I think you guys are missing something: he wrote it with single equals
signs on purpose. He was demonstrating how the one with the constant to
the right of the assignment operator is a valid statement... and that
putting the constant first will aid you in finding such mistakes.
if("constant" = $variable){} // bombs, and lets you know right away you
missed an =
if($variable = "constant"){} // assigns rather than compares, but
nonetheless is valid code
To quote Colin: "As I very humorously hinted at in a earlier mail on
this thread, it is a very, very good idea to get into the habit of
putting constants *first* in if/while/etc statements." So, I'm sure he
is well familiar with this "method we're speaking of." :)
