How to create a single function with different criteria on WordPress?

I’m newbie in PHP, so be kind please! And I’m sorry if it’s too repeated, but my brain is burning. I want to learn how to change the variables using only one function of WordPress.

This is my variables…

function be_comu() {
$name = 'BE';
echo $name;
}

function cn_comu() {
$name = 'CN';
echo $name;
}

function mn_comu() {
$name = 'MN';
echo $name;
}

This is my function and be_comu() is a variable that I want to change. 

function turismo() {
ob_start();
be_comu();
$rota = ob_get_clean();

echo $rota;
}

How to change the result to cn_comu or mn_comu without creating a new function?

  1. With call_user_func (PHP is awesome that way):

    function turismo($func_name) {
    // First, let's be sure the function actually exists to prevent fatal errors
    if ( ! function_exists($func_name) ) {
        echo "Whoah! Can't call a function that doesn't exist!";
        return;
    }

    // While output buffering is cool, doesn't have any value here...
    ob_start();
    // use call_user_func to call the function name we passed in...
    call_user_func($func_name);
    $rota = ob_get_clean();

    echo $rota;
}

// Results:
turismo('be_comu');
// outputs "BE"

turismo('cn_comu');
// outputs "NE"

turismo('non_existent_function');
// Outputs "Whoah! Can't call a function that doesn't exist!"
