如何获取页面内容。
当我输入一个URL时，URL返回在页面的内容。我如何遍历出来。
比如：www.cdn.net/uid=1
然后页面内将显示.uid=1 uname=2
uid=2 uname=3
uid=3 uname=4
我如何将它遍历出来。。。求代码。
我已经用file_get_contents整到手了。就是还没遍历~

------解决方案--------------------
$obj = json_decode($str);
echo $obj->server_info->server_number;

类似的自己搞吧....google一下，然后自己动手能学到很多知识，比等着别人告诉你要强...

Dependency 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.
