This Week In PHP Internals | July 15, 2026

Short summary

This week in PHP Internals covers three major threads: Holly Schilling's Swift/C#-style class extension proposals (3 draft RFCs with working prototypes), Gina P. Banyard's PHP 8.6 deprecation bundle reaching frozen status with a vote scheduled for July 27, and Paul M. Jones's function autoloading RFC (attempt 5) being slimmed down after Tim Düsterhus objected to piggy-backing the strict_namespace directive. The extension proposal sparked the week's biggest thread at 26 messages, with Holly ultimately rewriting all drafts around C# 14's extension syntax.
