function pageBanner() can have an array from page

Under page.php:

<?php
get_header(); 
    while(have_posts()){
        the_post(); 
        //Page Banner From Function.php
        pageBanner(array(
            //name can be named to whatever
            //function is called with an array inside inyects in to
            //pageBanner() @funtions.php
            'title' => 'Hello there title',
            'subtitle' => 'Hello there subtitle',
            'photo' => get_theme_file_uri('/images/ocean.jpg')
        ));
?>

under functions.php

//Load Banner For All Pages
//$args = NULL, if there is no data inyected, function still would work cause in any case it defaults to NULL
function pageBanner($args = NULL){ 
    //if $args doesn't come with title, default to default
    if (!isset($args['title'])){
        $args['title'] = get_the_title();
    }
    //if $args doesn't come with subtitle, default to default
    if (!isset($args['subtitle'])){
        $args['subtitle'] = get_field('page_banner_subtitle');
    }
    //if $args doesn't come with photo, default to default
    if (!isset($args['photo'])){
        if (get_field('page_banner_background_image') AND !is_archive() AND !is_home()) {
            $args['photo'] = get_field('page_banner_background_image')['sizes']['pageBanner'];
        } else {
            $args['photo'] = get_theme_file_uri('/images/ocean.jpg');
        }
    }    
?>
    <!--Banner Start-->
