将curl与api令牌结合使用，并将XML元素放入工作变量中，或者至少以html格式查看。
以下是执行vardump:时使用的代码
$curl = curl_init('https://mywebsite.highrisehq.com/people.xml');
curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);
curl_setopt($curl,CURLOPT_USERPWD,'myapitoken12345:x');
curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,0);
$data = curl_exec($curl);
curl_close($curl);
$people_xml = new SimpleXMLElement($data);
var_dump($people_xml);
在执行var_dump时，我不熟悉输出。
object(SimpleXMLElement) #1 (2) {
["@attributes"]=> array(1) {
["type"]=> string(5) "array" }
["person"]=> array(128) { ... etc. etc. etc...
HighriseHQ.com显示的XML结构是这样的，用于提供如何检索元素的线索。
<people type="array">
<person>
<first-name>John</first-name>
</person>
<person>
<first-name>Jane</first-name>
</person>
</people>
.... etc. etc.
如何或在哪里将表示$people = simplexml_load_string($xml);的部分转换为可以使用的变量？最终，我想显示、编辑或存储这些人，因为我将用高层同步网站数据库，这样笔记和联系人就不会过时。
找到了解决方案。
$curl = curl_init('https://my_website_goes_here.highrisehq.com/people.xml');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERPWD, 'my_api_token_goes_here:x');
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
$data = curl_exec($curl);
curl_close($curl);
$people_xml = new SimpleXMLElement($data);
foreach($people_xml->person as $person) {
echo "<strong>" . $person->{'first-name'} . " " . $person->{'last-name'} . "</strong><br />";
echo "Title: " . $person->{'title'} . "<br />";
echo "Background: " . $person->{'background'} . "<br />";
echo "Email: " . $person->{'email-address'} . "<br />";
echo "ID: " . $person->id . "<br /><br />";
}
