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:8.3.8-cli-alpine

Debian-based: More compatible with other components, complete, and are widely used.
docker pull php:8.3.8-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:8.3.8-fpm-alpine

Debian-based ZTS Apache: Includes Apache web server integrating PHP as an Apache module.
docker pull php:8.3.8-apache

Debian-based NTS FPM: PHP-FPM, can be integrated with Nginx, Caddy, and other web servers over Fast CGI.
docker pull php:8.3.8-fpm

ChangeLog

CGI

CLI

  • Fixed bug GH-14189 (PHP Interactive shell input state incorrectly handles quoted heredoc literals.).

Core

  • Fixed bug GH-13970 (Incorrect validation of #[Attribute] flags type for non-compile-time expressions).

DOM

  • Fix crashes when entity declaration is removed while still having entity references.
  • Fix references not handled correctly in C14N.
  • Fix crash when calling childNodes next() when iterator is exhausted.
  • Fix crash in ParentNode::append() when dealing with a fragment containing text nodes.

Filter

FPM

  • Fix bug GH-14175 (Show decimal number instead of scientific notation in systemd status).

Hash

  • ext/hash: Swap the checking order of __has_builtin and __GNUC__

Intl

  • Fixed build regression on systems without C++17 compilers.

MySQLnd

  • Fix bug GH-14255 (mysqli_fetch_assoc reports error from nested query).

Opcache

  • Fixed bug GH-14109 (Fix accidental persisting of internal class constant in shm).

OpenSSL

  • The openssl_private_decrypt function in PHP, when using PKCS1 padding (OPENSSL_PKCS1_PADDING, which is the default), is vulnerable to the Marvin Attack unless it is used with an OpenSSL version that includes the changes from this pull request: https://github.com/openssl/openssl/pull/13817 (rsa_pkcs1_implicit_rejection). These changes are part of OpenSSL 3.2 and have also been backported to stable versions of various Linux distributions, as well as to the PHP builds provided for Windows since the previous release. All distributors and builders should ensure that this version is used to prevent PHP from being vulnerable.

Standard

XML

  • Fixed bug GH-14124 (Segmentation fault with XML extension under certain memory limit).

XMLReader

  • Fixed bug GH-14183 (XMLReader::open() can't be overridden).
