ADDITION:
Why I would like to have this is because of the following situation:
----
$test = (float)0; // This would be the return of a function.
// Failhandling
if(!$test)
{
doFailhandling();
}else ...
----
This method has room for misinterpretations.
Ofc, you could test for "$test === false", but I think a general
onFail-handler would be way nicer.
Thanks for reading

To be honest, I'd like to have a general "onFail{}" handler to put
after every function, not only foreach.
Like:
----
foreach($arr as $var)
{
doCode();
}
onFail
{
failHandling();
}
----
or
----
file("file.txt")
onFail
{
failHandling();
}
----
Inside of the onFail-brackets a constant __ERROR__ would be available,
with further information on the error.
Basically, that onFail-handler would be executed upon receiving the
constant FAIL from the function before the onFail-command.
Regards

I agree, this would be a nice addition to PHP6.

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)
