PHP - XML Simple XML

[jleajones]

I am trying to pull data from an xml file using the simplexml functions.

I have been able to retrieve all the information except one field. The field is titled tickets-URL.

When i try to do echo $event->tickets-URL, i get a notice that say use of undefined constant URL, assumed 'URL'.

I turned off notices in my php.ini file but it does not display the field. I just don't get the error. Any help would be appreciated being that I need the data in that field.

Thanks in advance.

It would be good to see a least some of the XML as well as the code that is suppose to read the XML.

It's likely some small thing but there is no way to tell till we can look at it.

Below is a sample of the XML code.

<?xml version="1.0" encoding="utf-8"?>
<event>
  <VIP-URL nil="true"/>
  <active type="boolean">true</active>
  <ages nil="true"/>
  <close type="datetime">2000-01-01T03:00:00+00:00</close>
  <closed-message nil="true"/>
  <cover nil="true"/>
  <created-at type="datetime">2010-09-20T00:18:37+00:00</created-at>
  <date type="date">2010-10-29</date>
  <description nil="true"/>
  <guestlist-URL nil="true"/>
  <guestlist-conditions nil="true"/>
  <home-URL nil="true"/>
  <id type="integer">9434</id>
  <myspace-URL nil="true"/>
  <open type="datetime">2000-01-01T22:00:00+00:00</open>
  <public-guestlists type="boolean">true</public-guestlists>
  <tickets-URL>yes</tickets-URL>
  <tickets-sold-count type="integer">0</tickets-sold-count>
  <time type="datetime" nil="true"/>
  <title>Halloween with DJ Spider</title>
  <updated-at type="datetime">2010-09-21T21:46:31+00:00</updated-at>
  <wiki-name nil="true"/>
</event>

I have been able to retrieve the value in all the fields I have needed thus far using the simplexml parser. Something like below below:

/*This returns the something like above...*/
$xml_event = simplexml_load_file($BASE_URL.'venues/'.$venue.'/events/'.$eventid.".xml".$login);

$event = $xml_event->children();
echo $event->id;
echo $event->title;
echo $event->open;
echo $event->tickets-URL;

Everything prints except the tickets-url. I actually have this problem with every key with ''url' appended to the end. Any help would be greatly appreciated.

THanks.

That's because $event->tickets-URL is not one variable, it's one variable - undefined constant

$ticket = 10;
define('URL, 6);
echo $ticket-URL;    # 4

You need to

$event->{'tickets-URL'};

Or preferably, use underscore rather than hyphens in your xml file

<tickets_URL>yes</tickets-URL>

which lets you

$event->tickets_URL;

I totally agree with the XML idea, however I'm getting the data from a third party site. But the PHP tip really helped and worked like a charm. THanks, because I can def use that knowledge elsewhere being that a lot of the XML fields have ' - ' instead of ' _ '.
