和mysql_fetch_array()结下的不解之缘.....
Warning: mysql_fetch_array() expects parameter 2 to be long, resource given in www/view.php on line 106

能取出数据,就是报警告而已

确认数据库的连接正常

line 106 就是 $result4=mysql_fetch_array($commentquery,$mylink);

然后我把$mylink去掉了之后..就不报警告了...弄了一个下午也没找出个答案来..求解释

贴出部分代码

PHP code

------解决方案--------------------
第二个参数是决定返回数组的类型,可能的值有: MYSQL_ASSOC, MYSQL_NUM, and MYSQL_BOTH.
显然你的 $mylink 是个连接句柄变量,当然不对了。
