Function call undefined Doctrine \ ORM \ Mapping \ Driver \ simplexml_load_file ()

Question

I am using Symfony2 and I am deploying my network to a CentOs6 server. I got this exception

FatalErrorException: Error: Call to undefined function Doctrine\ORM\Mapping\Driver\simplexml_load_file() in vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/Driver/XmlDriver.php line 736 

What did I miss? Thanks

Answer 1

it looks like for some reason you don't have the simplexml extension installed in your php version.

Look here for full details.
