Question

i want to access a certain node of my xml with given id which i’m getting from a post parameter like this:

$id = $_POST['id'];
$xml->content[$id];

unfortunately it doesn’t work – returns empty. seems like because $id is problably of type string, not integer.
i tried to convert it like:

$id = int $id;

which gave me this error:

syntax error, unexpected T_VARIABLE

any ideas how to fix it?
thanks

Answer 1

You should use

$id = (int) $id;

instead of $id = int $id;
