将记录拆分为两列

Question

I have a "student" table, having around 5,000 records, in my DB. I want to display those records in two divs. How do I do that without executing the query twice; only using a single query?

Answer 1

Just find where the "middle" is and output the end tag of the div tag and the start tag of the second div:

<? 
$rowcount = mysql_num_rows($recordset);
echo "<div id='div1'>";
$i = 0;
while ($d = mysql_fetch_object($recordset)) {
  echo $d->somefield;
  $i++;

  if ($i == floor($rowcount / 2)) {
      //we have reached the mid-point, let's close the first DIV
      echo "</div><div id='div2'>";
  }
}
echo "</div>";
?>
