Description:
------------
When building PHP with shared extensions (common case when packaging it for Linux distributions) several extensions depend on one another and the load order is important in the ini configuration (extension=name.so). If for example the wddx.so extension is loaded before the xml.so, PHP emits some warnings...


This is probably happening with several other extensions that depend on one another as well.

Solution might simply involve making a list of shared extensions in a proper order based on their dependencies (PHP_MODULES in Makefile).


Test script:
---------------
./configure --disable-all --enable-wddx=shared --enable-xml=shared --enable-libxml
make
make test

Expected result:
----------------
Tests executed without warnings about missing extensions.

Actual result:
--------------
