For PHP 7 and Ubuntu 14 04 the procedure is follows  Since PHP 7 is not in the official Ubuntu PPAs you likely installed it through Ondrej Sur   s PPA  sudo add-apt-repository ppa ondrej php   Go to  etc php 7 0 fpm and edit php ini  uncomment to following line   extension php xmlrpc dll   Then simply install php7 0-xml   sudo apt-get install php7 0-xml   And restart PHP   sudo service php7 0-fpm restart   And restart Apache   sudo service apache2 restart   If you are on a later Ubuntu version where PHP 7 is included  the procedure is most likely the same as well  except adding any 3rd party repository

For Nginx  without apache  and PHP 7 2  installing php7 2-xml wasn t enough  Had to install php7 2-simplexml package to get it to work  So the commands for debian ubuntu  update packages and install both packages  apt update apt install php7 2-xml php7 2-simplexml   And restart both Nginx and php  systemctl restart nginx php7 2-fpm

Make sure that you have php-xml module installed and enabled in php ini   You can also change response format to json which is easier to handle  In that case you have to only add  amp format json to url query string    rest url    http   api facebook com restserver php method links getStats amp format json amp urls   urlencode  source url     And then use json decode   to retrieve data in your script    result   json decode  content  true    fb like count    result  like count

I think it can be something like in this Post  Class  SimpleXMLElement  not found on puphpet PHP 5 6 So maybe you could install activate  php-xml or php-simplexml   Do not forget to activate the libraries in the php ini file   like the top comment

If the XML module is not installed  install it   Current version 5 6 on ubuntu 14 04   sudo apt-get install php5 6-xml      And don t forget to run sudo service apache2 restart command after it   Zulhilmi Zainudi
