PHP - output buffering with global variables in included file

Question

I am trying to include a file using output buffering as follows. But cannot use global variables inside function of an included files.

Main.php

function get_include_contents($filename) {
    if (is_file($filename)) {
        ob_start();
        require $filename;
        return ob_get_clean();
    }
    return false;
}

test.php - included file:

include_once 'settings.php';  // defines many global variables like $obj1, $ojb2

// some processing
test();
// some processing

function test() {
    global $obj1, $obj2;

    // using $obj1
    $obj1->function_obj1();  // $obj1 is not defined
}

Answer 1

First make a class and then create functions in it. For example let your file name be main.php. Then make this

class main 
{
function __construct(){
 // define a constructor 
}
function xyz($a1, $a2 ....$an){
// perform operations 
} 
}

Now make another file make another class. Let's say your file name is main2.php

require_once 'main.php';
class main2{

private $a1;

function __construct()
{
     $this->a1 = new main();
}

function abc()
{
 $fun = $this->a1->xyz($a1, $a2 ....$an);
// and now perform operations 
}
}

After the class ends, you can call the functions with the same concept used in the constructor right after the class ends.
