a php script to look at the android play store for the given package name, and find out its category.

PackageCategory.php

<?php

class PackageCategory
{
	
  protected static $playurl = 'https://play.google.com/store/apps/details?id=';
	
  public function PackageCategory($packageName) {
        $this->packageName = $packageName;
    }

    public function getPackageCategory()
    {    	
		$result = $this->makeRequest(self::$playurl.$this->packageName);		
		//starting index of category tag
		$indexstart = strpos($result,"<span itemprop=\"genre\">");
		
		//ending index of category tag
		$indexend = strpos($result,"</span>",$indexstart);
			
		$category = substr($result,$indexstart+23,$indexend - ($indexstart+23));
		echo $category;
    }

//curl to the play store
 /**
     * Makes request to AWIS
     * @param String $url   URL to make request to
     * @return String       Result of request
     */
    protected function makeRequest($url) {
        //echo "\nMaking request to:\n$url\n";
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_TIMEOUT, 4);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $result = curl_exec($ch);
        curl_close($ch);
        return $result;
    }
    
}

    
    if (count($argv) < 2) {
    echo "Usage: $argv[0] PackageName\n";
    exit(-1);
}
else {
    $packageName = $argv[1];   
}

$packageCategory = new PackageCategory($packageName);
$packageCategory->getPackageCategory();
    
 ?>

It Works Great , But I want to know that is it safe to use? secondly will google block the IP of the site from where i am sending this link ?
