Answer Posted / Gaurav Singhal

The code <code><?php print contents: $arr[1]; ?></code> works because $arr[1] accesses a single element of the one-dimensional array. However, the code <code><?php print contents: $arr[1][2]; ?></code> does not work since it attempts to access the third element ($arr[1][2]) of a two-dimensional array without initially defining the first and second dimensions.
