About me
- 10+ years in IT: Java, PHP, JavaScript etc.
- Writer, speaker.
- OpenSource.
- Yii core team member, PHP-FIG representative.
- In the past worked with Siemens, Wrike, CleverTech, Stay.com.
- Currently team lead at Skyeng.
We are going to talk about
- PHP.
- Where is it heading to.
- What to learn?
- Which framework to choose next?
- Yii.
The talk is mainly for the ones learning.
Let's start with PHP
Where is PHP heading to?
But first a bit about languages in general
What's the difference between languages?
Users
- Novice.
- Specialist.
- Professional.
- ...
There are almost no all-stars IT-teams when it comes to real business. You need a language for novices.
Novices need
- Frames (guidelines, limitations).
- Strictness.
- Examples.
- Java is for novices.
- Python is for experienced.
- JavaScript...
Features are less important
When developing for web we're more assemblying things rather than developing.
If we need something
unique (often quick-performing) we can do it as golang microservice.
Paradigm is important!
Projects
- Just for fun.
- Own projects for $.
- Teams for $.
- Many teams for $.
PHP improvements over years
PHP 7.0
- Performance.
- More exceptions.
- Return types and scalar typehints.
- assert().
- Security.
- phpdoc is always cached (annotations).
PHP 7.1
- nullable types.
- void return.
- Constant visibility (private, protected, public).
- pcntl_async_signals.
PHP 7.2
- object as typehint.
- More security.
- Syntactic sugar.
PHP 7.3
- is_countable().
- Syntactic sugar.
Why?
Is PHP okay?
It is!
- Somewhere between "for novice" and "for fun".
- Frameworks could shift above position.
- Teamleads and tools are watching.
- Allows prototyping fast.
- Infrastrutcutre is great! Composer.
- stateless by default.
What to learn?
Learn what you can use anywhere
- OOP/OOD. Check yourself with cohesion/coupling.
- HTTP/HTTPS/REST.
- Security.
- SQL.
- CAP (Consistency-Availability-Partition Tolerance).
- Basic undestanding of algorithm complexity.
- Refactoring.
- Linux.
You still should learn the framework you use!
Business needs
- Predictability.
- Performance.
- Adequate cost.
- Ability to express yourself clearly.
- Ability to write dirty code quickly.
- Ability to estimate.
- Desire to learn new things.
Which framework to choose next?
What do we have?
- Laravel.
- Symfony.
- Yii 2.
- CakePHP.
- CodeIgniter.
- Zend Framework.
- reactphp.
- Phalcon.
- FuelPHP.
- Slim, F3, ...
Laravel
- Excellent marketing. Most popular framework nowadays.
- Secret priorities similar to Apple.
- Questionable community relations.
- It's alright.
Symfony
- Strong limitations.
- Performance issues are being solved by caching and compiling (OroCRM).
- It better if cache works well. Debug isn't easy. There are many layers.
- Style is similar to Java and Spring.
Zend Framework
Similar to Symfony. Too similar.
Phalcon
- Way better perforance.
- Can't dig into it easily. It is PECL.
ReactPHP
Great for async daemons.
Web studio
- Wordpress.
- Drupal.
- ...
Some studios create their own CMS with frameworks.
What do you really need from a framework?
It should be enjoyable.
What about no framework approach?
Do you have enough experience and time?
- You'll build a framework anyway.
- Each library is OK by itself but how about 10 libraries used together?
- How to teach your team?
- Deadlines... yesterday?
Try it. We succeeded in making a framework ;)
Don't get stuck with a single language or framework
- PHP MVC.
- Rapid development.
- You can get from MVP to support and development.
- Lots of features out of the box.
- Flexible and pragmatic.
- Allows taking shortcuts.
- Non-commerial.
Some stats
- Slack, 957 users.
- 392 projects at YiiPowered.
- 12017 Github stars.
- 32027 Facebook group members.
Yii philosophy
- Complexity should be enough and not more than that.
- API and code usability first.
- Document everything.
- Backwards compatiblity and support are important.
- Listen to your community.
- OpenSource is working together on something we all benefit from.
Same as with every framework Yii has its pros and cons.
- RAD
- Not too strict
- Thin abstractions
- Performance
- ...
Yii 2.0 mistakes
Tried to handle too much
Got too much into the core.
- jQuery.
- PJAX.
- CAPTCHA.
- Masked input.
- More clientside :(
fxp composer plugin
Gave many issues. Both good and bad.
We haven't used many PSRs
They were mostly accespted after framework release. Backwards compatibility...
next?
- New website (OpenSource).
- Infrastructure imrovements.
- ActiveRecord and DB layer internals were refactored.
- Got feedback at Trello.
- Yii 2.0 is feature frozen.
- Yii 2.1 in progress.
- yiisoft/di.
- Still supporting 1.1.
We need your help!

- Баги, фидбек, идеи, код.
