Access array inside a php function

Question

Access array with same name $userinfo inside a php function

<?php 
    $userinfo['name'] = "bob";
    $userinfo['lastname'] = "johnson";

    function displayinfo() {
//not working 
    echo $userinfo['name']
//global also not working 
    echo global $userinfo['lastname'];

    }
    displayinfo();

?>

how to acess the arrays in the $userinfo var since it has more than one array in the same variable name?

echo $userinfo['name']
//global also not working 
echo global $userinfo['lastname'];

both do not working.

Better to pass the array into the function as global is generally discouraged — Nigel Ren

I recommend passing the variable to the function:

function displayinfo($userinfo) {
  echo $userinfo['name'];
}

$userinfo['name'] = "bob";
$userinfo['lastname'] = "johnson";

displayinfo($userinfo);

See:
PHP global in functions
Are global variables in PHP considered bad practice? If so, why?

Ok why it's better than use global?

There are several potential reasons listed here. You can use global, but things might get messy depending on your context.

  global $userinfo;
  echo $userinfo['lastname'];
}
