Arrays: How to remove entry from array?

[Anon]

I've used PHP very intensively, but I can't get this small thing:

Say i have an array...
<?
$arr = array('a','b','c');
?>
How do I delete 'b' from the array?
There's no built in function for it, at least I can't find it in the documentation.

There is a way to delete the first or the last entry. So a way to move a value to the end would also work.

Anyone have a good solution for this?

unset($arr);

Does this not work?

Let me know as I'm curious as well.

nope that won't work, but the idea is good.

Try this:

unset($arr[1]);

that will remove the 2nd element (arrays start at zero) from the array.
Note: this does not re-order the indexes, so the remaining elements are still at index zero and two!

Or in otherwords, it's becuase the array $arr was not associative? And if so, unset() will not 'unset' elements in associative arrays?
