[PHP Modules]

ctype
curl
date
dom
exif

filter
ftp

ico         


        

Answer 1

I'm using ubuntu 18.04. When I checked for SimpleXML in module list, it was stated same like yours.

Then I check my phpinfo() which says it was pulling from different php version and not the same with php cli.

To check php cli version, I run php -v

To check for phpinfo(), I put the function at the top of index.php of my script.

After confirming that my phpcli version is different than whats in phpinfo,

I simply run this 2 command

sudo a2dismod php7.0

sudo a2enmod php7.3

Then restart my apache

sudo systemctl restart apache2

After that, I test again my phpinfo()

Now it is working.

Answer 2

I had the same issue. I fixed it by installing php7.2-xml:

$ sudo apt-get install php7.2-xml
$ sudo systemctl reload apache2 

After that, SimpleXML got listed by php -m:

$ php -m | grep -i simple
SimpleXML
