I'm sorry, I missed a really big problem with what you're doing.

When you use foreach(), the value that it gives you (in your case, via the
$value variable) is not a reference to the array item, its a copy of it, so
modifying the copy doesn't modify your original array.

Use this (this should work):

for($i=0; $i < size($numeric_array); $i++) {
        if(strstr($numeric_array[$i],","))
        {
                $numeric_array[$i] =
ereg_replace(",","",$numeric_array[$i]);
                echo "comma stripped";
        }
}

Give that a shot and see what happens...
