本文实例讲述了PHP使用内置dir类实现目录遍历删除的方法。分享给大家供大家参考。具体实现方法如下:

function clearDir($dir)
{
 if (file_exists($dir))
 {
  if(!is_dir($dir))
   exit("{$dir}不是一个目录");
  else
  {
   $dirObj = dir($dir);
   while ($file = $dirObj->read())
   {
    if (is_dir($dir .'/'. $file) && $file !== '.' && $file !== '..')
    {
     clearDir($dir .'/'. $file);
     if (@!rmdir($dir .'/'. $file)) 
      echo "没有权限删除{$dir}/{$file}目录 <br/>";
    }
    elseif ($file !== '.' && $file !== '..')
    {
     if (unlink($dir .'/'. $file)) 
      echo "{$file}文件成功删除<br />";
    }
   }
  }
 }
 else
  exit("{$dir}不存在");
}
clearDir('./demo');
Copy after login

希望本文所述对大家的php程序设计有所帮助。
