how to pass an array in GET in PHP?

Question

$idArray = array(1,2,3,4);

can I write this line in HTML?

Answer 1

In the particular case you mentioned, I would implode the array to a string and then explode it when you post the form.

$str = rawurlencode(implode(",",$idArray));

and then on the post processing:

 $idArray = explode(",",rawurldecode($_POST['arr']));
