outputs two here, as expected. PHP 4.3.2 over Win2000.
Maybe you're seeing a side-effect of a Not A Number magic value being
intelligently-evaluated.

RE: [PHP] if(NANC 0) - always evaluates TRUE...
Hi,
Never noticed it before...only after the linux box got updated to
v4.3.4...running the script against my v4.2.3 also outputs err 3
err4...version 4.0.6 outputs nothing as it should.
Odd...not sure where to start digging to figure this...in the meantime
I'll work it around like this:
$data = 'NANC';
if(is_numeric($data) $data 0)
{
die('Not OK');
}
print('OK');
Where do I file this for developers with some time on their hands to
look at?
Thanks,
Ivo

Interesting problem, one of the first legit oddities I've seen since
joining the list. Anyway, in addition to your workaround, casting the
variable as an int also appears to result in the desired behavior:
(int)NANC 0 == false

This all kind of begs the question of why you'd check if a string was less
than zero, anyhow, doesn't it???
