一般情况下PHP作为CGI运行和Apache模块运行，PHP很少在命令行（CLI）下运行。在（CLI）命令行下PHP文件中使用include、require等引入时，使用相对路径一定要先切换当前的工作目录才行，否则就会报错，找不到文件。下面看看PHP命令行（CLI）下执行相对路径问题的完美解决方法。

$cur_dir = dirname(__FILE__); //获取当前文件的目录 chdir($cur_dir); //把当前的目录改变为指定的目录。 require(../class/a.php);//引入相对路径文件

另外一个小细节，在用PHP写入文件换行时，有时使用\r\n不生效，请检查\r\n是否用的单引号，这里必须使用双引号。

这样，我们就可以在访问量小的时候用PHP做一些定时的处理，其实在Linux下和crontab定时任务配合，PHP可以帮我们做很多事。比如当天统计，数据库备份，日志清除和一些日常维护等。
