以前没有这个问题,php升级到5.4出现这个问题
config.php中代码
<code><?php define('host','localhost'); define('username','root'); define('password','root'); define('database','daan'); ?></code>
connect.php中代码
<code><?php require_once 'config.php'; $mysqli = new mysqli(host,username,password,database); if($mysqli->connect_error) { die('Connect Error:'.$mysqli->connect_error); } $mysqli->set_charset('utf8'); ?></code>
index.php中的代码
<code><?php require_once 'connect.php'; ?></code>
接下来问题来了,如果我在index.php
中单单引入connect.php
,php报错,提示我host username password datebase
这几个常量没有定义
但如果这样
<code><?php require_once 'config.php'; require_once 'connect.php'; ?></code>
就正常了,请问这是怎么回事,如何解决

看下这个应该对你有帮助,在回家的路上没法码字

试试将定义的常量名改成大写的试试吧
new mysqli(host,username,password,database);
new mysqli($host,$username,$password,$database);
懂了吗?

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

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.
