Larval分页,文件上传，验证码，加密,request

分页怎么分？
1 查询符合条件的总记录数
2 计算总的页面
3 拼凑分页链接
4（重要）使用Limit语法限制分页的记录数
5 展示分页的页码和分页数据

1laravel中文语言包下载

网站是packagist.org

composer require "overtrue/laravel-lang:~3.0"

然后在vendor/caouecs/laravel-lang下src下找到zh-CN,然后复制到项目里的resources/lang下，设置下config/app.php里的'locale' => 'zh-CN',就可以了。

2验证码的下载和安装

Laravel打印出sql

在AppServiceProvider的boot里放入以下代码即可

 public function boot()
    {
        //打印出sql
        DB::listen(function ($sql) {
                foreach ($sql->bindings as $i => $binding) {
                    if ($binding instanceof \DateTime) {
                        $sql->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
                    } else {
                        if (is_string($binding)) {
                            $sql->bindings[$i] = "'$binding'";
                        }
                    }
                }

                // Insert bindings into query
                $query = str_replace(array('%', '?'), array('%%', '%s'), $sql->sql);

                $query = vsprintf($query, $sql->bindings);

                // Save the query to file
                $logFile = fopen(
                    storage_path('logs' . DIRECTORY_SEPARATOR . date('Y-m-d') . '_query.log'),
                    'a+'
                );
                fwrite($logFile, date('Y-m-d H:i:s') . ': ' . $query . PHP_EOL);
                fclose($logFile);
            }
        );
    }
