Codeigniter access variable data which is defined on function1 on function2

Question

I have two functions in a class. What i need is something like this (This is incorrect)

class Home{

    function one(){
        $var1 = "abc";
    }

    function two(){
        $var2 = $var1;
        echo $var2; //This needs to output 'abc' for me.
    }
}

Unfortunately, it is not working. Can somebody help me please.

Does this answer your question?

Yes I understand the scopes, but is there a anyway i can access that variable defined in another function? — shashi kumar, May 26 '20 at 05:37
I would suggest you also read up on [class properties](https://www.php.net/manual/en/language.oop5.properties.php) — M. Eriksson, May 26 '20 at 06:00

There are many ways to achieve this, one of the ways is mentioned below, if you're learning OOP then I'd suggest watching mmtuts videos which are quite informative.

<?php 

class Home{

    public $var1 = 'xyz';

    function one($x){ // or public function ... 

        $this->var1 = $x;
    }

    function two(){ // or public function ...

        $var2 = $this->var1;
        echo "var2: {$var2}"; //This needs to output 'abc' for me.
    }

}

$xyz = new Home(); // instantiate the class
$xyz->one('abc'); // call the function, pass the variable 
$xyz->two();    // get the value
