PHP对了,可是对接到微信只返回array
$result = mysql_query($sql, $link); // 执行查询语句
$res=array();
while($row = mysql_fetch_array($result)){
if(条件){
$res[] = $row["title"].$row["answer"];
}
}
return $res;
?>
用这个之后PHP是对,可是接到微信就变成单独的回复一个array
回复讨论(解决方案)
把数据连接成串,或编码成 json
return json_encode($res);
return json_encode($res);
这个个也不行啊,回复的是乱码
有人会吗,大师吗
在echo json_encode之前,加上:header('Content-type:application/json;charset=utf-8');

while($row = mysql_fetch_array($result))

return json_encode($res);
mysql_close($link);

会不会是这个有错误?

返回值为空?那么直接return "hello world";是什么结果?

数据库的是这样的
你的表字段是UTF-8,所以应该 mysql_query("set names utf8",$link);
另外,有个地方稍微改下(改不改都行,不过echo的数据都应该是XML格式的):
if(!empty($keyword )){ $msgType = "text"; $contentStr = chaxun($keyword); $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr;}else{ $msgType = "text"; $contentStr = "input something..."; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr;}

都改了,还是不行,烦死了,用return返回array,用echo 回复公众号暂停服务
1、你是在做微信应用,而微信都是 utf-8 编码的
所以你 mysql_query("set names GBK",$link); 是不对的
要 mysql_query("set names utf8",$link);
2、你把传入的 utf-8 数据 $keyword 当做 gbk 解释
这就造成了 chaxun 函数返回空数组
当然确实不存在的时候,也是返回空数组的
3、由
$contentStr= chaxun($keyword);
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
可知,$contentStr 应是一个字符串,而 chaxun 返回的是数组,所以可能需要
$contentStr = json_encode(chaxun($keyword));
或
$contentStr = join(',', chaxun($keyword));
1、用echo 回复公众号暂停服务====》可能是代码有语法错误或者error,在你的域名里运行这个脚本看看有没有报错。
2、试一下,不进行查找数据库,直接让$contentStr = "字符串";然后echo $resultStr; 看看是不是数据取出问题

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
