[] ThinkPHP 集成FIREPHP 呵呵
tp的调试真的很傻很难用,要想输出trace信息,条件如下:1. app_debug 以及show_page_trace设置成true,2. action 必须有视图 才行在这里发挥了自己的想象终于把 firephp 集成进来了,哈哈哈,方法如下:[就是替换 thinkphp/lib/think/core/log.class.php] 类把 firephp.class.php 复制到 thinkphp/lib/think/core 目录中,修改如下方法:[建议将原有文件备份哦,此仅作测试使用]static function record($message,$level=self::err,$record=false) { if($record || in_array($level,c('log_record_level'))) { $now = date(self::$format); self::$log[] = "{$now} {$level}: {$message}\r\n"; switch($level){ case self::debug: firephp::getinstance(true)->trace($message, $level); break; case self::info: firephp::getinstance(true)->log($message, $level); break; case self::sql: firephp::getinstance(true)->info($message, $level); break; case self::notice: case self::warn: firephp::getinstance(true)->warn($message, $level); break; default: firephp::getinstance(true)->error($message, $level); break; } } }对于 sql的输出,因为 thinkphp/lib/think/db/db.class.php 里面第128行 对 调试参数写死了,必须将其 与 c('app_debug') 绑定,很费解,此处修改为 加一个自定义的,不与原有的相冲突..代码如下:if(c('app_debug') || c('log_record_sql'))在配置文件里面做如下选项,即可:'log_record'=>true, // 进行日志记录'log_record_sql'=>true, // 进行日志记录'log_record_level' => array('emerg','alert','crit','err','warn','notic','info','debug','sql'), // 允许记录的日志级别日志级别可以自增减 呵呵?

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
