note 52909 added to function.in-array

Further to my previous post this may prove to be more efficient by eliminating the need for array_flip() on each iteration. $distinct_words = array(); foreach ($article as $word) { if (!isset($distinct_words[$word])) $distinct_words[$word] = count($distinct_words); } $distinct_words = array_flip($distinct_words); ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52909 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52909&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52909&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52909&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52909&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52909&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52909&report=yes Search -- http://master.php.net/manage/user-notes.php
