Php passing the same objects on another file

Question

1) Suppose I have 2 php files: fileA.php, and fileB.php And I have 1 class file: myClassFile.php

in fileA.php, I need to instantiate a MyClass class in myClassFile.php:

...
myObject = new MyClass();
...

in fileB.php, I need to use the myObject object created in fileA.php.

How would I do that? Is using sessions the way to go?

$_SESSION["my_object"] = myObject;

or are there better ways? Specifically, how will it be implemented?

2) Suppose I don't use solutions similar to the above.. Will myObject in fileA.php be lost (destroyed, or freed) when the user proceeds to fileB.php? That is, will there be no more reference to myObject in fileB.php?

its my understanding that if the user leaves fileA, myObject will be lost unless you store it somewhere (session, log file, or anywhere else). now about the first question, why would you wanna do that? and why dont you create a common php file, where you can call the class and it will be available on every page. — Ahoura Ghotbi

just create a new file, call it common.php, include it on top of all your current php files (or the ones you need the class to be available on) and inside the common.php file, include the class, instantiate it and then you can access it from all the files. — Ahoura Ghotbi

oh I also forgot, as @randomwhitetrash mentioned you can use singleton, or you can change your class get and set method to store stuff in a database or a file. — Ahoura Ghotbi

It sounds like you're doing something unnecessary complicated.

The information you passed and treated in MyClass has to be available somehow in the object.

Create a method to extract all these information to an array and save this array in a session. When reaching the next page, create an instance of MyClass again and feed the object in another method for this purpose with the information array from your session.

I am not an expert but if your object is like a configuration object which you need to access from many places then consider using Singleton pattern
