关于PHP调去函数问题在线等--
$id =$_GET['id'];
?>
如果是:baidu.php?id=b 那就调取b数据 如果url传输没有?id=b 那就自动默认调取a的数据
请问上面代码该怎么修改啊
------解决方案--------------------
你说 a,b 是函数?
if($id='b'){
echo b() ; //如果 b是字符串变量 就 echo $b;
}else{
echo a();
}
?>
------解决方案--------------------
var $b="";<br /> if(!empty($_GET['id'])){<br /> $b=$_GET['id'];<br /> } else{<br /> $b=a;<br /> }
求给分!!!
------解决方案--------------------
$id = empty($_GET['id']) ? '这里是a值' : ($_GET['id']);
------解决方案--------------------
echo $id;
可以试试效果。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
