Front-end:

Back-end:
/** * 图片上传 * @return [type] [description] */ public function upload() { $file = Input::file('Filedata'); // 不同环境可能获取方式有点不同,可以下打印观察一下 dd(Input()); if($file->isValid()) { // 上传目录。 public目录下 uploads/thumb 文件夹 $dir = 'uploads/thumb/'; // 文件名。格式:时间戳 + 6位随机数 + 后缀名 $filename = time() . mt_rand(100000, 999999) . '.' . $file ->getClientOriginalExtension(); $file->move($dir, $filename); $path = $dir . $filename; return url($path); } } // $realPath = $file->getRealPath(); // 缓存在 tmp 文件夹的文件绝对路径 // $tmpName = $file->getFileName(); // 缓存在 tmp 文件夹的文件名 // $clientName = $file->getClientOriginalName(); // 获取原文件名称 // $extension = $file->getClientOriginalExtension(); // 上传文件的后缀

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
