Fatal error: Class \'DOMDocument\' not fo

Answer 1

Using Suse Linux (Linux linux 3.16.7-48-default) and PHP 5.6.1 as root, this helped:

zypper in php5-dom

plus restart

systemctl restart apache2

Answer 2

Package php-dom is a virtual package provided by:
  php7.1-xml 7.1.3+-3+deb.sury.org~xenial+1
  php7.0-xml 7.0.17-3+deb.sury.org~xenial+1
  php5.6-xml 5.6.30-9+deb.sury.org~xenial+1
You should explicitly select one to install.

In case anyone using 5.6 versions then go with this way

sudo apt-get install php5.6-xml

For Php Ver PHP7, Ubuntu:

sudo apt-get install php7.1-xml

or by

yum install php-xml

Answer 3

For Centos 7 and php 7.1:
yum install php71w-xml
apachectl restart

Answer 4

I'm using CentOS 7 with virtualmin and three PHP versions. I also have REMI repo enabled. it worked for me:

Step 1:

Just append PHP major version number like this php{version number}-xml. And run yum install

yum install php70-php-xml
yum install php71-php-xml
yum install php72-php-xml

Step 2:

Don't forget to restart Apache:

service httpd restart

Answer 5

You need to install the DOM extension. You can do so on Debian / Ubuntu using:

sudo apt-get install php-dom

And on Centos / Fedora / Red Hat:

yum install php-xml

If you get conflicts between PHP packages, you could try to see if the specific PHP version package exists instead: e.g. php53-xml if your system runs PHP5.3.

Answer 6

If you are using PHP7.0 to install Magento, I suggest to install all extensions by this command

sudo apt-get install php7.0 php7.0-xml php7.0-mcrypt php7.0-curl php7.0-cli php7.0-mysql php7.0-gd libapache2-mod-php7.0 php7.0-intl php7.0-soap php7.0-zip php7.0-bcmath

I need to Google some times to meet Magento requirement.

I think you can replace the PHP version to 7.x if you use another PHP version

And restart Apache is needed to load new extensions

sudo service apache2 restart
