[Resolved] settype: value changed to zero

[beckstei]

I have a function which returns a string, which reads as a number. The string is the browser window width. I'm trying to use settype after the function call to change the string into an integer so I can use it to do calculations for div layouts.

A call to settype($width, "integer") changes the value of $width to 0;

e.g.

echo "after settype width = $width";

after settype width = 0;

I don't know why this is happening. If I try to reset the type via
(integer) $width, the value of $width also becomes 0.

Any pointers would be appreciated.

Thanks

echo '-'.$width.'-'.strlen($width);

do this beofre changing the type and post the result

The following:

echo '-'.$width.'-'.strlen($width);

yields:
-1155-56

So, php is seeing the string which I'm passing to the javascript function and not the value which is being returned?
