Description:
------------
It would be totally kickin' if we could have 'ELSE' on a loop control.
for example, my current code:
-----------------------
$results = mysql_query($sql);
if(!$results || mysql_errno())
die("gaaah!");
if(mysql_num_rows()<1)
echo "<tr><td>No results found</td></tr>";
else {
while($row = mysql_fetch_assoc($result)) {
//echo rows of a table or something...
}
}
----------------------
could be:
----------------------
$results = mysql_query($sql);
if(!$results || mysql_errno())
die("gaaah!");
while($row = mysql_fetch_assoc($result)) {
//echo rows of a table or something...
} ELSE {
echo "<tr><td>No results found</td></tr>";
}
----------------------
The definition of an else on a loop would be "If the initial loop
condition fails in such a way that the loop never iterates (once or
more), then the ELSE block will be executed instead. Loops supported
would be while, for, and foreach
This would be great for debugging as well, when you're trying to figure
out why things never executed, if there was an 'ELSE { echo " -DEGUB:
never entered lool"; } on loops that must be entered it would tip
programmer's off right away.
just think about it:
foreach($items as $item) {
echo "Item: $item\r\n";
} else {
echo "No items found.\r\n";
}
