Quick array question

Hi. Is there an array function that deletes an array element (that's not at the beginning or the end of the array) and return the resultant array? E.g. this is what I want to do: $a = array(1, 2, 3, 4, 5); $b = array_element_delete_function($a, 2); $b now has 4 elements with the following values: (1, 2, 4, 5) Thanks. David
