如何使用 PHP 从 json/xml 中的@attributes 获取数据

Question

我在 @attributes 中拥有所有 JSON 数据，并希望使用 PHP 将其提取到变量中。
我正在尝试什么：

$url = "http://synd.cricbuzz.com/j2me/1.0/livematches.xml";
$xml = simplexml_load_file($url) or die("Error..");
$json = json_encode($xml, JSON_PRETTY_PRINT);
$decode_json = json_decode($json);
$match = $decode_json->match[0];
print_r($match);

这是我使用上述代码得到的输出：http://phpfiddle.org/main/code/3zbq-62w0
任何帮助将不胜感激。谢谢..

Answer 1

您可以使用simple_xml 库附带的attributes 函数。它返回一个SimpleXMLElement，它实现了Traversable接口，这意味着你可以遍历：

<?php
$url = "http://synd.cricbuzz.com/j2me/1.0/livematches.xml";
$xml = simplexml_load_file($url) or die("Error..");
$match_attributes = $xml->match->attributes();

foreach ($match_attributes as $k => $v) {
    printf('%s => %s<br />', $k, $v);
}
?>

现在获取数据很容易。

id => 4
type => T20
srs => Bangladesh tour of Sri Lanka, 2017
mchDesc => SL vs BAN
mnum => 1st T20I
vcity => Colombo
vcountry => Sri Lanka
grnd => R.Premadasa Stadium
inngCnt => 1
datapath => http://synd.cricbuzz.com/j2me/1.0/match/2017/2017_SL_BAN/SL_BAN_APR04/

@Sukhchain Singh 只需尝试以下一个：

<?php
    $yourArray = json_encode($yourJson, true);
    /* suppose you got $yourArray = array(
                            "@attributes" => array(
                            "id" => 4,
                            "type" => "T20",
                            "srs" => "Bangladesh tour of Sri Lanka, 2017",
                            "mchDesc" => "SL vs BAN",
                            "mnum" => "1st T20I",
                            "vcity" => "Colombo",
                            "vcountry" => "Sri Lanka",
                            "grnd" => "R.Premadasa Stadium",
                            "inngCnt" => 1,
                            "datapath" => "http://synd.cricbuzz.com/j2me/1.0/match/2017/2017_SL_BAN/SL_BAN_APR04/"
                        )
                    );
         */
extract($yourArray["@attributes"]); // it will extract all the element as a variable
echo $id;
