Hey, i was also looking for some while {} else {} feature...
but i think it could be difficult to implement such a function in php.
Because the else{} event would start after the while{}-loop ends -> everytime
after the last result!
think about it!

This is a great idea. I am currently needing something like this, but however
got
around it using flags and making the flag true in the while. It would be alot
more
convenient if there was an else!
Please add this feature!!!

I agree. I think a while () else () will make things easier. I was researching
and
found out that it doesnt exist yet.
while($row = mysqli_fetch_assoc($result)) { }
with al else I would fix it.. I am new in PHP,. I will try to find something to
fix it. but if the while else is release in a new version that would be nice.

Highly agreed, this request would be very practical for improved coding
structure and
follows logical language syntax nicely.
function remove_items (&$arr, $needle) {
while ($key = array_search($needle, $arr)) {
unset( $arr[$key] );
} else return false; // No items present
return true; // Item(s) removed
}

I'd love to see something like Python's while/else logic implemented in PHP.
This logical construct would allow developers to define blocks of code in else
{} that'd run upon a natural exit from the while(){} loop caused by said loop's
condition becoming FALSE; however, the else {} would be skipped over if the
loop
exits unnaturally -- a la through a break statement or because of an exception.
It is to die for on a semi-daily basis for me (in python)... but I'm not sure
this is what the developers above (and their examples) have in mind or not.
Either implementation would prove useful to me.

try {
foreach ($nullValue as $nothing) {
echo 'valid input';
} else {
//suppress notice
echo 'null value';
}
//or/and
} catch (ExceptionObjectNotIterator $e) {
//object doesnt implement Iterator
echo $e->getMessage();
}
