How long and complicated can a while condition be?

I want to:

define a string variable ($i) starting at "01"
use this in a mysql query
increment the string
dropout of the while when a zero result comes back from mysql

So, would something like:

while ($sql="some multi-lined mysql query containing $i twice" &&
$result=mysql($conn, $sql)){

do some stuff including incrementing $i;

}

presumably the first condition will always return true, will the second
return false if no matches are found? Can a while condition run over
several lines like this? The manual doesn't seem to say.
