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.

Any PHP developer there?

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.
