"I have a system ubuntu 12.04, and I install the php v5.5.27 from the sources (also apache2 from sources) and I test it there with no problem. Then I installed php 5.5.9 (the version with the problem in ubuntu) and it works."
Does PHP 5.5.9 work or not work? Or do you mean the built-from-source version worked but the Ubuntu one does not? Would it be possible to re-test with the latest php5 (5.5.9+dfsg-1ubuntu4.14) from trusty-updates?
@armand1, to clarify:
