I just setup a symfony app my new redundancy server but it show “PHP Fatal error: Call to a member function setData()” in my apache error log. What i did is just restore the source code from my subversion server and it shouldn’t have any problem. I suspect there must be something wrong with the app installed in the server.
After some research, i found out the problem is caused by Doctrine. Doctrine for Symfony 1.4 need minimum PHP 5.2.3 installed. But my server admin accidentally installed PHP 5.1.x on the redundancy server. After he upgrade the PHP to version PHP 5.2.17, everything seems fine.
To upgrade PHP version from 5.1 to 5.2, you can refer to CentOS Wiki
