Function name must be a string php?

After few hours of googling and searching for answer, i gave up and got very frustrated with php, no support out there on basic errors. Anyway, here is my function, what am I doing wrong?

$accessToken = function(){
        $array = array(
            "foo" => "bar",
            "bar" => "foo"
        );
        
        $obj = json_encode($array);
        $obj = json_decode($obj);
        
        return $obj->foo;
};

$getInfo = function(){
       
        $code = $accessToken();
        return $code;

        
};

$getInfo();

I get error

Notice: Undefined variable: accessToken in C:\inetpub\wwwroot\mysite\lab\cfhttp.php on line 43

Fatal error: Function name must be a string in C:\inetpub\wwwroot\mysite\lab\cfhttp.php on line 43

In PHP you usually define a function in another fashion. Try the following:

function accessToken() {
     $array = array(
          "foo" => "bar",
          "bar" => "foo"
     );

     $obj = json_encode($array);
     $obj = json_decode($obj);

     return $obj->foo;
}

function getInfo() {
     $code = accessToken();
     return $code;
}

getInfo();

You can also take a look here http://php.net/manual/en/functions.variable-functions.php and http://php.net/manual/en/functions.user-defined.php

$accessToken isnt in scope inside $getInfo()

$accessToken = function(){
        $array = array(
            "foo" => "bar",
            "bar" => "foo"
        );

        $obj = json_encode($array);
        $obj = json_decode($obj);

        return $obj->foo;
};

$getInfo = function($accessTokenFunction){

        $code = $accessTokenFunction();
        return $code;


};

$getInfo($accessToken);

use () to take a variable inside this scope

$getInfo = function() use ($accessToken) {
    $code = $accessToken();
    return $code;
};
