PHP 8.5.6 update fixes multiple issues including critical glitches and enhances performance.
PHP version 8.5.6 (07 May 2026) Core: Fixed bug GH-19983 (GC assertion failure with fibers, generators and destructors)

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.
