According to PHP documentation, if you want to add something to php, you need to rerun configure, make and make install. In my case, I see no errors while doing this, but changes are not shown with phpinfo(). The only way to actually change something is to remove php with make distclean and install anew with all the configure options. Any ideas?
Apache is 2.2. Ubuntu 9.04 PHP 5.3.1
Apache compiled from source and so is PHP.
