确定Laravel 5中是否存在文件 [英] Determining If a File Exists in Laravel 5

问题描述

目标:如果文件存在，则加载文件，否则加载default.png.

Goal : If the file exist, load the file, else load the default.png.

我已经尝试

  @if(file_exists(public_path().'/images/photos/account/{{Auth::user()->account_id}}.png'))
    <img src="/images/photos/account/{{Auth::user()->account_id}}.png" alt="">
  @else
    <img src="/images/photos/account/default.png" alt="">
  @endif

---

结果

它一直加载我的默认图片，而我100％确信1002.png存在.

It kept load my default image while I'm 100% sure that 1002.png is exist.

如何正确检查该文件是否存在?

How do I properly check if that file is exist ?
