Call to undefined function domxml_new_doc()

YourDirector

Hi everyone,

I'm pretty new to PHP and completely new to the use of XML files. I am currently trying to create a document with the following code:

<?php
$doc = domxml_new_doc("1.0");
$root = $doc->create_element("article");
$root = $doc->append_child($root);

But it keeps on coming up with this error:

Call to undefined function domxml_new_doc() in /homepages/29/d278322091/htdocs/inspire/addArticle.php on line 3

I have read on some forums saying that I need to check if the php_domxml.dll file is in the PHP directory but I'm not 100% what they mean by that. I'm hosted on 1&1 and have checked that it is currently running PHP5.

Any help would be much appreciated. Thanks :-)

Ooh, I must amend that and point out it is line 2 it is referring to as I removed:

//create document root

from the code

Call to undefined function domxml_new_doc means that there is no function called domxml_new_doc, which in turn means you can't call it.

Some functions are built into php, others require you to compile php on your own with certain options set. The documentation at php.net will tell you what is required in each case.

Considering that [man]domxml_new_doc[/man] states

(PHP 4 >= 4.2.0)

Rather than just PHP >= 4.2.0 or PHP 4, PHP 5.

This means that unless you are running PHP 4, whose production cycle has ended = DON'T, you will not have access to any of the functions listed at [man]domxml[/man]. However, if you look at the menu in the left column, above DOM XML (PHP 4) is DOM, which doesn't have (PHP 4) next to it. Use that instead... Also note that when you look at any of the functions in [man]DOM[/man], it says (PHP 5) at the top of each of those pages.

Hi Johanafm,

Thanks for the reply. If I understand correctly, PHP 4 is now redundant and shouldn't be used but that PHP 5 doesn't support the function domxml_new_doc.

So, if I were to be using PHP 5, would the direct equivalent be:

DOMDocument::__construct

Thanks for this

Oddly, I just tried running it again, without changing anything and it worked fine.

Then I tried again straight after, again without changing a thing and it went back to the old error message :-s

Yes. But the constructor is automatically called when you create a new instance of the class

$d = new DOMDocument();
