I have to agree with the OP. foreachelse (or something similar) is
really
needed. I do like the suggestion posted by cerlestes at googlemail dot
com:
foreach($arr as $var)
{
doCode();
}
onFail
{
failHandling();
}
A fail handler would prove useful,however I can see it may have some
limitations, in which case an else option on the foreach would be
satisfactory.
Whilst we're at it, it may as well be added to while statements too.

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
