PHP 7 simpleXML

Question

I\'m testing PHP7, and have a weird issue after a recent update. SimpleXML should be enabled by default, and my phpinfo page shows that it is available:

Answer 1

------------------in centos-------------------------

find out which package provides php-xml:

 yum provides php-xml

then from the output list,select the appropriate one, install

yum install php70u-xml-7.0.14-2.ius.centos7.x86_64

Answer 2

Because Google led me here, on Ubuntu 20.04 this works in 2020:

sudo apt install php7.4-xml

If on Apache2, remember to restart (probably not necessary):

sudo systemctl restart apache2

Answer 3

I'm using Bash on Windows (Ubuntu 16.04) and I just installed with php7.0-xml and all is working now for the Symfony 3.2.7 PHP requirements.

sudo apt-get install php7.0-xml
