Menu
I have several functions in a class that return saveHTML(). After I echo more than one function in the class saveHTML(), it repeats some of the HTML. I initially solved this by doing saveHTML($node) but that doesn't seem to be an option now.
I didn't know saveHTML($domnode) was only available in PHP 5.3.6 and I have no control over the server I uploaded the files to so now I have to make it compatible with PHP 5.2.
For simplicity's sake it and only to show my problem it looks similar to this:
<?php
class HTML
{
private $dom;
function __construct($dom)
{
$this->dom = $dom;
}
public function create_paragraph()
{
$p = $this->dom->createElement('p','Text 1.');
$this->dom->appendChild($p);
return $this->dom->saveHTML();
}
public function create_paragraph2()
{
$p = $this->dom->createElement('p','Text 2.');
$this->dom->appendChild($p);
return $this->dom->saveHTML();
}
}
$dom = new DOMDocument;
$html = new HTML($dom);
?>
<html>
<body>
<?php
echo $html->create_paragraph();
echo $html->create_paragraph2();
?>
</body>
</html>
Outputs:
<html>
<body>
<p>Text 1.</p>
<p>Text 1.</p><p>Text 2.</p>
</body>
I have an idea why it's happening but I have no idea how to not make it repeat without saveHTML($domnode). How can I make it work properly with PHP 5.2?
Here's an example of what I want to be able to do:

What I do, is just save the node as XML. There are a few differences in the syntax, but it's good enough for most uses:
return $dom->saveXml($node);
