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] =>
?
?
)
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>

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
