你能试试吗:
var_dump($result); //should tell you if the result contains anything (and if so, what)
此外:
如果从num行中得到0,则SQL很可能出错。
如果您得到一个数字,但只有打印不起作用,请检查$fullname中是否确实有值
我建议您重新编写代码,以便在准备好的语句中使用Mysqli。$email
没有在任何地方定义?$userid
的值是什么。该id是否有行?@Shamil$fullname定义了如果您回显查询,为什么不显示fullname。你得到了什么?如果查询没有获取记录,而循环将不会运行,因此$fullname和$email将不会被填充为循环外建议….不要再使用mysql\uu
…它不安全,请选择mysqli\u
或PDO
。。。
echo mysql_num_rows($result); // should tell you the number of rows
