overwrite global variables in loop...

[knelson]

well, I had a feeling that I would be bitten by this one when I tried to reuse the function:

1. I have functions that declare variables to be GLOBAL, e.g.,

function ext_size_display()

{
global $init_ext_size_results;

foreach ($init_ext_size_results as $unique_ext_size_results)				
 {
   echo "$unique_ext_size_results";
 }

}

Each one is a result return from either Oracle or MySQL, and they wouldn't display on my original query page without being declared global.

However, now I need to use these functions in a loop (a report returning multiple records) and I'm getting fatal errors because the variable is already declared.

2. Is there a way to overwrite/erase these global variables at the beginning of the loop, and is this advisable? Go back to the drawing board?

thanks for your time once again. knelson

I don't think you'd get Fatal errors for what you've just described...can you post the code you're using?

diego...very true. that code, on its own, is innocuous.

when I simply paste the code (in non-function form) directly into my db query results page, everything works. It's only when I have my display functions abstracted into include files, and declaring variables to be GLOBAL, and putting the function into a WHILE loop--that I get fatal errors for "variable already declared".

I'm going to try some other things and perhaps repost with a modified question.

thanks for your interest and help..
