PHP Core Roundup #18

Published on by ,

Welcome back to PHP Core Roundup series! This is where we highlight and celebrate the improvements made to PHP during the month past by the PHP development team and members of the PHP Foundation.

The PHP Foundation is a collective of PHP contributors, veterans, and companies that collaborate to ensure the long-term sustainability of the PHP programming language. The foundation currently supports six contributors focused on PHP's maintenance, debt reduction, and feature development. These contributors work closely with others on coding, documentation, and discussions.

Started over a year ago, the PHP Core Roundup series offers a summary of the latest developments, discussions, and news about PHP Core, contributed by both PHP Foundation members and other participants. This post is the thirteenth in the PHP Core Roundup series.

The PHP development team released two new versions in October 2023:

PHP 8.2.12 and PHP 8.1.25

These releases include several bug fixes and improvements, notably in areas such as Core, CLI, CType, DOM, Fileinfo, Filter, Hash, Intl, MySQLnd, Opcache, PCRE, SimpleXML, Streams, XML, and XSL.

Recent RFCs and Mailing List Discussions

Changes and improvements to PHP are discussed, reported, and voted on by the PHP Foundation Team, the PHP development team, and contributors. Bug reports are made to the PHP issue tracker, changes are discussed in mailing lists, minor code changes are proposed as pull requests, and major changes are discussed in detail and voted on as PHP RFCs. Documentation and the website changes are also discussed and improved at their relevant Git repositories on GitHub.

Hundreds of awesome PHP contributors put their efforts into improvements to the PHP code base, documentation, and the website. Here is a summary of some changes made by the people behind PHP. Things marked with 💜 are done by the PHP Foundation team.

PHP 8.3 GA to be released this month!

PHP 8.3.0 GA is scheduled to be released on November 23rd. PHP 8.3.0 RC5 is already released, and RC6 (the last one) is scheduled for November, 9.

PHP 8.3.0 RC versions are available in Remi’s repos for Fedora/RHEL, Ondrej's repos for Debian/Ubuntu LTS, Docker images on Docker Hub, and compiled Windows binaries on

PHP 8.0 will reach EOL

PHP 8.0 will reach its End of Life (EOL) and will no longer receive security updates after November 26, 2023. You can always check the release and support schedule at

RFC Updates

Following are the RFCs and major pull-requests discussed, voted, and implemented since our last update.

In Voting: Straw poll - How to name the Process resource after it is converted to an object by Máté Kocsis 💜

As part of PHP's efforts in gradually phrasing out resource objects (php-tasks#6, article on PHP.Watch), this RFC polls the proposed names for the resource object class name that replaces Process resources. This ranked-choice poll (following STV) intends to pick a name from \Process, \ProcessHandle, and \OS\Process.

Implemented: Increasing the default BCrypt cost by Tim Düsterhus

RFC was approved unanimously, but in the second vote, where a new cost value had to be determined, opinions were divided.

The cost will be increased to 12 in PHP 8.4.

Implemented: XML_OPTION_PARSE_HUGE by Niels Dossche

A new option will be added to the event-driven (SAX) XmlParser that would allow it to parse large documents.

Accepted: DOM HTML5 parsing and serialization by Niels Dossche

PHP 8.4 will get new classes: DOM\HTMLDocument and DOM\XMLDocument to the dom extension. Existing dom classes in the global namespace get an alias in the new DOM namespace.

The HTMLDocument class will add support for HTML5 document parsing and serializing. The XMLDocument class serves as a modern alternative to \DOMDocument, which is retained for compatibility. These new classes also provide a more misuse-resistant API for loading documents.

Accepted: A new JIT implementation based on IR Framework by Dmitry Stogov

RFC proposed a new JIT implementation based on a separately developed IR Framework. The main advantage of the new approach is that PHP source code will be freed from the low-level details of JIT compilation. The downside is a longer JIT-compilation time.

The proposal was accepted, so Dmitry Stogov merged the new JIT into the master which means it will be available in PHP 8.4.

Under discussion: RFC1867 for non-POST HTTP verbs by Ilija Tovilo 💜

Now PHP supports the parsing of multipart/form-data content type natively, but only for POST requests. If POST request has the multipart/form-data content type, the request body is immediately consumed before starting the PHP script and populated into the $_POST and $_FILES superglobals.

RFC proposes to add a new function request_parse_body() to expose the existing functionality to userland so that it may be used for other HTTP verbs.

Under discussion: Rounding Integers as int by Marc Bennewitz

Currently round(), ceil() and floor() functions return float numbers, but when using integers above 2^53 you get unexpected results due to loss of precision.

RFC proposes to perform rounding for a given integer and returning the resulting integer if possible.

Under discussion: Unbundle ext/imap, ext/pspell, ext/oci8, and ext/PDO_OCI by Derick Rethans 💜

RFC proposes to unbundle these extensions: remove them from the PHP source distribution, and move them to PECL.

Under discussion: Multibyte for trim function mb_trim, mb_ltrim and mb_rtrim by Yuya Hamada

RFC proposes to add multibyte support for trim functions.

Under discussion: Change the edge case of round() by Saki Takamachi

RFC proposes to change the round() behavior, and stop expecting decimal behavior to float point and start expecting floating point to behave as floating point.


While PHP 8.3 is just around the corner, the documentation available on, requires updating.

Gina P. Banyard 💜 is tracking the progress for PHP 8.3 related changes in php/doc-en#2796, and also triaged issues in the docs and marked several of them as "good first time", which are ideal easy picks if you would like to start contributing to PHP docs. You can find the full list on GitHub.

Merged PRs and Commits

Following are some changes that did not go through an RFC process because they are either planned, bug fixes, or progressive enhancements.
