php删除非空目录程序代码

php code delete delete principle us document yes Table of contents program non empty

非空目录就是指目录中还有其它文件或文件夹了,删除原理是:先我们进入目录中找出是否是空目录或文件进行删除,如果不是再进入下级目录直到为空目录然后,然后再返回删除上级,也就是遍历目录进行删除了。

算是一篇超简单的php教程了,也入是入门级的东西了,就不多讲了

代码

 代码如下 复制代码

// 说明: 删除非空目录的解决方案
function removeDir($dirName)
{
    if(! is_dir($dirName))
    {
        return false;
    }
    $handle = @opendir($dirName);
    while(($file = @readdir($handle)) !== false)
    {
        if($file != '.' && $file != '..')
        {
            $dir = $dirName . '/' . $file;
            is_dir($dir) ? removeDir($dir) : @unlink($dir);
        }
    }
    closedir($handle);
     
    return rmdir($dirName) ;
}
?>

还有很多的方法,这里就不介绍了,其实程序中的 unlink 删除文件,而rmdir删除此目录。
