php Trying to migrate a symfony system to a new server. It show me “PHP Fatal error: Class ‘DOMDocument’ not found in…” when i click on some link. After some checking, the problem actually caused by a missing module – php xml module. Install the module will solve the problem 🙂

You must ssh to your system using root
Now install the xml module in php using yum (yum is only available in selected linux distribution eg: CentOS, RedHat, Fedora, etc)
```
yum install php-xml
```
just press ‘Y’ to install the dependencies module.
Once the installation finish, you need to restart your apache and the error message “Class ‘DOMDocument’ not found” will go away!
```
service httpd restart
