Okay, it's REALLY hard to see how all three tests could return TRUE...
But what is IN $variable and $constant?

An alternative not yet mentioned:
if (isset($variable)){
switch (TRUE){
case ($variable < $constant):
break;
case ($variable > $constant):
break;
case ($variable == $constant):
break;
}
}
else{
}
