Problem with each()

I recall reading this somewhere in the past, but can't find the answer after looking for a couple of hours. I am getting this warning: Warning: Variable passed to each() is not an array or object in myfile.inc on line 1 Here's what I'm doing: While doing: $each_array = each($HTTP_POST_VARS) print("key: $each_array[0] value: $each_array[1]"); When I get to an array within HTTP_POST_VARS, it prints: key: var_name value: Array ok, but when I try to do an each on that array: (and maybe this is where I am wrong) $each_array2 = each($each_array[0]) I get the error that what I'm passing to the each is not an array. Can someone help me or point me to the right place? Thanks, David Minor
