Stupid Array Question

[GiffordS]

Ok, so I haven't been working in PHP for awhile and I'm now a bit rusty. Here's the deal:

I have a variable that is also part of an array. I need to remove the variable from the array without unsetting the variable.

Anyone?

That question does not make any sense to me.

Ok, let's say I have a an array, and that array contains three elements, "bob", "joe", and "ed". Now, let's say I want to remove the element "bob" so that my array only contains "joe" and "ed". I know this is a really simple question, but as I said I haven't worked in PHP in quite awhile and I'm just a bit rusty. I've looked through the manual and found all kinds of functions to sort etc, but I cannot remember how to just drop an element from an array.

How 'bout:

If the array looks something like:

$foo = array (0 => 'bob', 1 => 'joe', 2 => 'ed');

Then to remove the element containing 'joe', perform: unset ($foo[1]);

(

http://us2.php.net/manual/en/function.unset.php)

If you need to find the element that contains "joe", use array_search() (

http://us2.php.net/manual/en/function.array-search.php)

but read the page on array_search() and pay careful attention to the warning on that page.

Ok, this is the other half of the question. I also have a variable, independent of the array, $g="bob". I was just afraid that by unsetting the "bob" element from the array that I would also unset the $g variable. As I write this I realize that to unset the $g variable I would actually need to unset($g). Stupid question. I hate not remembering stuff like that. Thanks for the response.
