[PHP-WIN] How to remove a value from a array

[Steen Rabøl]

Hi

How can I remove a vale from a array()

eg;

$a = array("1","2","3");

if I then unset($a[1]) the value is NULL, or the offset is empty, and you get a error 
if yoy try to access that element.

What I want/need is a function whic can remove a valy/key from a array

Does such a function exists ?

Thanks in advance

Steen
