[SOLVED] Global confusion

[scottybwoy]

I use global quite a bit and thought I understood it.  However When I call it in a function it seems to delete the contents let me show you how I'm utilising it:

<?php
function salesPrep($data_array) {
global $data_array;

echo '<u><b>$data_array</b></u><br>';
print_r($data_array);
?>

 

I thought that would make it available to the code it returns too however it completely wipes the array.  If I remove it, it works fine, but is not accessible to the rest of my code which I want, any pointers?  Thanks.

If you're passing $data_array, you don't also use global $data_array. Pick one or the other...
