laravel 查询之大小写敏感
其实和laravel 无关，只需在MySQL执行:

ALTER TABLE '表名' CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

如果是数据迁移:

Schema::create('info', function (Blueprint $table) {
            $table->increments('id');
            
            $table->charset = 'utf8';
            $table->collation = 'utf8_bin';
            
            $table->timestamps();
        });
        \DB::statement("ALTER TABLE `info` comment '详情'");
