Global Array in Function???

[Anon]

I thought I had posted this question last Friday, but I did not get any responses and could not find it in the forum.. guess it didn't get posted.

I have an array that I need to make changes to within a function. ( what the function does is copy all valid array data cells into a secondary temp array, unsets the global array and then copies the data back in. ) This strips out all invalid array cells and re-keys the array.

When printing the count inside the function everything works, all empty cells are eliminated. As soon as the function ends, the array has all the empty spaces back in.. just like the function never affected it.

Any Ideas?? I have the array defined as global within the function. Anything else I have to do??

Please help!

You can pass parameters by reference, which means you don't pass a copy if the value, but you pass a reference to the value.
If you change the value of a variable that was passed by reference, you actually change the variable that was passed:

$aArray = array(1,2,3);
changeMyArray($aArray);
print_r($aArray);
exit;

function changeMyArray(&$aMyArray)
{
$aMyArray = array(6,7,8);
};
