My function should, in theory, remove an array element, whether enumerative or associative, and return the removed element.
I wanted to make a crossbreed of array_shift() and java.util.Vector.removeElementAt((int)index) inasmuch as remove an array element.
However, if the array is enumerative, I want to be able to reorder the array so that if you have:
array ('apple', 'banana', 'orange');
And you remove $array[1] you should have:
array (0 => 'apple', 2 => 'orange');
How can I do that? I am not familiar with reordering arrays without looping, and I can't afford to loop because this function is called within several embedded loops as it is!
Thanx
