Dist Fedora Esm H88
Recent fixes in PHP 8.4.16 address critical issues, enhancing security in Fedora 42 with several bug corrections and updates.
PHP version 8.4.16 (18 Dec 2025) Core: Sync all boost.context files with release 1.86.0

Summary

PHP is an HTML-embedded scripting language. PHP attempts to make it

easy for developers to write dynamically generated web pages. PHP also

offers built-in database integration for several commercial and

non-commercial database management systems, so writing a

database-enabled webpage with PHP is fairly simple. The most common

use of PHP coding is probably as a replacement for CGI scripts.
