I don't know why it unable to load dynamic library '/usr/lib/php5/extensions/dom.so' and '/usr/lib/php5/extensions/gettext.so',I really can find the two files in the derectory of '/usr/lib/php5/'.

I try to get help in google,but google show no result.

and now I  really don't know how to deal with it!!!!!
