Rest in peace PHP 5.6

The current version of PHP which is 5.6 has reached the end of life on 19th Jan 2017. PHP team has stopped support for 5.6, and no more new features added.
Security support for 5.6 is up to Jan 2019. On Jan 2019 PHP 5.6 officially dead.
The newer version of Linux and server software has already stopped supporting PHP 5.6 which creates a huge security risk.
Updating old server will be hard as it may break the PHP due to compatibility issues.
All major PHP libraries and frameworks will drop support for PHP 5.6
7.2 end of life is in Jan 2021
7.2 is so much faster than 5.6
7.X has new Zend Engine
Reduction in the memory usage
Consistent 64bit support
Better Error handling
More secure & better handling with SSL and cryptography

Symfony: Adding custom route by code during runtime

During development we always come across situation where you need to add custom routes based on some settings based from the user. In this case we cannot use any of the standard methods like annotation and configuration files in symfony.

In this case you need to use a services and hooks to inject your custom route rules during runtime.

1) In your bundles under Resources\Config\services.yml add the following

services:
  Custom.Router:
    class: [BundleNamespace]\Classes\RoutingService
    arguments: [@service_container,@request_stack]
    tags:
      - { name: routing.loader }

services:

Custom.Router:

class: [BundleNamespace]\Classes\RoutingService

arguments: [@service_container,@request_stack]

tags:

- { name: routing.loader }

2) Now we need to create a class RoutingService.php

< ?php
namespace [BundleNamespace]\Classes\Service;

use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Symfony\Component\HttpFoundation\RequestStack;
use Symfony\Component\Config\Loader\LoaderInterface;
use Symfony\Component\Config\Loader\LoaderResolverInterface;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

class RoutingService implements LoaderInterface , ContainerAwareInterface
{
    use ContainerAwareTrait;

    function __construct(ContainerInterface $container = null, RequestStack $request_stack = null)
    {
        $this->setContainer($container);
        $this->setRequestStack($request_stack);
    }

    public function load($resource, $type = null)
    {
        $routes = new RouteCollection();

        $searchRoute = new Route('/{siteSlug}/search/index.php', array(
            '_controller' => '[BundleNamespace]:[Controller]:[Action]',
        ), array(
            'siteSlug' => '[a-zA-Z0-9-]+'
        ));
        $routes->add('search_page', $searchRoute);

        return routes;
    }

    public function supports($resource, $type = null)
    {
        return 'dynamic' === $type;
    }

    public function getResolver()
    {
        // needed, but can be blank, unless you want to load other resources
        // and if you do, using the Loader base class is easier (see below)
    }

    public function setResolver(LoaderResolverInterface $resolver)
    {
        // same as above
    }
}

< ?php

namespace [BundleNamespace]\Classes\Service;

use Symfony\Component\DependencyInjection\ContainerAwareInterface;

use Symfony\Component\DependencyInjection\ContainerAwareTrait;

use Symfony\Component\DependencyInjection\ContainerInterface;

use Symfony\Component\HttpFoundation\RequestStack;

use Symfony\Component\Config\Loader\LoaderInterface;

use Symfony\Component\Config\Loader\LoaderResolverInterface;

use Symfony\Component\Routing\Route;

use Symfony\Component\Routing\RouteCollection;

class RoutingService implements LoaderInterface , ContainerAwareInterface

{

use ContainerAwareTrait;

function __construct(ContainerInterface $container = null, RequestStack $request_stack = null)

{

$this->setContainer($container);

$this->setRequestStack($request_stack);

}

public function load($resource, $type = null)

{

$routes = new RouteCollection();

$searchRoute = new Route('/{siteSlug}/search/index.php', array(

'_controller' => '[BundleNamespace]:[Controller]:[Action]',

), array(

'siteSlug' => '[a-zA-Z0-9-]+'

));

$routes->add('search_page', $searchRoute);

return routes;

}

public function supports($resource, $type = null)

{

return 'dynamic' === $type;

}

public function getResolver()

{

// needed, but can be blank, unless you want to load other resources

// and if you do, using the Loader base class is easier (see below)

}

public function setResolver(LoaderResolverInterface $resolver)

{

// same as above

}

3) Now in your main routing.yml please include these lines

custom_dynamic:
    resource: .
    type: dynamic

custom_dynamic:

resource: .

type: dynamic

4) Once you are done please make sure you clear cache both env

./app/console cache:clear
./app/console cache:clear --env=prod

1 2	./app/console cache:clear ./app/console cache:clear --env=prod

5) Now the custom route should be loaded in.. Please make sure if you add more routes make sure the cache is cleared.

WHM / cPanel – Compile PHP 5.3 to work with PHP 5.2

This is one of major issue lot of web masters face now. As PHP 5.2 has reached end of life we are forced to seek options to migrate and test PHP applications in PHP 5.2 and 5.3. Raj COO from WebHostRepo.com has posted a nice blog post on how to achieve this.

Running PHP 5.3 along with PHP 5.2.x in cPanel servers. webhostrepo

I did all the steps as mentioned on the blog post except for one, I had a lengthier configure statement 😉

9. Edit Apache conf check if “LoadModule” is present else add it.

# vi /etc/httpd/conf/httpd.conf

1	# vi /etc/httpd/conf/httpd.conf

LoadModule php5_module /usr/lib64/httpd/modules/libphp5.so

10. Set handler for Apache to handle PHP files

# vi /etc/httpd/conf/httpd.conf

1	# vi /etc/httpd/conf/httpd.conf

<FilesMatch \.php$>
    SetHandler application/x-httpd-php
</FilesMatch>

SetHandler application/x-httpd-php

</FilesMatch>

11. If you are not planning to install ZendGuardLoader skip to step 13 else make sure you have disabled SElinux. Detailed instructions

12. Install ZendGuardLoader

# cd
# wget http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz
# tar xvzf ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz
# cd ZendGuardLoader-php-5.3-linux-glibc23-x86_64/
# mv php-5.3.x/ /usr/lib64

# cd

# wget http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz

# tar xvzf ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz

# cd ZendGuardLoader-php-5.3-linux-glibc23-x86_64/

# mv php-5.3.x/ /usr/lib64

Edit /usr/local/php-5.3.19/lib/php.ini and add these lines to end

[Zend]
zend_extension="/usr/lib64/php-5.3.x/ZendGuardLoader.so"
zend_loader.enable=1

[Zend]

zend_extension="/usr/lib64/php-5.3.x/ZendGuardLoader.so"

zend_loader.enable=1

13. Restart you apache and you are set

# /etc/init.d/httpd restart

1	# /etc/init.d/httpd restart

It took a great deal of time to make this work and with lot of trial and errors. If anyone finds a better way to compile please do share it with me. All the best 😉
