在funcation.php中加入以下代码：

function timer_start() {
  global $timestart;
  $mtime = explode( ' ', microtime() );
  $timestart = $mtime[1] + $mtime[0];
  return true;
}
timer_start();

function timer_stop( $display = 0, $precision = 3 ) {
  global $timestart, $timeend;
  $mtime = explode( ' ', microtime() );
  $timeend = $mtime[1] + $mtime[0];
  $timetotal = $timeend - $timestart;
  $r = number_format( $timetotal, $precision );
  if ( $display )
    echo $r;
  return $r;
}

然后，模板部分加入：

<?php timer_stop() ?>
