Having the 'else' in case of an empty array would be soo nice, please do add
this
option!

foreach(){}else{} is a good id but perhaps need to be improved :
this simple example can't be converted to foreachElse (due to <ul/>) :
-------
if(count($data)>0){
echo "<ul>";
foreach($data as $item){
echo "<ul>$item<ul>";
echo "<ul>";
}
else
{
echo "<p>No think to see :(</p>";
}

I completely disagree about the onFail section.
The foreach else would be useful if there is no item. As a shortcut to
if(count($elements) == 0).

Opposing general consensus, I think adding such feature would be semantically
ambiguous. The foreach function does not fail, it has types it can handle
(assoc
array, object) and that it can't handle (scalar). A function can always return
a
result that may be valid for foreach but not the expected format, so I think
data sanitizing is best done dilligently. This is just a lazy-man's hack for a
non-issue. For the function completion status (onFail), there is already such a
construct: try {throw()} catch(){} which already supersets the imagined onFail
implementation. Only thing I would hindsight: it would have been SOOO nice if
php had a false/null/na result convention, as well as an error/exception
convention and it would actually stick by it. Each module signals completion,
computability, singular cases and errors as it well pleases.
