Sorry if I'm missing something, there's a lot of replies after my first
post on this thread.
Is there something wrong with the floor() approach? I liked the regex
solution but isn't it more expensive and more verbose than just doing a
well commented is_numeric plus floor/ceil math?
Just trying

All responses in this thread have been very nice; but you could also try
a much simpler 2-step check:
1. is_numeric
2. if true check if

I suppose one could try something like this:
if (is_string($val) $val === (string)(int)$val)
If $val is an integer masquerading as a string, it should be identical to
the original string when cast back to a string, shouldn't it? (I can't try
it right now.)

You could use is_numeric for that, though it also accepts floats.
Something like if (is_numeric($var) $var == floor($var)) will do the
trick. I don't know if there's a better (more elegant) way.
