note 85331 added to function.range

foreach(range()) whilst efficiant in other languages, such as python, it is not (compared to a for) in php*. php is a C-inspired language and thus for is entirely in-keeping with the lanuage aethetic to use it <?php //efficiant for($i = $start; $i < $end; $i+=$step) { //do something with array } //inefficiant foreach(range($start, $end, $step) as $i) { //do something with array } ?> That the officiant documentation doesnt mention the for loop is strange. Note however, that in PHP5 foreach is faster than for when iterating without incrementing a variable. * My tests using microtime and 100 000 iterations consistently (~10 times) show that for is 4x faster than foreach(range()). ---- Server IP: 64.71.164.2 Probable Submitter: 84.19.108.52 ---- Manual Page -- http://www.php.net/manual/en/function.range.php Edit -- https://master.php.net/note/edit/85331 Del: integrated -- https://master.php.net/note/delete/85331/integrated Del: useless -- https://master.php.net/note/delete/85331/useless Del: bad code -- https://master.php.net/note/delete/85331/bad+code Del: spam -- https://master.php.net/note/delete/85331/spam Del: non-english -- https://master.php.net/note/delete/85331/non-english Del: in docs -- https://master.php.net/note/delete/85331/in+docs Del: other reasons-- https://master.php.net/note/delete/85331 Reject -- https://master.php.net/note/reject/85331 Search -- https://master.php.net/manage/user-notes.php
