$GET['id'] is 19, (int) $GET['id'] is 0 ??? in internet explorer 11

Question

I am trying to typecast a GET variable to int in internet explorer 11 (only) without success

URL ...&project_id=19

$tt= $_GET['project_id'] ; is 19 in debugger, as expected

$tt= (int) $_GET['project_id'] ; is 0

strlen($tt) is 2

mb_str_encoding($tt) is ASCII

In FF, the typecast works fine, same in older internet explorer.

anyone has ideas what is going on?

This has nothing to do with browsers. I'd also recommend you use `intval` instead of casting to an int. — Mr. Llama, Jan 20 '14 at 22:45

I suggest not using cast. Instead use intval It's a bit slower than casting , see benchmark, but in my experience safer.

"but in my experience safer" --- could you please elaborate? What would you say if I tell you they both use the same code internally? – zerkms Jan 20 '14 at 23:29

oneneeds to reconvert from ASCII to UTF-8.

the following works:

$tt= (int) mb_convert_encoding($_GET['project_id'], 'UTF-8' );

`19` is an ASCII safe string. In UTF-8 it's encoded with **exactly the same** bytes. – zerkms Jan 20 '14 at 23:14
