Is there a way to share object between php pages?

Question

I am new to php, but in other web technologies, you can share objects between page instances. For example, in java jsp pages you easily have on class that exist as static cl

Answer 1

There's a fundamental difference between web-served Java and web-served interpreted languages like PHP and Perl. In Java, your web server will have an operating environment that maintains state (ie. Tomcat). With interpreted languages, a request to your web server will generally spawn a new web server thread, which in turn loads a fresh operating environment for that thread, in this case, the PHP environment.

Therefore, in PHP, there is no concept of page instances. Every request to the web server is a fresh start. All the classes are re-loaded, so there is no concept of class sharing, nor is there a concept of resource pooling, unless it is implemented externally.

Sharing sockets between web requests therefore isn't really possible.
