The content of this article is about how to obtain the first-level directory of files (pure code) in PHP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

php obtains the first-level example code of the file directory (solve the problem of Chinese garbled characters);

// 获取目录一层的方法
/*
   *  @param  readfileone //读取一层文件夹内容
   *  @param  dir  // 查找的路径
   *  @param
   *  @param
   */
function   readfileone($dirName){
    $array=array();
    $dir=&#39;./Public/Uploads/&#39;.$dirName;
    if(is_dir(iconv(&#39;utf-8&#39;,&#39;gb2312&#39;,$dir))==true){
        if($handle=opendir(iconv(&#39;utf-8&#39;,&#39;gb2312&#39;,$dir))){
            while(false!==($files=readdir($handle))){
                $files=iconv(&#39;gb2312&#39;,&#39;utf-8&#39;,$files);
                if($files!="."&&$files!=".."){
                    $files=iconv(&#39;utf-8&#39;,&#39;utf-8&#39;,$files);
                    $dir=iconv(&#39;utf-8&#39;,&#39;utf-8&#39;,$dir);
                    if(is_dir($dir."/".$files))
                    {
                        $new_dir=$dir."/".$files;
                        readfileone($new_dir);
                    }
                    else
                    {
                        $str=$dir."/".$files;
                        $str=iconv(&#39;utf-8&#39;,&#39;utf-8&#39;,$str);
                        // session(&#39;success.file&#39;,$str);
                        array_push($array,$str);
                    }
                }
            }
        }
        closeDir($handle);
    }else{
        //  echo &#39;没有找到目录&#39;;
        array_push($array,&#39;没有找到目录&#39;);
        array_push($array,&#39;fail&#39;);
    }
    return $array;//返回二维数组
