PHP cURL,提取XML响应

Question

我在服务器上调用PHP cURL方法,响应是XML类型.cURL在标量类型变量中保存输出(在删除标记之后).有没有办法将它存储在一个对象/散列/数组中,以便它易于解析？

Answer 1

<?php
function download_page($path){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$path);
    curl_setopt($ch, CURLOPT_FAILONERROR,1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 15);
    $retValue = curl_exec($ch);          
    curl_close($ch);
    return $retValue;
}

$sXML = download_page('http://alanstorm.com/atom');
$oXML = new SimpleXMLElement($sXML);

foreach($oXML->entry as $oEntry){
    echo $oEntry->title . "\n";
}

Answer 2

只需header('Content-type: application/xml');在回复XML响应之前添加,您将看到一个XML页面.

例子：

<songs>
<song dateplayed="2011-07-24 19:40:26">
    <title>I left my heart on Europa</title>
    <artist>Ship of Nomads</artist>
</song>
<song dateplayed="2011-07-24 19:27:42">
    <title>Oh Ganymede</title>
    <artist>Beefachanga</artist>
</song>
<song dateplayed="2011-07-24 19:23:50">
    <title>Kallichore</title>
    <artist>Jewitt K. Sheppard</artist>
</song>

然后：

<?php
$mysongs = simplexml_load_file('songs.xml');
echo $mysongs->song[0]->artist;
?>
