Php 将xml对象推入数组

好的，所以我对这个有点困惑。我有一个xml，看起来像这样：

<track>
<artist mbid="77cceea7-91bb-4a4c-ae41-bc9c46c1ccb5"> Red Hot Chili Peppers </artist>
<name> under the bridge </name>
<streamable>0</streamable>
<mbid/>
<album mbid="0fe94139-df63-4e51-b2e7-a1d53535cdd9">  Blood Sugar Sex Magik </album>
<url> http://xxxxxx.com </url>
<date uts="1351691244">31 Oct 2012, 13:47</date>
</track>

$artists = array();

$xml = simplexml_load_file("http://xxxxxxxxxxxxxx");

foreach($xml->recenttracks->track  as $track)
{
$artist = $track->artist;
    array_push($artists, $artist);
}  

var_dump($artists);

array(4) {
[0]=>
string(20) "Red Hot Chili Peppers "
[1]=>
string(20) "Red Hot Chili Peppers"
}

array(2) 
{ 
[0]=> object(SimpleXMLElement)#6 (2) { ["@attributes"]=> array(1) { ["mbid"]=> string(36) "8bfac288-ccc5-448d-9573-c33ea2aa5c30" } [0]=> string(21) "Red Hot Chili Peppers" } 
[1]=> object(SimpleXMLElement)#4 (2) { ["@attributes"]=> array(1) { ["mbid"]=> string(36) "8bfac288-ccc5-448d-9573-c33ea2aa5c30" } [0]=> string(21) "Red Hot Chili Peppers" } 
} 

现在我希望得到一个像这样的漂亮阵列：

<track>
<artist mbid="77cceea7-91bb-4a4c-ae41-bc9c46c1ccb5"> Red Hot Chili Peppers </artist>
<name> under the bridge </name>
<streamable>0</streamable>
<mbid/>
<album mbid="0fe94139-df63-4e51-b2e7-a1d53535cdd9">  Blood Sugar Sex Magik </album>
<url> http://xxxxxx.com </url>
<date uts="1351691244">31 Oct 2012, 13:47</date>
</track>

$artists = array();

$xml = simplexml_load_file("http://xxxxxxxxxxxxxx");

foreach($xml->recenttracks->track  as $track)
{
$artist = $track->artist;
    array_push($artists, $artist);
}  

var_dump($artists);

array(4) {
[0]=>
string(20) "Red Hot Chili Peppers "
[1]=>
string(20) "Red Hot Chili Peppers"
}

array(2) 
{ 
[0]=> object(SimpleXMLElement)#6 (2) { ["@attributes"]=> array(1) { ["mbid"]=> string(36) "8bfac288-ccc5-448d-9573-c33ea2aa5c30" } [0]=> string(21) "Red Hot Chili Peppers" } 
[1]=> object(SimpleXMLElement)#4 (2) { ["@attributes"]=> array(1) { ["mbid"]=> string(36) "8bfac288-ccc5-448d-9573-c33ea2aa5c30" } [0]=> string(21) "Red Hot Chili Peppers" } 
} 

但我得到的是这样的东西：

<track>
<artist mbid="77cceea7-91bb-4a4c-ae41-bc9c46c1ccb5"> Red Hot Chili Peppers </artist>
<name> under the bridge </name>
<streamable>0</streamable>
<mbid/>
<album mbid="0fe94139-df63-4e51-b2e7-a1d53535cdd9">  Blood Sugar Sex Magik </album>
<url> http://xxxxxx.com </url>
<date uts="1351691244">31 Oct 2012, 13:47</date>
</track>

$artists = array();

$xml = simplexml_load_file("http://xxxxxxxxxxxxxx");

foreach($xml->recenttracks->track  as $track)
{
$artist = $track->artist;
    array_push($artists, $artist);
}  

var_dump($artists);

array(4) {
[0]=>
string(20) "Red Hot Chili Peppers "
[1]=>
string(20) "Red Hot Chili Peppers"
}

array(2) 
{ 
[0]=> object(SimpleXMLElement)#6 (2) { ["@attributes"]=> array(1) { ["mbid"]=> string(36) "8bfac288-ccc5-448d-9573-c33ea2aa5c30" } [0]=> string(21) "Red Hot Chili Peppers" } 
[1]=> object(SimpleXMLElement)#4 (2) { ["@attributes"]=> array(1) { ["mbid"]=> string(36) "8bfac288-ccc5-448d-9573-c33ea2aa5c30" } [0]=> string(21) "Red Hot Chili Peppers" } 
}

现在，我如何仅获取艺术家，而不是整个SimpleXMLElement，因为我无法理解它。

var\u dump提供了可以用于访问不同片段的键，而强制转换到字符串将只提供节点值，请尝试：

$artist = (string) $track->artist[0];

---

看看这些链接。。。他们过去帮助过我

请尝试下面的代码

$xml = simplexml_load_file("artist.xml");

echo $xml->artist;

---

要添加到数组中的项是

simplexmlement

s。如果只想添加字符串值，则必须将

simplexmlement

强制转换为字符串

$artists = array();
foreach($xml->recenttracks->track  as $track)
{
    $artists[] = (string) $track->artist;
}  

var_export($artists);

通常，当需要字符串值时，总是希望将

simplexmlement

强制转换为字符串。在某些情况下，PHP会自动强制为字符串（例如，当您

echo

it时），但PHP类型强制规则非常复杂，最好始终是显式的

---

（另外，不需要

array_push（）

，只需使用括号符号

$arrayname[]=$appendedvalue

）

如果我只回显艺术家，我只会得到艺术家的名字，但如果我把它推到数组中，我会得到所有这些额外的信息。在描述中忘了提到这一点。@user1593846-令人困惑的是，您没有发布完整的XML文档，只有一个节点。有关如何访问该值，请参见我的答案。
