一个接口,能得到返回的xml文件,如何提取有用的内容?
接口调用后,$result= 能得到以下内容:

stdClass Object
(
    [out] => 

 
 




T

)


以前做这直接读取 xml的,可这种带了一个stdClass Object(  [out] =>

不知道应该如何读到各节点内容了


------解决方案--------------------
如果你对对象操作不熟悉,可以先转换为数组,这样会方便一些。
你获取的对象很简单, $result->out 就是这个XML字符串,若是想提取其中的内容,可以尝试字符串提取,或者解析XML为对象再转数组(推荐)。

------解决方案--------------------
直接打印
echo $result->out;

作为xml解析
$xml = simplexml_load_string($result->out);
print_r($xml);
SimpleXMLElement Object<br>(<br>    [flights] => SimpleXMLElement Object<br>        (<br>            [flight] => SimpleXMLElement Object<br>                (<br>                    [@attributes] => Array<br>                        (<br>                            [orgCity] => SHA<br>                            [departTerm] => T2<br>                            [dstCity] => CAN<br>                            [arrivalTerm] => --<br>                            [airComp] => MU<br>                            [flightno] => MU5307<br>                            [planeType] => 320<div class="clear">
                 
              
              
        
            </div>

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
