12年毕业至今，一年c#，2年php，几个月node，因为一些原因再次离职，接到腾讯互娱的php面试电话，匆匆准备了一番，便去了科兴科技园腾讯的高大上办公楼。

1.笔试

试题大部分网上都有，例如：

用最少的代码写一个求3值最大值的函数.（min（）函数）
php中写一个函数，能够遍历一个文件夹下的所有文件和子文件夹.

<span>function</span> my_scandir(<span>$dir</span><span>)  
{  
   </span><span>$files</span> = <span>array</span><span>();  
   </span><span>if</span> ( <span>$handle</span> = <span>opendir</span>(<span>$dir</span><span>) ) { 
      </span><span>while</span> ( (<span>$file</span> = <span>readdir</span>(<span>$handle</span>)) !== <span>false</span><span> ) {  
        </span><span>if</span> ( <span>$file</span> != ".." && <span>$file</span> != "."<span> ) {  
           </span><span>if</span> ( <span>is_dir</span>(<span>$dir</span> . "/" . <span>$file</span><span>) ) {  
             </span><span>$files</span>[<span>$file</span>] = <span>scandir</span>(<span>$dir</span> . "/" . <span>$file</span><span>);  
           }</span><span>else</span><span> {  
             </span><span>$files</span>[] = <span>$file</span><span>;  
          }  
       }  
   }  
   </span><span>closedir</span>(<span>$handle</span><span>);  
   </span><span>return</span><span>$files</span><span>;  
 }  
}

</span><span>$files</span>=my_scandir('E:\wamp\www'<span>);
</span><span>print_r</span>(<span>$files</span>);
