note 106328 added to language.types.array

This is a simple solution for taking previous and next items, even if we are at the ends of the array. <?php $current_key; // the key of the item we want to search from if (isset($array[$current_key+1])) { $array_next = $array[$current_key+1]; // get the next item if there is } else { $array_next = $array[0]; // if not take the first (this means this is the end of the array) } if (isset($array[$current_key-1])) { $array_prev = $array[$current_key-1]; // get the previous item if there is } else { $array_prev = $array[count($array)-1]; // if not take the last item (this means this is the beginning of the array) } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 87.126.0.28 ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- https://master.php.net/note/edit/106328 Del: integrated -- https://master.php.net/note/delete/106328/integrated Del: useless -- https://master.php.net/note/delete/106328/useless Del: bad code -- https://master.php.net/note/delete/106328/bad+code Del: spam -- https://master.php.net/note/delete/106328/spam Del: non-english -- https://master.php.net/note/delete/106328/non-english Del: in docs -- https://master.php.net/note/delete/106328/in+docs Del: other reasons-- https://master.php.net/note/delete/106328 Reject -- https://master.php.net/note/reject/106328 Search -- https://master.php.net/manage/user-notes.php
