Magento – Get current url without parameters

I also posted this question in stackoverflow and it was resolved using this solution.

function startsWith($haystack, $needle)
{
    return $needle === "" || strpos($haystack, $needle) === 0;
}

$currentUrl = Mage::helper('core/url')->getCurrentUrl();
$url = Mage::getSingleton('core/url')->parseUrl($currentUrl);
$path = $url->getPath();
if (startsWith($path, '/blog/') || (strcmp($path, '/blog') == 0))
{
    //Do something on /blog and all pages underneath
}

This are for those who are having the same problem like me. :D

To get parameter from the request use below code in a method in any class,

$param = $this->getRequest()->getParam('paramname');

To get all parameter in the request,

$params = $this->getRequest()->getParams();

Then you need to pass this to helper so forex:-

Mage::helper('modulename/helpername')->methodgettingparam($param);

if your helper is Data.php then just use 'modulename' only.

Hope this is what you need.
