sudo yum --enablerepo=ius install php56u*

Check to make sure it’s been installed/updated:
rpm -qa | grep -i php
If you’ve already had php installed previously (i.e. you used the update method above) then run this command:
If not then simply restart httpd:
sudo service httpd restart
Troubleshooting / How To Test
Explanation troubleshooting basics and expectations.
- create and save a file called phpinfo.php in your httpd Documentroot with only this in it:
- Let’s go test and make sure we can see the current php version and other information:
- Make sure httpd is started, also make sure you have correctly replaced the php.ini file if you had previously installed php from official Centos repos.
1 | <?php phpinfo(); ?> |
Open a web browser and navigate to: http://www.example.com/phpinfo.php
sudo service httpd status
