If $NumFixes = 2, then the following lines of code:

echo("Num fixes: [" . $NumFixes - 1 . "]\n");
echo("Num fixes: [" . ($NumFixes - 1) . "]\n");

Produce this output:

-1]
Num fixes: [1]

I assumed that the echo function, at least, worked the same way in PHP as it does in C.  C doesn't have a concatenation operator though, and maybe this is as intended.  (If it's not, then please fix it, because although the second line of code is "cleaner", the first line should work *anyway*.)
