In this blog post, we will explain how to install PHP 8.3 on AlmaLinux 10 OS. PHP is an open-source scripting language widely used designed mostly for web development. PHP is a versatile language that can be used for different tasks, such as creating dynamic web pages and applications, managing sessions, and interacting with databases. The PHP code is executed on the server, is typically embedded within the HTML, and PHP enables websites to display different content based on the user’s input. The most common usage of PHP is building CMS websites like WordPress, e-commerce platforms like Magento, and social networks like Facebook. The PHP language has a very large community of developers providing support at any time. In the following headings, we will explain different ways of installing PHP8.3.
Installing PHP8.3 on AlmaLinux 10 is a straightforward process that may take a couple of minutes or slightly longer, depending on the installation method. Let’ get started!
Prerequisites
- A server running AlmaLinux 10 OS
- User privileges: root or non-root user with sudo privileges
Update the System
Before we start with the installation of PHP, we will update the system packages to their latest versions. Execute the following command:
sudo dnf update -y && sudo dnf upgrade -y
Install PHP via the default Repository
The good thing about AlmaLinux 10 and PHP 8.3 is that PHP 8.3 is included and enabled in the AlmaLinux 10 OS by default. So installing via this repo is a straightforward process by executing the following command:
sudo dnf install php -y
Once installed, to verify the version, execute the command below:
php -v
You should receive output similar to this:
[[email protected] ~]# php -v
PHP 8.3.19 (cli) (built: Mar 12 2025 13:10:27) (NTS gcc x86_64)

sudo dnf install php-cli php-fpm php-curl php-mysqlnd php-gd php-readline php-mbstring php-apcu php-xml php-dom php-opcache php-zip php-intl php-common php-bcmath php-json -y
To check the installed PHP extension, you can use the command below:

This was installing PHP 8.3 via the default repo. Let’s proceed to the next heading, where we will explain how to install it from source.
Installing PHP8.3 from Source
The installation of PHP8.3 on AlmaLinux 10 from source requires several steps, such as installing prerequisites, downloading the PHP8.3 version, configuring, compiling, and lastly installing. We will go through these steps in this heading. Let’s get things done!
First, enable the power tools repo, necessary for the PHP prerequisites.
sudo dnf config-manager --set-enabled crb
To install the required prerequisites, execute the command below:
sudo dnf install -y wget tar gcc gcc-c++ make autoconf libxml2-devel sqlite-devel curl-devel openssl-devel bzip2-devel libjpeg-turbo-devel libpng-devel freetype-devel libwebp-devel libxslt-devel libicu-devel systemd-devel oniguruma-devel
Once the prerequisites are installed, the next step is to download the exact PHP 8.3 version. In the previous heading, we installed PHP 8.3.19 via the default repo, and now let’s download it so we can install from source:
cd /opt
wget https://www.php.net/distributions/php-8.3.19.tar.gz
tar -xzf php-8.3.19.tar.gz
cd php-8.3.19
Next is to configure the PHP with the PHP extensions:
./configure --prefix=/usr/local/php8.3 \
--with-config-file-path=/usr/local/php8.3/etc \
--with-config-file-scan-dir=/usr/local/php8.3/etc/php.d \
--enable-mbstring \
--enable-mysqlnd \
--with-curl \
--with-openssl \
--with-zlib \
--with-webp \
--enable-fpm \
--with-fpm-user=nginx \
--with-fpm-group=nginx
Once, compile the PHP with the following command:
make -j$(nproc)
You should allow some time for the compilation process to finish. It took 10 minutes to compile it. Once the compilation is done, we can install PHP 8.3 with the command below:
sudo make install
After the installation, we can check the installed version with the following command:
/usr/local/php8.3/bin/php -v You should get the following output:
[root@localhost php-8.3.19]# /usr/local/php8.3/bin/php -v PHP 8.3.19 (cli) (built: Aug 14 2025 17:36:26) (NTS) Copyright (c) The PHP Group Zend Engine v4.3.19, Copyright (c) Zend Technologies To make a shortcut of this command, we can simply make a symbolic link:
ln -s /usr/local/php8.3/bin/php /usr/bin/php
Now you can check the installed version with the same command as in the previous heading:
[[email protected] php-8.3.19]# php -v
PHP 8.3.19 (cli) (built: Aug 14 2025 17:36:26) (NTS)
