Question

I am trying to learn oop in php, but the below code is not working could someone provide an alternate answer?

<?php
    class abc {
        public $a = 1;
        $b = $a;

        function foo(){
            //some function..
        }

    }
?>

I want to assign value of variable “a” to variable “b”.

Answer 1

You can assign the value of $a to $b like so: $this->b = $this->a within the __construct method which gets called upon object creation, assuming you’re running PHP 5.
