note 17124 added to function.array-unique

array_unique() can remove element which is not duplicated. if you explode() some paragraph with newline and do array_unique(), about 20 letter of each element to be compared for duplication judge, I think. so, a[0] = "THE SAME LETTERS BEFORE and something" a[1] = "THE SAME LETTERS BEFORE and anything" array_unique( a ) returns a with only [0] element. -- http://www.php.net/manual/en/function.array-unique.php http://master.php.net/manage/user-notes.php?action=edit+17124 http://master.php.net/manage/user-notes.php?action=delete+17124 http://master.php.net/manage/user-notes.php?action=reject+17124
