives the following result:

array(1) {
    ["postID"]=>
        array(1) {
            [0]=>
            string(2) "76"
        }
}

I want to bind the data from position [0] -> "76" to a variable called $id. What is the correct way to handle this?

Thanks in advance!

Just access the array element and assign it to your variable. — Rizier123, May 06 '17 at 19:16
I tried that @Pharaoh but then I get the error Notice: Undefined offset: 0 and a var_dump of $id would give me NULL — Moya, May 06 '17 at 19:18
Oh, I misread the code. It's `$id = $_POST['postID'][0]`. I also indented your code so it's obvious now. — Imanuel, May 06 '17 at 19:20

You can access this value doing:

$id = $_POST['postID'][0];

Thanks! I have a follow up question, If you don't mind. Is there a way to trim the data stored in the variable so that it only reads 76 instead of string(2) "76"? – Moya May 06 '17 at 19:23

You see `string(2) "76"` because you are doing var_dump, var_dump is explaining you the value is a string of 2 characters which is "76". The actual value is just "76", you can test it doing `echo $_POST['postID'][0];` – Agu Dondo May 06 '17 at 19:25
Thanks for the clarification Agu Dondo! – Moya May 06 '17 at 19:27
