Comments:
The "==" has higher precedence than does "xor," so evaluating left to right we
have:
$h == 4 xor $i == 5 xor $j == 6
or:
true xor true xor true
then:
false xor true
and finally:
true
which is true, which is expected behavior. Use parens to group the exressions to get the results
you are looking for.

<?php
$h = 4; $i =5, $j=6;
if ($h == 4 xor $i == 5 xor $j == 6) {
echo ("The condition is true");
}
else {
echo ("The condition is false");
}
?>
When i run it, i obtain The condition is true...
Im running PHP as Apache module.
