note 111025 added to function.array-diff

You should consider that if the first array is empty then the result is empty, which is not becoming clear at first if you read the return value description: "Returns an array containing all the entries from array1 that are not present in any of the other arrays." Consider checking if array1 is empty before using this function. ---- Server IP: 69.147.83.199 Probable Submitter: 93.152.158.160 ---- Manual Page -- http://php.net/manual/en/function.array-diff.php Edit -- https://master.php.net/note/edit/111025 Del: integrated -- https://master.php.net/note/delete/111025/integrated Del: useless -- https://master.php.net/note/delete/111025/useless Del: bad code -- https://master.php.net/note/delete/111025/bad+code Del: spam -- https://master.php.net/note/delete/111025/spam Del: non-english -- https://master.php.net/note/delete/111025/non-english Del: in docs -- https://master.php.net/note/delete/111025/in+docs Del: other reasons-- https://master.php.net/note/delete/111025 Reject -- https://master.php.net/note/reject/111025 Search -- https://master.php.net/manage/user-notes.php
