Please add a foreach else. It would save so much programming time and
eliminate so much room for error. It's so simple... foreach (){} else
{}

PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE

Description:
------------
Each time you want to foreach an array, you first have to check with 
a count or empty if you want to give a message or w/e to notify there 
is no entry to an array (or object if implements like iterator).

If possible add a else option to foreach.




Reproduce code:
---------------
<?php // old style
if(count($myArray) > 0) {
    foreach($myArray as $key => $value) {
    }
}

//new style

foreach($myArray as $key => $value) {
} else {
   // empty array/object
}
(kinda like how smarty implements it)
