使用PHP解析XML以返回数字1的电子邮件

Question

I am using a scorm quiz that can export data to my server as xml. I am trying to parse that data so that I can use some of it to send in a php email. What I am trying right now returns the number 1 and I can't figure out how to make it work. Help?

<?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("[e-mail]",$quiz_title,$emailtest,"From: fromname <[e-mail]>");

?>

If I email the $detailed_results_xml to myself it comes through like this:

<quizReport xmlns="http://www.ispringsolutions.com/ispring/quizbuilder/quizresults"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://www.ispringsolutions.com/ispring/quizbuilder/quizresults  quizReport.xsd" version="1">

    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.

Sorry if the formatting got messed up on the xml bit but you should get the idea from it I think. So the xml bit is what gets generated by $detailed_results_xml and I need to parse some pieces of it to html to send in an email, but right now I am only seeing a number 1. Any help is greatly appreciated!

Answer 1

print_r return 1 (as integer). You must pass a second boolean parameter for it to return a string.

the line is:

$emailtest = print_r($xml);

That is why you're getting 1 as the $message parameter for mail. And probably you are sending the wrong message (email() 3rd parameter), I think you wold want to:

mail("[e-mail]", $quiz_title, $xml, "From: fromname <[e-mail]>");

For parsing the XML there are many ways :

functions

object oriented
