The behavior Sasha describes becomes problematic if your mysql_fetch_array() is followed by extract() in a loop that writes out results from a query. If a field value is null, then extract() won't recreate the corresponding variable, and the variable will remain set to the value from the previous row. This gave some unexpected results until I figured out what was going on. I'll post a workaround here if I can figure out a good one.
