Is there such a thing?

for eg

$var = -5;
echo thefunction($var); // should be 0


$var = 5;
echo thefunction($var); // should be 5

Try max($var,0), which will have the desired effect. See the manual page for more information.

Not built-in but, here you have:

function thefunction($var){
   return ($var < 0 ? 0 : $var);
}

Hope this helps
