 * �修�了一次。少了一个query
    $num_rows = 0; while ( $row = @mysql_fetch_object(
   $this->result) ) { $this->last_result[$num_rows] = $row; $num_rows++; } while(
   $i < @mysql_num_fields($this->result)) { $this->col_info[$i] = @mysql_fetch_assoc(

 * This is a bug in php’s mysql interface (see [http://bugs.php.net/bug.php?id=31288](http://bugs.php.net/bug.php?id=31288)).
   I just tracked it down and reported it to Zend. If you build your own PHP from
   source, the workaround is to comment out line 2250 of ext/mysql/php_mysql.c (
   in version 5.0.3) and rebuild (it crashes because this line ‘s referencing a 
   pointer that hasn’t been set).

 * Changed it in my situation to your php/mysql code but didn’t work, using php 
   5.03 too here…
