Simple DOM Helper

[eluser]K.Brown[/eluser]
I'm trying to use the simple DOM helper, but I'm having some trouble.

I'm new to CI and PHP. This seems to be an error due to my server setup...

Code:

<?php

class Welcome extends Controller
{

    function __construct()
    {
        parent::Controller();
        $this->load->helper('dom');
    }

    public function index()
    {
        // Grab HTML From the URL
        $html = file_get_html('http://codeigniter.com/');

        // find all link on Codeigniter Site
        foreach($html->find('a') as $e)
        echo $e->href . '<br>';
    }
}

This is the output:

A PHP Error was encountered

Severity: Warning

Message: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration

Filename: helpers/dom_helper.php

Line Number: 40

A PHP Error was encountered

Severity: Warning

Message: file_get_contents(http://codeigniter.com/) [function.file-get-contents]: failed to open stream: no suitable wrapper could be found

Filename: helpers/dom_helper.php

Line Number: 40

What can I do to fix this?

I had this same problem on Media Temple. What I did to solve it was to load the page using cURL and save it as a variable and then use the str_get_html function to parse the saved variable. I don't know if this is the best solution, but it worked. If you want more a code example I could post it tonight when I'm home from work.

An example would be great!

I'm only familiar with the echo function...lol.

Sorry for the long delay!

Here's how I'm using cUrl and SimpleDomHelper together:

Code:

function html_example() {
        $this->load->helper('simple_html_dom');
        
        //url to be loaded through cURL
        $url = 'http://www.google.com';
        
        //initiate cURL and save data to $content
        $ch = curl_init ();
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt ($ch, CURLOPT_URL, $url);
        curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
        $content = curl_exec ($ch);
        curl_close ($ch);
        
        //parse $content with simple_html_dom
        $html = str_get_html($content);
        
        //echo out all hyperlinks found
        foreach($html->find('a') as $element) {
                       echo $element->href;
       }
}

Hope this helps! If anyone has any suggestions for improvement, please let me know.
