Sadly, while '===' is the quick fix, you then have to litter your code with type casting operators if you're comparing numbers, particularly those sourced from, say, a database, where everything is returned as a string. Or from GET or POST data, where everything is a string.

This tripped me up when I was trying to compare two numbers, one of which was the result of a COUNT query via PDO. Of course, that COUNT result was a string.

I suppose if you worked entirely with strings it's alright. Or it wouldn't be so bad if you could make the reasonable assumption that functions returned appropriately typed data.
