Answer 1

Rather than incrementing it every time the loop runs and wasting useless resource, what you can do is, if the value is 0 for the first time, then print the statement and make the value of the variable as non-zero. Just like a flag. Condition, you are not changing the value of the variable in between the loop somewhere. Something like this:

Show this once
";
        $i=1;
      }

      print "
display everytime
";
   }
?>
