就是现在我有一个存放日志的文件夹,需要怎么做才能用程序做到将较早的日志文件进行删除?大神们有方法么?


回复讨论(解决方案)

foreach(glob('日志文件目录/*.*') as $fn) {  if(filemtime($fn) < 指定的时间) unlike($fn);}

可以写个脚本删呢,一天跑一次检查过期(比对当前时间和日志的最后修改时间或者创建时间)的日志文件给予删除

脚本的话比如这样,删除内容修改超过7天的文件

find ./ -mtime +7 | xargs rm -rf 

是要用php完成这个工作呢,就是我有百度看有提供将文件夹里面的文件按照时间进行排序,但是我使用了都是不可以的。。。
这是我的代码
function dir_size($dir,$url){
     $dh = @opendir($dir);             //打开目录,返回一个目录流
     $return = array();
      $i = 0;
          while($file = @readdir($dh)){     //循环读取目录下的文件
             if($file!='.' and $file!='..'){
              $path = $dir.'/'.$file;     //设置目录,用于含有子目录的情况
              if(is_dir($path)){
          }elseif(is_file($path)){
              $filesize[] =  round((filesize($path)/1024),2);//获取文件大小
              $filename[] = $path;//获取文件名称                     
              $filetime[] = date("Y-m-d H:i:s",filemtime($path));//获取文件最近修改日期   
              $return[] =  $url.'/'.$file;
          }
          }
          }  
          @closedir($dh);             //关闭目录流
          array_multisort($filetime,SORT_DESC,SORT_STRING, $files);//按时间排序
          return $return;               //返回文件
     }
dir_size("htdocs","htdocs");

?>
运行后出现问题
 array_multisort(): Argument #1 is expected to be an array or a sort flag
最好的结果是我希望php运行后能将文件按照时间的顺序进行排列,这样我就能用函数有选择性的进行文件的删除。。。

学习了。。。。

array_multisort($filetime,SORT_DESC,SORT_STRING,  $files);//按时间排序
$files 在哪里赋值的?

array_multisort($filetime,SORT_DESC,SORT_STRING,  $files);//按时间排序
$files 在哪里赋值的?

我查了下函数的用法,知道了array_multisort函数的用法,最后一个给的参数应该是一个数组,但是我不知道怎么给第四个参数赋值。$files应该是指文件里面的所有文件,我不知道怎么去使用。。$files=$return[] =  $url.'/'.$file;?

我把$files改成了$return还是没有用。。。

函数可改写为

function dir_size($dir,$url){  $dh = @opendir($dir);             //打开目录,返回一个目录流  $return = array();  $i = 0;  while($file = @readdir($dh)){     //循环读取目录下的文件    if($file!='.' and $file!='..'){      $path = $dir.'/'.$file;     //设置目录,用于含有子目录的情况      if(is_dir($path)){      }elseif(is_file($path)){        $files[] = array(          'filename' => $path,//获取文件名称                               'filesize' => round((filesize($path)/1024),2),//获取文件大小          'filetime' => date("Y-m-d H:i:s",filemtime($path)),//获取文件最近修改日期             'return' => $url.'/'.$file          );        $filetime[] = filemtime($path);//获取文件最近修改日期         }    }  }    @closedir($dh);             //关闭目录流  array_multisort($filetime,SORT_DESC,SORT_STRING, $files);//按时间排序  return $files;               //返回文件}

恩恩,我用了您的代码,发现可以使用的。
然后我发现还有一种方式就是直接把$files放在替换成$return,因为之前的数据都是存在return里面的。
