Re: [PHP] Numerical refs to assoc array suddenly "undefined offset"?? From: Brian Tanner (btanner <email protected>)

No.. if you are referencing $my_arr['foo'] ==> then $my_array[0] will not be
set. I think it used to work that way, but it stopped. If you want to
print it out... use $my_array['foo']

If you don't need the associative referencing, you can just use $my_array[],
which will set $my_array[0]

If you want to print out your array elements in order, use:

while (list ($key, $val) = each ($my_array)) {
    echo "$key => $val<br>";
}
