HomeBackend DevelopmentPHP Tutorial用method_exists一直提示方法不存在,请问具体怎么调试这个错误?

$jms=new $control($conf['db']['dsn'], $conf['db']['user'], $conf['db']['password']);
$jms->debugLevel=$conf['debug']['level'];
if(!method_exists($jms, $action)) notfound('方法不存在');


回复讨论(解决方案)

还有人在吗?

print_r(get_class_methods($jms));
看看$action 的值是否在其中

php 说不存在,那就是不存在了

你看下你调用的方法是不是没有引入到项目中导致了明明有这个方法却不能调用的情况。

谢谢楼上两位!

问题昨天晚上自己已经解决。是因为项目用的PDO这个组件,自己是新手,后在php.ini文件里面打开PDO组件支持就可以了。

 $jms=new $control($conf['db']['dsn'], $conf['db']['user'], $conf['db']['password']);
是不是你实例化类方法,里面报的错吧,后面没有执行下去。

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

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.
