I have a script that crashed a production web server yesterday.
$siteslisted=0;
This loop spun forever.

while ((($index, $name, $address, $zip)=$sth->fetchrow_array) && $siteslisted<$sitesperpage){
# other stuff
$siteslisted++;
}
This one works. while (($index, $name, $address, $zip)=$sth->fetchrow_array){
# other stuff
$siteslisted++;
if ($siteslisted<$sitesperpage) {last;}
}
Can some monk explain to me what I did wrong?
I'm betting it's a stupid mistake like operator precedence,
but I would rather ask and be enlightened before taking
down a production machine.
