Step 1: Add PHP 7.3 Remi repository
PHP 7.3 is available for CentOS 7 and Fedora distributions from the Remi repository. Add it to your system by running
sudo yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm sudo yum -y install epel-release yum-utils
Step 2: Disable repo for PHP 5.4
By default, the enabled repository is for PHP 5.4. Disable this repo and enable on for PHP 7.3
sudo yum-config-manager --disable remi-php54 sudo yum-config-manager --enable remi-php73
Step 3: Install PHP 7.3 on CentOS 7 / Fedora
Once the repo has been enabled, install php 7.3 on CentOS 7 or Fedora using the command
p-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json
$ php -v PHP 7.3.1 (cli) (built: Jan 8 2019 13:55:51) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.1, Copyright (c) 1998-2018 Zend Technologies
Step 4: Installing other PHP 7.3 Extensions
Install PHP 7.3 extensions by using the syntax
sudo yum install php-<entension-name>
As an example, to install a mysql module for PHP applications that use MySQL databases, you’ll run:
sudo yum install php-mysql
This will only work if the default repository for PHP packages is 7.3
sudo yum install php-mysqlnd
Confirm:
