BlazingCDN

Zend is a PHP framework for developing web applications that are popular in conjunction with Bootstrap. Before starting the process, there are a number of basic precautions to take:

a copy of the database and resources
selecting a HTTPS domain and securing it with the SSL protocol
creating a CDN domain in BlazingCDN Static format

To do the integration, you need to enable CDN in Zend and define CDN in Bootstrap. Then add the init function to the application / Bootstrap.php Zend file. You will do it as follows:

protected function _initCdn()
{
    Zend_Registry::set(‘cdn_enabled’, true);
    Zend_Registry::set(‘cdn_domain’, ‘cdn00000000.blazingcdn.net.’);
    Zend_Registry::set(‘cdn_protocol’, ‘http’);
}

Then create CDN helper:

class Zend_View_Helper_Cdn extends Zend_View_Helper_Abstract
{
public function cdn($url = null)
{
    $url = (string) $url;
    if(empty($url))
    {
        throw new Exception(‘URL missing’);
    }


    $pattern = ‘|^http[s]{0,1}://|i’;
    if(preg_match($pattern, $url))
    {
        throw new Exception(‘Invalid URL. ‘ .
            ‘Use: /image.jpeg instead of full URI: ‘ .
            ‘http://domain.com/image.jpeg.’
        );
    }

    $pattern = ‘|^/|’;

    if(!preg_match($pattern, $url))
    {
        $url = ‘/’ . $url;
    }

    if(!Zend_Registry::get(‘cdn_enabled’))
    {
        return $url;
    }
    else
    {
        $uri = Zend_Registry::get(‘cdn_protocol’) . ‘://’ . Zend_Registry::get(‘cdn_domain’) . $url;        return $uri;
    }
}
}

At the end use the CDN helper in views:

<? echo $this->cdn(‘/image.jpeg’); ?>

which will output:

http://cdn00000000.blazingcdn.net/image.jpeg
