php中simplexml_load_file()函数用法详细

// The file test.xml contains an XML document with a root element
// and at least an element /[root]/title.

if (file_exists('test.xml')) {
    $xml = simplexml_load_file('test.xml');

    var_dump($xml);
} else {
    exit('Failed to open test.xml.');
}
?> 

This script will display, on success:

SimpleXMLElement Object
(
  [title] => Example Title
  ...
)
 

header("content-type:text/html; charset=utf-8"); //设置编码
$xml = simplexml_load_file('a.xml');  //载入xml文件 $lists和xml文件的根节点是一样的
echo $xml->company."
";
echo $xml->town."
id:";
echo $xml->town['id']."
parent:";
echo $xml->town['parent']."
";

echo "
循环读取:
";
foreach($xml->user as $users){     //有多个user，取得的是数组，循环输出
    echo "-------------------
";
    echo "姓名:".$users->name."
";
    echo "编号:".$users->age."
";
    echo "性别:".$users->age['sex']."
";
    echo "序号:".$users->height."
";
}

echo "
循环读取:
";
foreach($xml->town as $towns){     //有多个user，取得的是数组，循环输出
    echo "-------------------
";
    echo "id:".$towns['id']."
";
    echo "归属:".$towns['parent']."
";
    echo "地区:".$towns."
";
}
