I recently need to get the number of views a Stumbleupon submission had received, and decided to write a small little helper class. I thought I would offer it up as someone else might find it useful for displaying the number of views their article got on Stumbleupon or whatever else.
I suggest if you use it with Codeigniter, drop it into your libraries folder and use it that way. Copy and paste the below code to a new PHP file. There is an example at the end of the file for it's use.
Code:
<?php
/*
* This script will fetch the number of views a particular URL has received (if it is on StumbleUpon).
* Script created by: Dwayne - http://www.ilikekillnerds.com
*/
class Stumbleviews {
private $curl;
private $userAgent = "Googlebot/2.1 (http://www.googlebot.com/bot.html)";
private $targetUrl = "http://www.stumbleupon.com/url/";
private $useCurl = true;
public function __construct() {
}
public function set_useragent($useragent)
{
$this->userAgent = $useragent;
}
public function set_method($method)
{
if ($method == 'curl') {
$this->useCurl = true;
}
if ($method == 'file') {
$this->useCurl = false;
}
}
public function set_url($url) {
$this->targetUrl = $this->targetUrl . trim($url);
}
public function fetch_views() {
if ($this->useCurl == true) {
$this->_prep(); // Setup our curl options
$html = curl_exec($this->curl);
} else {
$html = file_get_contents($this->targetUrl);
}
$dom = new DOMDocument();
@$dom->loadHTML($html);
// New XPath for querying our HTML
$xpath = new DOMXPath($dom);
$views = $xpath->evaluate("//div[@class='views']//a[@href='$this->targetUrl']");
// Return the number of views
for ($i = 0; $i < $views->length; $i++) {
$view = $views->item($i)->nodeValue;
return $view;
}
}
private function _prep()
{
$this->curl = curl_init();
curl_setopt($this->curl, CURLOPT_URL, $this->targetUrl);
curl_setopt($this->curl, CURLOPT_USERAGENT, $this->userAgent);
curl_setopt($this->curl, CURLOPT_FAILONERROR, true);
curl_setopt($this->curl, CURLOPT_HEADER, 1);
curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($this->curl, CURLOPT_AUTOREFERER, true);
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($this->curl, CURLOPT_TIMEOUT, 10);
}
}
/**
* Example code shown below
* We do not provided the www. or anything else
* you only need to provide the site and extension
* as you can see below for google all we need is
* google.com
*
$stumbleviews = new Stumbleviews();
$stumbleviews->set_url('google.com');
echo $stumbleviews->fetch_views();

?>
