PHP调用C#Webservice如果判断是否有数据呢?


回复讨论(解决方案)

$obj_xml = simplexml_load_string($result);
print_r($obj_xml);

你的代码是可以的
说说有什么疑问

我的意思是,如果当天航班停班了,这个就没有航班数据,
如果没有数据,foreach($obj_xml->NewDataSet->Table1 as $item) 这里会报错.
Warning: Invalid argument supplied for foreach() in D:\xampp\htdocs\WS\index.php on line 137

if(isset($obj_xml->NewDataSet->Table1)) foreach($obj_xml->NewDataSet->Table1 ....

if(is_array($obj_xml->NewDataSet->Table1))  foreach($obj_xml->NewDataSet->Table1 ....

if(isset($obj_xml->NewDataSet->Table1)) foreach($obj_xml->NewDataSet->Table1 ....

if(is_array($obj_xml->NewDataSet->Table1))  foreach($obj_xml->NewDataSet->Table1 ....


if(isset($obj_xml->NewDataSet->Table1))  可以
if(is_array($obj_xml->NewDataSet->Table1))  不行,原本有数据也不显示了,我之前也是用if(is_array($obj_xml->NewDataSet->Table1)) 发现不行,才上来发贴,能解释一下is_array不能的原因吗?$obj_xml->NewDataSet->Table1确实是数组呀?不是很明白?

嗯,那是对象,不是数组
echo gettype($obj_xml->NewDataSet->Table1); // object
但 count 可以正确的返回成员个数
echo count($obj_xml->NewDataSet->Table1); //87
