A summary of how to recursively delete a specified folder in PHP,

The example in this article summarizes two methods of recursively deleting a specified folder in PHP. Share it with everyone for your reference. The details are as follows:

Method 1:

function recursiveDelete($dir)
{ 
  if ($handle = @opendir($dir))
  {
  while (($file = readdir($handle)) !== false)
  {
   if (($file == ".") || ($file == ".."))
   {
    continue;
   }
   if (is_dir($dir . '/' . $file))
   {
    // call self for this directory
    recursiveDelete($dir . '/' . $file);
   }
   else
   {
    unlink($dir . '/' . $file); // remove this file
   }
  }
  @closedir($handle);
  rmdir ($dir);
  }
}

Method 2:

/*
 自定义的删除函数,可以删除文件和递归删除文件夹
*/
 function my_del($path)
{
 if(is_dir($path))
 {
   $file_list= scandir($path);
   foreach ($file_list as $file)
   {
    if( $file!='.' && $file!='..')
    {
     my_del($path.'/'.$file);
    }
   }
   @rmdir($path);
   //这种方法不用判断文件夹是否为空,
   //因为不管开始时文件夹是否为空,到达这里的时候,都是空的  
 }
 else
 {
  @unlink($path);
  //这两个地方最好还是要用@屏蔽一下warning错误,看着闹心
 }
}
$path='d:/技术文档 - 副本';
//要删除的文件夹
//如果php文件不是ANSI,而是UTF-8模式,
//而且要删除的文件夹中包含汉字字符的话,调用函数前需要转码
//$path=iconv( 'utf-8', 'gb2312',$path );
my_del($path);
