我正在try 用php将xml转换为json.如果我使用简单的xml和json进行简单的转换，那么xml显示中的所有属性都不会被编码.
$xml = simplexml_load_file("states.xml");
echo json_encode($xml);
所以我试着像这样手动解析它.
foreach($xml->children() as $state)
{
$states[]= array('state' => $state->name);
}
echo json_encode($states);
并且state的输出是{"state":{"0":"Alabama"}}而不是{"state":"Alabama"}
我做错了什么？
XML:
<?xml version="1.0" ?>
<states>
<state id="AL">
<name>Alabama</name>
</state>
<state id="AK">
<name>Alaska</name>
</state>
</states>
输出:
[{"state":{"0":"Alabama"}},{"state":{"0":"Alaska"}
变量转储:
object(SimpleXMLElement)#1 (1) {
["state"]=>
array(2) {
[0]=>
object(SimpleXMLElement)#3 (2) {
["@attributes"]=>
array(1) {
["id"]=>
string(2) "AL"
}
["name"]=>
string(7) "Alabama"
}
[1]=>
object(SimpleXMLElement)#2 (2) {
["@attributes"]=>
array(1) {
["id"]=>
string(2) "AK"
}
["name"]=>
string(6) "Alaska"
}
}
}
