php脚本解析nginx日志
nginx日志格式
access_log日志格式
log_format main '$server_name$remote_addr$remote_user[$time_local]"$request"' '$status$body_bytes_sent"$http_referer"' '"$http_user_agent""$http_x_forwarded_for"';
日志参数
server_name : 虚拟主机的主机名称remote_addr : 远程客户端的ip地址remote_user : 远程客户端用户名称time_local : 访问的时间与时区status : 记录请求返回的http状态码body_bytes_sent : 发送给客户端的文件主体内容的大小http_referer : 从哪个页面链接访问过来 http_user_agent : 客户端浏览器信息http_x_forwarded_for : 客户端的真实ip
日志分割符
使用特殊的不可打印字符^A(ctrl+v,ctrl+a)作为日志分割符
根据关键字过滤文件内容
需求
根据http的请求里是否有“weibo”这个关键字提取文件的内容
php代码
/** * Description:按行读取文件内容进行过滤匹配 * * @return array */ function readFileContent ($filename) { $weibo_content = array(); $fh = @fopen($filename, 'r'); if ($fh) { while (! feof($fh)) { $row = fgets($fh, 4096); $row_arr = explode("", $row); if (isset($row_arr[3]) && preg_match('/weibo/', $row_arr[3])) { $weibo_content[] = $row_arr; } } } fclose($fh); return $weibo_content; }

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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
