Description:
------------
Why PHP does not provide some basic and ready variables for foreach-loops? A variable, for example, for holding the iteration count. Because foreach-loops are an abstract way of looping (than basic for-loop), hence it could be way better to provide at least two (or event one) variables for foreach-loops which updates on every iteration.

Test script:
---------------
For example, the following can save the life of PHP programmers:

foreach($list_of_users as $user) : $i
{
   // the variable of $i updates on every iteration to 
   // reflect the current iteration count
}

Or for more easier programming, a second variable can be added to reflect $is_last status:

foreach($list_of_users as $user) : $i, $is_last
{
   // the variable of $i updates on every iteration to 
   // reflect the current iteration count

   // $is_last is true if the iteration is the last iteration, and is
   // always false for all other previous iterations.
}

// the same case can even be true for $is_first variable
