下面有个方便的解决办法，从官方munual上看到 bdobrica at gmail dot com 留言的： As a solution to the problem pointed in the post reffering to mysql_affected_rows() returning 0 when you are making an update query and the fields are not modified although the query is valid, i'm posting the following function. It is very simple and based on a previous post. 代码如下: function mysql_modified_rows () { $info_str = mysql_info(); $a_rows = mysql_affected_rows(); ereg("Rows matched: ([0-9]*)", $info_str, $r_matched); return ($a_rows < 1)?($r_matched[1]?$r_matched[1]:0):$a_rows; }
