How can I get the size of a row of a two dimensional array?

Can I use sizeof with multi-dimensional arrays?

Thats simple, when you have a multi-dimensional array, each
array-element *is* an array.  So, for a two dimensional array like this:

    $Arr[$i][$j]

then:

    sizeof($Arr[$i])

will tell you how many elements in that particular dimension of the
array.
