Here's a sick idea. When a function returns no value, if you assign its return value to a
variable that variable will be unset. So instead of returning -1 on error just return with no
value.
For example,
function myfunc($myvar) {
if ($myvar == "abc")
return(1);
if ($myvar == "xyz")
return(2);
return;
}
$abc = myfunc("def");
if (isset($abc))
echo("a-ok");
else
echo("oops");
