note 81182 added to control-structures.for

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 ---- Server IP: 208.69.120.35 Probable Submitter: 65.111.208.82 ---- Manual Page -- http://www.php.net/manual/en/control-structures.for.php Edit -- https://master.php.net/note/edit/81182 Del: integrated -- https://master.php.net/note/delete/81182/integrated Del: useless -- https://master.php.net/note/delete/81182/useless Del: bad code -- https://master.php.net/note/delete/81182/bad+code Del: spam -- https://master.php.net/note/delete/81182/spam Del: non-english -- https://master.php.net/note/delete/81182/non-english Del: in docs -- https://master.php.net/note/delete/81182/in+docs Del: other reasons-- https://master.php.net/note/delete/81182 Reject -- https://master.php.net/note/reject/81182 Search -- https://master.php.net/manage/user-notes.php
