Cleaning $_GET['id']

[JonD]

I get the variable from the url to execute in queries. 'id' **** always be a number so whats the best way to clean it?

will intval do or is there sum sort of regular expressions i can do to redirect the page if the value of id is not a number?

Thx

Should this work?

function validateInt($number)
{
	if (is_numeric($number))
		return intval($number);		
	return;
}

but if u use intval and 'id' is sumthing like: '342thisisnotanumber' it will return 342. It would still be nice if I knew this wudnt be accepted.

I think rob wins, casting **** work fine.
