New Comment:
I'd love something like this: if there is at least one iteration, even with
break or continue, don't do "else", otherwise, enter the else.
Another great would be even better, something like
"while(..){..}done{...}else{...}"
It could be a new keyword like "whileif".
Anyway, even the first proposed structure would be awesome.

We shouldn't use "if" or "else" for this. We should use new keywords for this.
It seems simple to implement, but maybe they don't want this because of
performance concerns ?
[2013-02-04 09:28:05] kjarli at gmail dot com
I don't really see a problem why not to implement this
[2012-08-23 17:09:14] bensor987 at neuf dot fr
I would like to go further in that way : "iterated". "iterated" would be parsed
if there has been at least 1 iteration in the loop.
id . ' - ' . $array_raw[$i]->label;
}
if ( $cnt_raw > 0 ){
echo some_function( $arr_output );
} else {
echo 'Nothing to display';
}
...
?>
id . ' - ' . $array_raw[$i]->label;
} iterated {
echo some_function( $arr_output );
} none {
echo 'Nothing to display';
}
...
?>

I understand your opinion. You want to make the "else" keyword usable only when
"false" is encountered, like in "if...else". I didn't think about this.
In that case, let's use another keyword, because this syntax is an excellent
idea.
Why not this ?
[2012-08-22 17:05:05] ras...@php.net
It's not that simple. Loops are repeatedly evaluated conditions. It isn't clear
whether adding an else clause would only apply to the first evaluation or also
subsequent ones.

"no such syntax in other languages"what do you mean ? PHP doesn't have the
right innovate ?
I see plenty of cases I would use this syntax. The "else"s would be triggered
if there hasn't been any iteration in the loop. It means : less variables to
use (so less memory usage), less code lines, etc...
There are only advantages to this syntax (and it's pretty simple to understand,
no KISS violation here). It's not because it isn't done by other languages that
we shouldn't implement it.

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!

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.
[2011-02-18 01:14:34] ijrbiz at gmail dot com
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
}
[2010-12-19 13:08:30] trefighter2334 at aol dot com
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.

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.

Yes, you're right, my code was wrong. Next try:
$found = false;
while ($row = mysql_fetch_assoc($result)) {
$found = true;
print 'Here is a result';
...
}
if (!$found) {
print 'No results found';
}
The proposed while/else syntax is indeed a bit more elegant.

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.

Read again. Your code would always print 'No results found' while the intended
change wouldn't.

Can you give a better example to support your request? Your example can
easily be written as:
while ($row = mysql_fetch_assoc($result)) {
print 'Here is a result';
...
}
if (!row) {
print 'No results found';
}
I don't think that this one test is so expensive that it makes it worth
the trouble (and cost) to clutter up the language.

Description:
How about a while...else structure. Often we do
if (!mysql_num_rows($result)) {
print 'No results found';
}
while ($row = mysql_fetch_assoc($result)) {
print 'Here is a result';
...
}
Wouldn't it be nicer to do a
while ($row = mysql_fetch_assoc($result)) {
print 'Here is a result';
...
} else {
print 'No results found';
}
