PHP 8.2 is pretty good, but it feels like it's just patching up old problems rather than building a modern framework.  I\u2019m betting a lot of the \"PHP in 2026\" arguments are just people clinging to the past.  Maybe Symfony will finally pull it into the 21st century.\n\n**Comment 2:**\n\n> I think the biggest thing holding PHP back is the ecosystem.  It\u2019s fragmented and there\u2019s no *one* clear path for building anything substantial.  You\u2019re bouncing between Laravel, Symfony, CodeIgniter, and a dozen other micro"
