Call to a non object fatal error

[alexgeek]

Hey guys, I rarely have problems with PHP but I've been using .NET for a few weeks now I've probably become a little rusty.

This is my code:

PHP: Select all

<?php
$dom = new DOMDocument();
$dom->loadHTMLFile('http://www.alexgeek.co.uk');
$slctr = new DOMTagSelector($dom);
echo $slctr->selectSingleText("//title");
class DOMTagSelector {
    private $dom;
    private $xpath;
    function __contruct($d)
    {
        $this->dom = $d;
        $this->xpath = new DOMXPath($d);
    }
    function selectSingleNode($query)
    {
        $node = $this->xpath->query($query); // line 19
        return $node;
    }
    function selectSingleText($query)
    {
        $node = $this->selectSingleNode($query);
        return $node->item(0)->nodeValue;
    }
}
?>

And the error:

Code: Select all

Fatal error:  Call to a member function query() on a non-object in C:\web\aspNETtesting\test.php on line 19

It seems the DOM object isn't passed correctly and the private properties are set to null.

A little help?

__contruct -> __construct !

(the xpath was never initialized!)

Damn my bad eyes! Good catch, thanks.
