本文所述为ThinkPHP调试模式与日志记录的使用方法,该功能在进行ThinkPHP项目开发的过程中起到非常重要的作用,有必要加以理解并掌握。具体方法如下:
1、可以在config.php中进行设置,默认为关闭状态。
开启方法如下:
'APP_DEBUG' => true
打开\ThinkPHP\Common\debug.php文件可以查看debug的默认设置如下:
return array( 'LOG_RECORD'=>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 'DB_FIELDS_CACHE'=> false, //数据库字段缓存 'SHOW_RUN_TIME'=>true, // 运行时间显示 'SHOW_ADV_TIME'=>true, // 显示详细的运行时间 'SHOW_DB_TIMES'=>true, // 显示数据库查询和写入次数 'SHOW_CACHE_TIMES'=>true, // 显示缓存操作次数 'SHOW_USE_MEM'=>true, // 显示内存开销 'SHOW_PAGE_TRACE'=>true, // 显示页面Trace信息 由Trace文件定义和Action操作赋值 'APP_FILE_CASE' => true, // 是否检查文件的大小写 对Windows平台有效 );
注意事项:DB_FIELDS_CACHE数据库字段缓存默认关闭状态,如果开启的话,会在Runtime\Data文件夹下生成文件缓存,并且修改表之后,如新加了字段,这个缓存无法记录你的操作,需要我们手动删除一次,对表的修改才会成功。
将'APP_DEBUG' => true后,访问页面会出现如下图的DEBUG提示:
如果只想显示一部分提示信息,如运行时间,内存开销等,
可以在config.php中进行相应的设置即可,如:
//'APP_DEBUG' => true, // 调试模式开关 'SHOW_RUN_TIME' => true, //运行时间显示 'SHOW_ADV_TIME' => true, //显示详细的运行时间 'SHOW_DB_TIMES' => true, //显示数据库的操作次数 'SHOW_CACHE_TIMES'=>true, //显示缓存操作次数 'SHOW_USE_MEM' => true, //显示内存开销
提示信息如下图:
2、页面Trace信息的自定义:ThinkPHP\Tpl\PageTrace.tpl.php
自定义的方法一:在config.php的同级目录加上一个trace.php文件,代码如下:
<?php return array{ '当前的server信息'=>$_SERVER['REMOTE_ADDR'], }; ?>
自定义的方法二:在Action方法中添加:
$this->trace('调试测试','5211314');
3、输出调试法:
halt('aaaaaaa');//输出aaaaaa并且中断程序执行
4、模型调试:显示SQL语句
$User=new Model('User'); $User->find(1); echo $User->getLastSql();//输出最后执行的一条SQL语句
5、日志记录ThinkPHP\Lib\Think\Core\Log.class.php
config.php中设置
'LOG_RECORD'=>true,//开启了日志记录 'LOG_RECORD_LEVEL'=>array('EMERG','ALERT','ERROR'),
希望本文所述方法对大家有所帮助。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
