I can understand how it works now, and where you'd use it...

And I still don't care for it...

I mean, 'else' just doesn't go with 'while', to me...

And you rarely need something as convoluted as the other example.

while ($line = mysql_fetch_array(...)){
  echo $line; //not really right, btw... :-)
}
if (!mysql_num_rows(...)){
  echo "no records";
}

So, really, it just makes confusing PHP code, that doesn't seem to
save much, in most real-world cases I can think of.
