php php framework php error handling thinkphp

http://us.php.net/manual/zh/function.set-error-handler.php

以下级别的错误不能由用户定义的函数来处理: E_ERROR、 E_PARSE、 E_CORE_ERROR、 E_CORE_WARNING、 E_COMPILE_ERROR、 E_COMPILE_WARNING,和在 调用 set_error_handler() 函数所在文件中产生的大多数 E_STRICT。

<code>   /**
     * 自定义错误处理
     * access public
     * @param int $errno 错误类型
     * @param string $errstr 错误信息
     * @param string $errfile 错误文件
     * @param int $errline 错误行数
     * return void
     */
    static public function appError($errno, $errstr, $errfile, $errline) {
      switch ($errno) {
          case E_ERROR:
          case E_PARSE:
          case E_CORE_ERROR:
          case E_COMPILE_ERROR:
          case E_USER_ERROR:
            ob_end_clean();
            $errorStr = "$errstr ".$errfile." 第 $errline 行.";
            if(C('LOG_RECORD')) Log::write("[$errno] ".$errorStr,Log::ERR);
            self::halt($errorStr);
            break;
          default:
            $errorStr = "[$errno] $errstr ".$errfile." 第 $errline 行.";
            self::trace($errorStr,'','NOTIC');
            break;
      }
    }

但是thinkPHP 的自定义错误方法却想处理这些错误,这怎么可能呢,所以这样设计就没有意义了是吧。

明知道没用,我不知道这样设计意义何在,求解释!

还有这个问题:http://segmentfault.com/q/1010000002703753/a-1020000002703757 我理解是对的吧。

谢邀,我不是ThinkPHP用户,只能猜测一下。

这样设计的意义在于框架中使用trigger_error()触发一个用户级别的错误后,使用用户定义的函数产生对开发者友好的输出。

至于为什么会判断E_ERROR、 E_PARSE、 E_CORE_ERROR、E_COMPILE_ERROR我猜可能是作者想多了。

这个设计应该没有问题,很多框架都是自己管理捕获错误。优势是开发和线上你可以自己控制错误的显示信息,其次通过日志便于定位错误。

以下级别的错误不能由用户定义的函数来处理: E_ERROR、 E_PARSE、 E_CORE_ERROR、 E_CORE_WARNING、 E_COMPILE_ERROR、 E_COMPILE_WARNING,和在 调用 set_error_handler() 函数所在文件中产生的大多数 E_STRICT。

测试了一下,ob_start()系列函数不能控制以上级别的错误输出,并且以上级别的错误也不能由用户来触发,即不能使用trigger_error触发。

实在不好意思,我不是 ThinkPHP 用户,也不喜欢这个东西,所以,没法儿帮到你哈

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Explain the match expression (PHP 8 ) and how it differs from switch. Explain the match expression (PHP 8 ) and how it differs from switch. Apr 06, 2025 am 12:03 AM

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
