why are assignments in conditions bad?

Question

I am using NetBeans for PHP 6.5.

In my code I frequently use the following type of command:

if (($row = $db->get_row($sql))) {
        return $row         


        

Answer 1

how would a code look like if you do not assign the $row value in the loop condition this would be much more complicated i think... although not that good to read for some maintainers, no? well you can do it like

$next = mysql_fetch_assoc($result)
do{
...
...
...

$next = mysql_fetch_assoc($result) or break;
}while ($next)
