php递归删除目录的例子

<?php
function deletedir($dir){
      if(!handle=@opendir($dir)){     //检测要打开目录是否存在
               die("没有该目录");
      }
     while(false !==($file=readdir($handle))){
               if($file!=="."&&$file!==".."){       //排除当前目录与父级目录
                            $file=$dir .DIRECTORY_SEPARATOR. $file;
                            if(is_dir($file)){
                                  deletedir($file);
                            }else{
                                  if(@unlink($file)){
                                         echo "文件<b>$file</b>删除成功。<br>";
                                  }else{
                                          echo  "文件<b>$file</b>删除失败!<br>";
                                 }
                }
     }
    if(@rmdir($dir)){
           echo "目录<b>$dir</b>删除成功了。<br>n";
    }else{
           echo "目录<b>$dir</b>删除失败！<br>n";
  }
}

$dir="/var/www/test";
