How to uninstall an older PHP version from centOS7

Question

My project is on Laravel 5.2. and as per guide it required php >= 5.5.6 but there was php 5.4 intalled and I had to upgrade php version through YUM, But now it is giving error "PDO driver not found" and I tried YUM install php-pdo but it's giving error that "there is conflict between php56w-common and php-comon-5.4.16". I am stuck on this point

Solution

Subscribing to the IUS Community Project Repository

cd ~
curl 'https://setup.ius.io/' -o setup-ius.sh

Run the script:

sudo bash setup-ius.sh

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd
