note 55716 added to function.end

Here's something useful with arrays that I did: change an items position up or down in array. Thanks to previous posters for some useful functions (included): // $mode -1 (negat) moves the item down, +1 (pos) moves the item up // I used this because i parsed the mode from the query string // You get the picture though // $from_id points which item to move function change_pos($array, $from_id, $mode){ // get hold of the beginning and the end $start = first($array); $end = last($array); reset($array); // find the position in an array array_set_current($array, $from_id); // remember the old value $temp = $archive[ $from_id ]; // move down if ($uusi_id < 0){ if (key($array) != $end) { $array[ $from_id ] = next($array); $array[key($aray)] = $temp; } else echo "Couldnt move it!"; } // move up else if ( key($array) != $start ) { $array[ $from_id ] = prev($array); $array[key($array)] = $temp; save($array); } else echo "Couldnt do it !"; } function array_set_current(&$array, $key){ reset($array); while(current($array)){ if(key($array) == $key){ break; } next($array); } } function first(&$array) { if (!is_array($array)) return null; if (!count($array)) return null; reset($array); return key($array); } function last(&$array) { if (!is_array($array)) return null; if (!count($array)) return null; end($array); return key($array); } ---- Manual Page -- http://www.php.net/manual/en/function.end.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55716 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55716&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55716&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55716&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55716&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55716&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55716&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55716&report=yes Search -- http://master.php.net/manage/user-notes.php
