Appending arrays If you have an array $a2 whose values you would like to append to an array $a1 then four methods you could use are listed below in order of increasing time. The last two methods took significantly more time than the first two. The most surprising lesson is that using the & incurs a time hit. foreach ($a2 as $elem) $a1[]=$elem; foreach ($a2 as &$elem) $a1[]=$elem; array_splice ($a1, count($a1), 0, $a2); $a1 = array_merge($a1, $a2); Csaba Gabor from Vienna ---- Manual Page -- http://www.php.net/manual/en/function.array-splice.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55790 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55790&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55790&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55790&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55790&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55790&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55790&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55790&report=yes Search -- http://master.php.net/manage/user-notes.php
