How to compile PHP
PHP can be compiled by setting up the dependencies, building the configure script (./buildconf), configuring the build ./configure, and running make.
Detailed articles on how to compile PHP are available for Ubuntu/Debian based systems and Fedora/RHEL based systems.

Windows binaries
Non-Thread Safe Builds
Non-Thread Safe (NTS) builds are single-threaded PHP builds. They can be used on web servers that integrate PHP over FastCGI protocol, such as Nginx, Caddy, and IIS.
Thread-Safe Builds
Thread-Safe (TS) builds are multi-thread PHP builds, often used to integrate PHP as a Server API for multithreaded servers. The most common use case is using PHP as an Apache module.

Docker/Podman Containers

PHP CLI
PHP CLI Containers images only include the PHP CLI, and no FPM or Apache modules. The Alpine builds are lightweight, but may introduce incompatibilities due to their musl builds. Albeit their larger size, the Debian-based (without the "-alpine" suffix) images are more complete, and widely used.

Alpine-based: Lightweight, but may introduce incompatibilities due to their musl builds.
docker pull php:7.4.2-cli-alpine

Debian-based: More compatible with other components, complete, and are widely used.
docker pull php:7.4.2-cli
PHP CLI + Web Server Integration
These container images include PHP CLI, and a web server integration. FPM container images can be integrated with web servers such as Nginx, Caddy, and Apache with Event MPM. The Apache container images include Apache web server, integrating PHP as an Apache module.

Alpine-based: Lightweight, but may introduce incompatibilities due to their musl builds.
docker pull php:7.4.2-fpm-alpine

Debian-based ZTS Apache: Includes Apache web server integrating PHP as an Apache module.
docker pull php:7.4.2-apache

Debian-based NTS FPM: PHP-FPM, can be integrated with Nginx, Caddy, and other web servers over Fast CGI.
docker pull php:7.4.2-fpm
