[PHP] Array question

[Chris]

Hi,
How do I get the index,number of an array if reffering to an array via string?
Ex:
I have 100 arrays, and I want to know what #  myarray["something"] is.
I looked at Current, but how do I move the pointer to where "something" is in the 
array?

Would this work:

$null = myarray["something"];
$indexofsomething = current();

Thanks,
Chris
