Symfony 2.3 How to include Expression Language

Question

I am wondering if there is a way to include the Expression Language Component available on 2.4 version into 2.3? Or is there another rules engine available for Symfony 2? Please let me know if there is a way. Thanks!

Answer 1

2.4 is not out yet, so you can't at the moment, but later, it will be also a package as any other symfony bundle, but I would strongly suggest, that you upgrade you symfony project to 2.4 . It's scheduled to come out today.

Answer 2

I think you could simply add symfony/expression-language to your composer requirements as there are no specific requirements for this component

https://github.com/symfony/expression-language/blob/master/composer.json

"require": {
    "php": ">=5.3.3"
},
