Multi Dimensional Arrays

CE_MasterYoda

I have a PHP script accessing a 2-dimensional matrix from a MySQL DB. From the tutorials, and the errors I'm getting, it looks like I can't put variables in for indexes. I sure hope this is not true. I remember being able to do it in C++. Could someone please help me figure out what I'm doing wrong? Here's a snippet.

$member_name=$player_info_result[$i]['cename'];

What's the error?

You can use variables within an array index. You can also use arrays, objects, functions, expressions etc... within an array index.

Try this as a debug step

print_r($player_info_result);

This will show you the data structure of $player_info_result and may clue you in to whats going on with it.

I get "Resource #10" And I know that is not in the database... What does this error mean?

I've never seen it.

What does the print_r give you?

print_r() prints out the whole content of a varible. format of the variable (string, array, ...) doesn't matter.

Well, I forgot to

mysql_fetch_array($player_info_result);

That's why there was nothing in my array. I was thinking that $player_info_result had the array and the information. I suppose I was wrong.

Oh, and BTW, thanks for your help. That print_r() was pretty helpful. :-)

No Problem.

Yeah, print_r is a wonderfull DEBUG tool for anything, especially objects and arrays. My code is full of commented out print_r calls. I use multidim arrays for most everything.
