webman快速入门1

1 数据库操作 安装直接看文档  我比较喜欢原生的写法   这里没用连接池 因为他用单利模式 也反复用 性能不比用了连接池差

   //返回值:方法总会返回结果的数组数据。数组中的每个结果都是一个 PHP StdClass 对象，这使你能够访问到结果的      
 $results = DB::select('select * from aa limit 1');
        foreach ($results as $key => $value) {
                　echo $value->name;
        }
        DB::transaction(function () {
         // 返回影响的行数
        $affected = DB::update('update aa set name = 200 where id = ?', [11]);
        $affected =DB::insert('insert into aa (name, email) values (?, ?)', ['11', '11']);
        $affected = DB::delete('delete from aa where id=4');
      $affected =DB::statement('drop table aa');
        print_r($affected);
              });

 2 redis操作

 

$key = 'test_key';
Redis::set($key, rand());

3 常用function函数

<?php
/**
 * Here is your custom functions.
 */
function gff(){
    return 11;
}

4 写入日志

  Log::info('log test');  

 5 中间件
