you can do with unset

unset($cars[2]);

But after that you need to iterate array with foreach

If you follow this up by doing `$cars = array_filter($cars)` it will remove the empty array items as well. :) – Merijn Feb 01 '11 at 08:43
What happens if "volvo" is array item 3? – Ben Everard Feb 01 '11 at 08:43

@Merjin What do you mean by "empty array item"? – deceze Feb 01 '11 at 08:44
Whoops. I meant 'empty strings' but I just tried and unset also removes the item from the array. No empty spaces left to trim, so ignore my other comment. – Merijn Feb 01 '11 at 08:50

You can use the following thing to delete the x element from array

array_splice($cars,2,1)

This will delete the 2nd element in array and return the remaining array, if you want more elemetns to be deleted change 1 to number of elements that needs to be deleted.
