Developing in PHP and, I would love to do everything in PHP only on dynamic programming issues, but I know that to do everything I need web-facing would be impossible without a client-side language.
My goal with the dynamic programming language is only for web-based systems, so PHP always becomes the main language of my projects with approximately 80% of the scope.
Is there anything that can make PHP a client-side language, some library, or something? If not, is there any possibility of this happening or a server-side server-side language?
Note: This question is about innovations that I did not expect in the HTML language, for example, I understand that HTML is a static language, but HTML5 now performs dynamic client-side checks on inputs. CSS is a static language for styles, today CSS3 uses dynamic (client-side) conditions for a given class to be loaded.
If I've been wrong, please correct me.
