The original poster described a situation where an application uses component A and component B each of which depend on different versions of component C. Unless I missed a corresponding feature so far, Composer does not solve this problem. This problem could be solved, however, by encoding the version number in the namespace name: namespace vendor\component\v100 { class foo {} } namespace vendor\component\v110 { class foo {} } This would allow the usage of two versions of a component inside the same PHP process. -- Sebastian Bergmann Co-Founder and Principal Consultant http://sebastian-bergmann.de/ http://thePHP.cc/
