问题 I've seen plenty of comparisons of Doctrine vs Propel, but none of them has actually convinced me to choose Doctrine over Propel. I've been using Propel for a while now and almost every comparison I read states that Propel is not well documented as the first problem and I've read Propel's docs and they're quite well. Also, most of comparisons are dated, (using Propel 1.5+). Does anyone knows of a highly convincing post in a blog where I can see test results and some actual differences? 回答1: I

Something like that? $fields = array('IFNULL(s2.id,s1.id) AS effectiveID','IFNULL(s2.status, s1

问题 I have a Doctrine filter in Symfony2 project. I am trying to set filter's parameter to some value (taken from session) on every request.

问题 I have an existing, non-framework-based PHP/MySQL website. It has a simple security model, with a users table with usernames and hashed (MD5) passwords. I'm currently working on "version 2" of this site, this time using Symfony, with Doctrine. The new version is working fine, and I'm using the sfDoctrineGuard plugin for my user management. I'd like to migrate my existing users into the new app with the minimum of fuss, retaining their existing usernames and passwords. My main problem, though,
