一个很普通查询输出函数现在表中有10条数据调用的时候因为要把结果转成XML所以不能在函数体里做echo但是这样调用只能输出最后一条记录,求能在调用页面输出整表内容的方法调用echo main_shopactive();函数体function main_shopactive(){ //商场活动查询,返回逆向排序的最后一条活动记录 $conn = mysql_connect_conn(); $sql = "SELECT * FROM wx_active order by id desc limit 0,30"; $rs = mysql_db($sql,$conn) or die('查询记录失败!'); if(mysql_num_rows($rs) > 0) { while($row = mysql_fetch_assoc($rs)) { $my_active = $row['concent']; } } else { $my_active = 'NO ACTIVE'; } return $my_active;}
回复讨论(解决方案)
while($row = mysql_fetch_assoc($rs))
{
$my_active[] = $row['concent'];
}
楼上正解,。。
返回值是数组,调用呢?
调用怎么一次性读出所有表内值?
foreach(main_shopactive() as $v) echo $v.'
';
你可以
$my_active .= $row['concent'];
return $my_active;
也可以
$my_active[] = $row['concent'];
return join('', $my_active);
版主大人你的第一种方法和我原代码有什么区别呢?
区别在于多了一个点
不要小看这一点,有了它就有了质的变化
版主老大很奇怪的现象啊。dior 资生堂 这是两个品名后面应该分别有楼层地点分类,现在全都连接到一起了
结果应该是这样的:'?dior一楼化妆品0412-8999960资生堂一楼化妆品0412-89999961'
现在却是这样:'dior资生堂一楼一楼0412-89999600412-89999961化妆品化妆品'
什么原因啊?字段排列顺序完全不对呢。
调用页面
$floor_find = new floor_product_lookfor();echo ($floor_find->floor_product('一楼'));
原来类和函数class floor_product_lookfor{ function floor_product($floor_nunmer) { $conn = mysql_connect_conn(); $sql = "SELECT * FROM wx_floor where goods_floor ='$floor_nunmer' order by goods_id desc"; $rs = mysql_db($sql,$conn) or die('查询记录失败!'); if(mysql_num_rows($rs) > 0) { while($row = mysql_fetch_assoc($rs)) { $floor .= $row['goods_name']; $name .= $row['goods_floor']; $tel .= $row['goods_tel']; $type .= $row['goods_type']; } } else { $floor = 'NO GOODS INFORMATION'; } return ($floor.$name.$tel.$type); } }
是不是因为有2个以上的字段就不能用 . 连接
没有什么可奇怪的
既然你简化了你的代码(没有给出记录间的分隔符)那当然是混在一起的
至少你需要给出你期望的数据格式
其实产生 xml 节点数据是可以在 sql 指令中直接完成的
其实也不算是简化了,只是我以为这个方法可以通用就套进其他的函数里了。因为是微信只能用他固定的接口和代码了~
这样的效果就是我所期望的,麻烦版主大人了

while($row = mysql_fetch_assoc($rs))
{
$value .= $row['goods_name'] . $row['goods_floor'] . $row['goods_tel'] . $type .= $row['goods_type'];
}
return $value;
谢谢!

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
