Php Solutions
Solution 1 - Php
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.
Solution 2 - Php
PHP 7.0:
- Ubuntu:
apt-get install php7.0-xml - CentOS / Fedora / Red Hat:
yum install php70w-xml
PHP 7.1:
- Ubuntu:
apt-get install php7.1-xml - CentOS / Fedora / Red Hat:
yum install php71w-xml
PHP 7.2:
- Ubuntu:
apt-get install php7.2-xml - CentOS / Fedora / Red Hat:
yum install php72w-xml
PHP 7.3:
- Ubuntu:
apt-get install php7.3-xml - CentOS / Fedora / Red Hat:
yum install php73w-xml
PHP 7.4:
- Ubuntu:
apt-get install php7.4-xml - CentOS / Fedora / Red Hat:
yum install php74w-xml
PHP 8.0
- Ubuntu:
apt-get install php8.0-xml - CentOS 8 [with
php:remi-8.0enabled]:dnf install php-xml
Solution 3 - Php
PHP8: (latest version)
sudo apt-get install php8.0-xml
PHP7:
sudo apt-get install php7.1-xml
You can also do:
sudo apt-get install php-dom
and apt-get will show you where it is.
Solution 4 - Php
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
Solution 5 - Php
I'm using Centos and the followings worked for me , I run this command
yum --enablerepo remi install php-xml
And restarted the Apache with this command
sudo service httpd restart
Solution 6 - Php
Create an empty PHP file and put only <?php phpinfo(); in it, look at it in a browser.
Check if you can spot --disable-dom in the configuration options and/or if you can see details about the DOM extension in the list below.
If you cannot see DOM in the list or you see it is disabled, your PHP installation does not include the DOM extension. You'll need to recompile your PHP installation from source to remedy that.

After a long time suffering from it in PHPunit...
For those using namespace, which is very common with Frameworks or CMS, a good check in addition to seeing if php-xml is installed and active, is to remember to declare the DOMDocument after the namespace:
namespace YourNameSpace\YourNameSpace;
use DOMDocument; //<--- here, check this!
Solution 8 - Php
In my case the problem was it was the use of namespace at the top of php file, exemple :
namespace MediaWiki\Extensions\ParserFunctions;
To solve this problem add the following line:
use DOMDocument;
So no need of installing dom or xml if they are already installed. It is a php language trap.
Solution 9 - Php
This help for me (Ubuntu Linux) PHP 5.6.3
> sudo apt-get install php5.6-dom
Thats work for me.
Solution 10 - Php
For PHP 7.4 Install the DOM extension.
Debian / Ubuntu:
sudo apt-get update
sudo apt-get install php7.4-xml
sudo service apache2 restart
Centos / Fedora / Red Hat:
yum update
yum install php74w-xml
systemctl restart httpd
For previous PHP releases, replace with your version.
Solution 11 - Php
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
Solution 12 - Php
On fedora 26:
dnf install php-dom
Fixes it !
Solution 13 - Php
For Centos 7 and php 7.1:
yum install php71w-xml
apachectl restart
Solution 14 - Php
If compiling from source with --disable-all then DOMDocument support can be enabled with
--enable-dom
Example:
./configure --disable-all --enable-dom
Tested and working for Centos7 and PHP7
Solution 15 - Php
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
Solution 16 - Php
On a Amazon Linux 2 with PHP 8.0, I had to
yum-config-manager --enable remi-php80
yum install php-xml
Do not forget to restart PHP
systemctl restart php-fpm
Solution 17 - Php
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
Solution 18 - Php
PHP 7.X Centos 7
I got dependency issues when trying to install module with above suggestions, adding this flag:
--enablerepo=remi-php7X
Resolved dependencies.
So
sudo yum --enablerepo=remi-php7X install php-xml
Then
service httpd restart
