我没有看到任何说明如何设置超时的文档，因此我觉得simplexml_load_file（）函数应该等待xml响应的整个加载。

在读取xml之前，您没有等待服务器的整个响应。服务器内置在Bing API中。@jdweng我使用simplexml_load_file（），正如我在编辑的问题中添加的，我不认为这应该如何部分加载xml，文档中没有提到在方法上设置任何超时。我不喜欢使用第三方API。使用以下网页上的代码获取xml：

$xml = simplexml_load_file("http://dev.virtualearth.net/REST/v1/Traffic/Incidents/37,-105,45,-94?o=xml&severity=3,4&key=#######myapikey######");
