[SOLVED] How to extract an array index number?

[DamienRoche]

I have this array - $arr[]

 

Say I do this:

 

foreach($arr as $arrtest){

echo "$arrtest index number:()";

}

 

How would I go about getting the index number of $arr? I can just apply a loop because the arr isn't always in the same order.

 

Any ideas?- thanks.

Use the expanded syntax for foreach

 

 

foreach($arr as $key => $arrtest){

 

echo "$arrtest index number:($key)";

 

}

Perfect! -thanks a lot!

Use the manual, it's the best resource. foreach()

Thanks Orio, I use the manual every day. This seems to be an array thing, the only relation to the foreach is that it has the support for this array technique. I just tested outside a foreach.

 

Thanks for reaffirming the importance any way.
