Note Submitter: chris ---- im just getting into php and was looking at these examples and asked one of my friends about example number 4 and why the $j += $i would be in there. he pointed out to me that it basically wouldnt do anything at all in there because it would be saving the value to $j which is never shown or printed in the example, altho i do see how it could be useful wouldnt something along the lines of for ($i = 0, $j = 1; $i < 10; $i += $j, print $i); do better to show that you can modify $i using $j and still get the same result of 1-10 being printed out, and then you dont just have $i going up because of the $i++ which is basically just like example one with extra random crap that is doing nothing
