7. Traditionally slow adopters
PHP 4 to PHP 5 was a painfully slow upgrade for the
global community
Shared hosts retained old versions
Object handling was different
PHP 5.1 on CentOS
People don’t upgrade stable systems
PHP 5.2 massive exposure
Again, people don’t upgrade stable systems
PHP 5.3 used, but not fully
8. Why slow adopters?
Shared hosts
Established applications
Upgrade path
Old excuses
9. Why adopt early?
New language features
More elegant ways to solve problems
Cleaner code
Adopting early gets you noticed
10. What about instability?
Be sensible with production-ready systems
Don’t use the bleeding edge
Confirm functionality
Unit Testing
Integration testing
Load testing
If your tests pass, then phase in the new system
Use sensible reporting / monitoring
12. PHP 5.4-RC1
RC1 was released for QA on 11th November 2011
Some new features, plenty of bug fixes
You can download it for yourself!
http://qa.php.net/
Give it a try
See if your applications run on it
29. Whats the big deal?
Elegant code re-use
Without complicated multiple inheritance
No diamond issues
Kinda like interfaces
But provides implementation
Other languages are doing similar things
PHP is keeping up with the trends
31. PHP’s approach
Traits define small sections of reusable code
This code can be included in any class
There is a loading precedence order
Puts developers in control
Looks a feels natural
No need to write things twice
Override capabilities
