Zend Framework 2 need PHP version 5.3.3?

Question

They declare PHP_VERSION>=5.3.3, however, in its code, something like 'trait' which was introduced in 5.4 appear everywhere.I'm confused!

Answer 1

It doesn't use traits, it lets you use traits. The requirement is 5.3.3, but using the traits part of the framework requires 5.4.

It doesn't break anything.

Answer 2

ZF2 has some traits and other PHP 5.4 features but are only enabled if you use PHP 5.4 else the same equivalent for PHP 5.3 is used
