Solution for upgrade to ownCloud 10.0.0.7 and missing php intl module

Solution_for_upgrade_to_ownCloud_10.0.0.7_and_missing_php_intl_module.txt

I have ownCloud running on a Cent OS7 machine.  Somehow, I am using php 5.6.18 instead of php 7.0 or later.
I got the php 5.6.18 from some awkward repos other people maintain (probably not a good idea, I should change this).

When I did a yum update, a new version of ownCloud got installed.  When I opened my ownCloud home page I got greeted
not with the normal login page for ownCloud.  Instead of a userid/password prompt, I got two messages about not
being able to load php module (I knew I should have saved the exact error messages).

After bit of Googling, I found a solution.

  sudo su

  cd /var/www/html
  
  # Create this file
  cat phpver.php
  <?php
    phpinfo();
  ?>

  chown root.apache phpver.php
  chmod 755 phpver.php
  
  # Open this url:  https://<owncloud_host>/phpver.php
  # You can see the php version (see CORE section) and search for intl, it is not there.

  yum install rh-php56-php-intl.x86_64

  rpm -ql rh-php56-php-intl-5.6.25-1.el7.x86_64
  /etc/opt/rh/rh-php56/php.d/20-intl.ini
  /opt/rh/rh-php56/register.content/etc/opt/rh/rh-php56/php.d/20-intl.ini
  /opt/rh/rh-php56/root/usr/lib64/php/modules/intl.so

  cd /usr/lib64/php/modules/
  ln -s /opt/rh/rh-php56/root/usr/lib64/php/modules/intl.so .

  systemctl restart httpd

I am glad I am persistent.
