有谁知道这个PHP错误消息背后的含义? [英] Does anyone know the meaning behind this php error message?

问题描述

解析错误:语法错误，意外的T_ENCAPSED_AND_WHITESPACE，预计消息为T_STRING或T_VARIABLE或T_NUM_STRING.它来自以下代码行:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING is the message. It came up from this line of code:

$query = ("SELECT * 
             FROM users 
            WHERE user_name = $_POST['user_name'] 
                & password = $_POST['password'] 
                & user_type = $_POST['user_type']");

外面有人知道这一切的意思吗?如果是这样，有人知道如何处理吗?

Does anyone out there know the meaning of all this? If so, does anyone know how to deal with this?

推荐答案

使用:

$query = sprintf("SELECT u.* 
                    FROM USERS u
                   WHERE u.user_name = '%s' 
                     AND u.password = '%s' 
                     AND u.user_type = '%s' ",
                   mysql_real_escape_string($_POST['user_name']),
                   mysql_real_escape_string($_POST['password']),
                   mysql_real_escape_string($_POST['user_type']) );

$result = mysql_query($query);
