Find whether an int is positive or negative

[ballhogjoni]

How can I find out if a number is positive or negative?

<?php
$int = -19;
if ($int < 0) {
    echo "neg";
}
else {
   echo "pos";
}

That doesn't exactly account for if $int doesn't exist, though.  If $int doesn't exist, it will evaluate true, or 0, and echo "pos".  You'd have to wrap an if ($int) or if (isset($int)) or something around that.

 

edited for clarification.  I posted an example similar to darkwater's and based my explanation off it.  But since he posted an example, I changed it to base it off of his example.
