Fix php unit test

Now test are working, some failure exist but I think some are comming from the outputter systems and some other from upgrade of libs.

Tests: 169, Assertions: 605, Failures: 16.

For information, I have the following configuration : 

ubuntu (64 bits) 12.10(quantal)

PHP 5.4.6-1ubuntu1

pear list -a
