No need for separate tools, gcc -Wall issues an informative warning.
And you do compile with -Wall, right?

If you are not comfortable with the above problem, consider this:

if ($a = $b) { ...
if ($a == $b) { ...
if ($a === $b) { ...

All three are legal in PHP and have different meaning.
Now *that* is funny. ;-)

BTW - if just parentheses in C are problematic for anybody, I recommend 
some Lisp or Scheme exercise for better perspective... :-)
