                <?php }
        }
    }
}
?></code>

<code><?php $page = $_GET['pages'];   //第几页
$page_num = 10;  设置每页显示条数
/*
不知道你的api都有什么参数,我模拟个通用的分页api函数吧;
通常传递两个参数就可以了  一个是起始位置,一个是显示条数
起始位置 = 第几页 * 每页显示条数   显示条数为你的自定义条数
*/
$page_mes = pagination($page * $page_num, $page_num); //pagination分页接口方法
foreach($page_mes as $key => $val){
    //分页数据显示
}
?></code>

大概就是这样的...

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.
