我正在使用一个scorm测试，它可以将数据作为xml导出到我的服务器。我正在尝试解析这些数据，以便使用其中的一些数据发送到php电子邮件中。我现在尝试的是返回数字1，但我不知道如何使其工作。帮助
<?php
$version = $_POST['v'];
$points = $_POST['sp'];
$passing_percent = $_POST['psp'];
$gained_score = $_POST['tp'];
$username = $_POST['sn'];
$email = $_POST['se'];
$quiz_title = $_POST['qt'];
$detailed_results_xml = $_POST['dr'];
$xml_string = <<<_XML
print "<?xml version="1.0" encoding="iso-8859-1"?>" . $detailed_results_xml;
_XML;
$xml = simplexml_load_string($xml_string);
$emailtest = print_r($xml);
mail("email@email.com",$quiz_title,$emailtest,"From: fromname <noreply@test.com>");
?>
如果我通过电子邮件将$detailed_results.xml发送给自己，它的显示方式如下：

<direction>Exercise 2:!
Regulate the Body’s Clock through Daily Routine
Some people use a morning routine to help them wake up and a bedtime routine of relaxing activities to prepare their bodies for sleep. These activities of daily living act as “cues†to signal the brain to fall into biological rhythms.
In this exercise, consider for a minute what you did last night before bed and what you’ve done so far today.
Take a moment to describe your daily routine and activities starting with last night.

很抱歉，如果xml的格式搞砸了，但我认为你应该从中得到想法。因此，xml位是由$detailed_results.xml生成的，我需要将其中的一些部分解析为html以发送到电子邮件中，但现在我只看到一个数字1。非常感谢您的帮助！
print_r返回1（整数）。您必须传递第二个布尔参数，它才能返回字符串。
线路是：
$emailtest = print_r($xml);
这就是为什么您将1作为邮件的$message参数。可能你发送了错误的信息（email（）第三个参数），我想你会想：
mail("email@email.com", $quiz_title, $xml, "From: fromname <noreply@test.com>");
解析XML有很多方法：
