How to loop this?

Recommended Posts

The code below is returning the results that I expect. It is inefficient though and I wonder if I can loop my way through this. I've had a couple of attempts but I'm not quite sure whether looping it will work. Is it possible to shorten this code with a loop do you think?

Thanks

[code]

    if ($used4 !== '')
    {
      if ($row3[test_sent_1] == '0')
      {
      $query="UPDATE kanji.$username SET test_attempts=$row3[test_attempts] +'1', test_sent_1='$used4'";
      mysql_query($query);
      }
      elseif ($row3[test_sent_2] == '0')

Try the following:
[code]<?php
if($used4 != '')
  for ($i=1;$i<21;$i++) {
      if ($row3['test_sent_' . $i] == '0') {
          $tmp = $row3['test_attempts'] + 1;
          $q = "UPDATE kanji.$username SET test_attempts=$tmp, test_sent_" . $i . "='$used4'";
          $rs = mysql_query($q) or die("Problem with the query: $q<br>" . mysql_error());
      }
    }
?>[/code]
