note 27551 added to language.types.array

<?php /* Here is an array difficultly to watch for. The numeric indices into an array are NOT sequential, they are associative keys. */ // define an array with an offset of one $AnArray = array (1 => "Dog", "Cat", "Bat"); // add an element to the 0 index $AnArray[0] = "Rat"; // print this print_r($AnArray); // get this output /* Array ( [1] => Dog [2] => Cat [3] => Bat [0] => Rat ) */ /* The new value was added at the end, not the beginning as intended. Try using the push/pop/shift/unshift functions if order is important in the array. */ // This would have the proper effect from the example. // array_unshift($AnArray,"Rat"); /* The index will not unshift to less then 0 so additional unshift calls will begin to change the indices of the remaining elements. /* Or use the ksort() function to sort the keys. */ ?> -- http://www.php.net/manual/en/language.types.array.php http://master.php.net/manage/user-notes.php?action=edit+27551 http://master.php.net/manage/user-notes.php?action=delete+27551 http://master.php.net/manage/user-notes.php?action=reject+27551
