note 75555 added to function.array-unique

The intersection won't work, since: intersection (['a','a','b','c'] , UNIQUE(['a','a','b','c']) ) = intersection (['a','a','b','c'], ['a','b','c']) = ['a','a','b','c'] While you only want ['a'] or ['a','a'] to be the result. The only solution is to write your own function. ---- Server IP: 194.109.193.76 Probable Submitter: 131.155.69.61 ---- Manual Page -- http://www.php.net/manual/en/function.array-unique.php Edit -- https://master.php.net/note/edit/75555 Del: integrated -- https://master.php.net/note/delete/75555/integrated Del: useless -- https://master.php.net/note/delete/75555/useless Del: bad code -- https://master.php.net/note/delete/75555/bad+code Del: spam -- https://master.php.net/note/delete/75555/spam Del: non-english -- https://master.php.net/note/delete/75555/non-english Del: in docs -- https://master.php.net/note/delete/75555/in+docs Del: other reasons-- https://master.php.net/note/delete/75555 Reject -- https://master.php.net/note/reject/75555 Search -- https://master.php.net/manage/user-notes.php
