Summary: 

The current SVM on-premise version doesn't support the PHP 7.3, since PHP 7.2 has already been EOL in November 2020. This article will help our SVM on-premise customer to upgrade the PHP 7.2 version to PHP 7.3.

Steps : 

• Prerequisite: you need to have PHP 7.2 installed
• 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

yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -y install epel-release yum-utils

• Disable repo for PHP 7.2

yum-config-manager --disable remi-php72

• Enable repo for PHP 7.3

yum-config-manager --enable  remi-php73

• Unzip the attached ioncube_loader_lin_7.3 zip file and use winscp to place at the following location /usr/local/Secunia/csi/lib
• yum update (Make sure you install the php 7.3)
• php –version (Make sure you have php 7.3 installed)
• nano /etc/php.d/00-ioncube.ini
• Edit 00-ioncube.ini ( Change the zend_extension=/usr/local/Secunia/csi/lib/ioncube_loader_lin_7.2.so to ioncube_loader_lin_7.3.so)
• apachectl restart
