Upgrade Guide

Upgrading to V5

So you have decided to upgrade to v5! Congratulations!!

Phalcon v5 contains a lot of changes in components and interfaces. Upgrading is going to be a time-consuming task, depending on how big and complex your application is. We hope that this document will make your upgrade journey smoother and also offer insight as to why certain changes were made and how it will help the framework in the future.

We will outline the areas that you need to pay attention to and make necessary changes so that your code can run as smoothly as it has been with v4. Although the changes are significant, it is more of a methodical task than a daunting one.

Requirements

PHP 7.4

Phalcon v5 supports only PHP 7.4 and above. PHP 7.4 active support expired roughly a month before the release of Phalcon 5, but support for security patches etc. will continue until November 2022. After that time, we will drop support for PHP 7.4 also.

Since Phalcon 4, we have been following the PHP releases and adjusting Phalcon accordingly to work with those releases.

Installation

Phalcon can be installed using PECL.

pecl install phalcon-5.0.0

Alternative installation

Download the latest zephir.phar from here. Add it to a folder that can be accessed by your system.

Clone the repository

git clone https://github.com/phalcon/cphalcon

Compile Phalcon

cd cphalcon/
git checkout tags/5.0.0 ./
zephir fullclean
zephir build

You will need to add the following line to your php.ini (in some cases both the CLI and web versions of it)

extension=phalcon.so

Check the module

php -m | grep phalcon

If the above does not work, check the php.ini that your CLI is looking for. If you are using phpinfo() and a web browser to check if Phalcon has been loaded, make sure that your php.ini file that your web server is looking for contains the extension=phalcon.so. You will need to restart your web server after you added the new line in php.ini.

General Notes

One of the biggest changes with this release is that we no longer have top level classes. All top level classes have been moved into relevant namespaces (except Phalcon\Tag). For instance Phalcon\Loader has been moved to Phalcon\Autoload\Loader. This change was necessary for the future expansion of the project.

addCss() now requires $local to be bool and $attributes to be an array

public function addCss(
    string $path,
    bool $local = true,

Autoload

The Autoload\Loader component has been moved from the parent namespace. Some method names have been changed and new functionality introduced.

`Phalcon\Autoload\Loader`

__construct(bool $isDebug = false) The constructor now accepts a boolean, which allows the loader to collect and store debug information during the discovery and loading process of files, classes etc. If the variable is set to true, getDebug() will return an array with all the debugging information during the autoload operation. This mode is only for debugging purposes and must not be used in production environments.

use Phalcon\Autoload\Loader;
use Adapter\Another;

$loader = new Loader(true);

$loader
    ->addNamespace('Base', './Namespaces/Base/')
    ->addNamespace('Adapter', './Namespaces/Adapter/')
    ->addNamespace('Namespaces', './Namespaces/')
;

$loader->autoload(Another::class);

var_dump($loader->getDebug());

// [
//     'Loading: Adapter\Another',
//     'Class: 404: Adapter\Another',
//     'Require: 404: ./Namespaces/Adapter/Another.php',
//     'Require: ./Namespaces/Another.php',
//     'Namespace: Namespaces\Adapter - ./Namespaces/Another.php',
// ];

The main difference is that a Phalcon\Html\TagFactory has to be set in the form object, so that elements can be rendered. If the Phalcon\Html\TagFactory is not set, then the component will search the Di container (Phalcon\Di\DiInterface) for a service with the name tag. If you are using Phalcon\Di\FactoryDefault as your container, then the tag service is already defined for you.

`Phalcon\Support\Collection`

Added __call() in Phalcon\Support\Helper\HelperFactory to offer an easier access to objects i.e. $this->helperFactory->dirFromFile()

Volt

Since the tag service has changed from Phalcon\Tag to Phalcon\Html\TagFactory several helper methods used in Volt have changed also. The biggest change is the form() helper in Volt.

If you wish to keep your Volt code the way it is, without changing method signatures, you will have to rename your form() calls to formLegacy(). formLegacy() will use the Phalcon\Tag component as before. However, if you wish to use the new Phalcon\Html\TagFactory component, you can keep the method call as is (i.e. form() but you will need to change the signature of the helper method. more…
