AWS Amazon Linux Upgrade PHP 72 to 74

Here are the simple steps to follow in order to upgrade php7.2, which has reached EOL, but there are many installations still using this version.

At the time of writing, php7.4 is getting only security support and will reach EOL on 2022-11-28. Consider switching to a 8.x version, if that's possible.

Step 1. System Updates

It's important to have an up to date system. If you are keeping it updated on a regular basis, you may skip this step.

sudo yum update

Step 2. Disable the old topic in extrase

First, let's check the php version and modules installed

php -v

PHP 7.2.34 (cli) (built: Oct 21 2020 18:03:20) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

Now, disable the topics

sudo amazon-linux-extras disable php7.2

sudo amazon-linux-extras disable lamp-mariadb10.2-php7.2

Step 3. Enable the new topic and upgrade

sudo amazon-linux-extras enable php7.4

Here is a line stripped output, but you can see the confirmation the new version is enabled and suggested commands to run in order to upgrade at the bottom

  0  ansible2                 available    \
        [ =2.4.2  =2.4.6  =2.8  =stable ]
...
 42  php7.4=latest            enabled      [ =stable ]
...
 61  dnsmasq2.85              available    [ =stable ]

Now you can install:
 # yum clean metadata
 # yum install php-cli php-pdo php-fpm php-json php-mysqlnd

Note, the yum install command above, apparently doesn't include all the packages you might have, so double check by running this:

rpm -qa | grep php

php-mbstring-7.2.34-1.amzn2.x86_64

php-fpm-7.2.34-1.amzn2.x86_64

rpm -qa --qf "sudo yum install %{NAME}\n" | grep php sudo yum install php-mysqlnd sudo yum install php-mbstring sudo yum install php-pecl-mcrypt sudo yum install php-common sudo yum install php-bcmath sudo yum install php-gd sudo yum install php-xml sudo yum install php-pecl-imagick sudo yum install php-pdo sudo yum install php-cli sudo yum install php-json sudo yum install php-fpm sudo yum install php-soap
