Hello All, What is the best method to build and deploy php scripts along the different environments? You can talk about rpm's and stuff My specific scenario is Step1: Developer checks code in to perforce (repo) Step 2: Then I need to upgrade my integration instance. Step 3: Upgrade QA instance Step 4: Upgrade staging Server Step 5: Upgrade production machines What would be the specific build mechanism that I can use for such kind of environments? I also have db scripts that might alter schema. Please provide me samples of any scripts that you might have written to achieve this kid of structure. Any suggestions or scripts will be highly appreciated.
