What this is saying is that $test2 is not an array.
Also, $var1[1] will not work unless $test is a two dimensional array.
The same is true for $var2[1] and $test2.
There isn't anything special about nesting foreach() loops. Something like:
foreach ($array1 as $element1) {
foreach $array2 as $element2)
works just fine. It's just important to remember that array2 will be
processed in its entirety for each element of array1.
