I know hardly anything about website development and found myself needing a while-else statement. Great that we can Google and that I picked this suggested site. Thanks for the previous comments that suggest simple workarounds.

I was just hoping for this functionality about 5 minutes ago. There is obvious workarounds, but this would be much much cleaner.

Woops, wrong move…like i was saying :
A solution (simpler than taaniel’s one) is to put a flag :

$hasresult=false;
while($row=mysql_fetch_assoc($mysqlResult)){
[do whatever you want]
$hasresult=true;
}
if(!$hasresult){
[do whatever you want]
}

There is a feature request to this:
Request #26411 – while {} else {}

There is also a feature request for the corresponding foreach statement:
Request #46240 – Build in foreach else support

how do i do it here?

while(!(connection_aborted() || connection_status() == 1) && $bytes_sent content_length)

{

//this sends data

if(connection_aborted() || connection_status() == 0) {log_write(“Seems the client aborted the file download”); break;}

}

I wholeheartedly agree, here’s something that I’ve considered using that represents the while-else. The only problem is if you change the list=fetch line, you have to do it twice.

if (list($a,$b) = mysql_fetch_row($result)) {
do {
process($a,$b);
} while (list($a,$b) = mysql_fetch_row($result));
} else {
print “No results returned”;
}

I definitely agree. In fact, I was just trying to just that and upon that not working I googled it and realized it doesn’t exist. It’s a common sense statement, if you ask me (hence why I tried doing it). I reckon a post on php.net’s forum would be a good way of seeing why this cannot be done and if it can, give it some thought and perhaps enough traction to be implimented.

[...] while-else statement — A while-else statement would be perfect for MySQL results: loop through the results, or if there were no results display an error. [...]

agreed, but alternative way is use one variable and if after while, for example

$q = mysql_query(‘SELECT * FROM tbl’);
$n = 0;
while($r = mysql_fetch_assoc($q))
{
// do something
++$n
}
if(0 == $n)
{
// no rows found
}

PHP doesn’t support that, but Smarty does.

I normally use
foreach / else to display tables.

Interesting thought, I am inclined to agree with you, however I do not know what would go into making something like this happen, and I have no idea if it is even feasible. Perhaps someone with more knowledge on the subject will chime in.
