Referencing a list in a function or class with PHP

Question

thanks in advance for any help. I am new to using classes & functions with php so i'm not quite sure how to go about doing this. I have a list that forms an array and I want to reference it across multiple classes / functions without having to call the list every time. Here is the code I have been working with. How can I put the list & array in a global format that I can use to reference the list in other classes & functions?

class article {


public static function data(){

        list($articles, $articlesMetaData) = getRecords(array(
    'tableName'   => 'articles',
    'where'       => whereRecordNumberInUrl(0),
    'loadUploads' => true,
    'allowSearch' => false,
    'loadCreatedBy'      => true,
    'limit'       => '1',
  ));
  $article = @$articles[0]; // get first record
  if (!$articles) { dieWith404("Record not found!"); } // show error message if no record found

     echo $article['article'];

    }

}

If you want to use list and article as global var you just have to declare them in the body of your code and declare it in your function as global.

<?php
    $article  = null;

    public static function data()
    {
        global $article;
        $article = ...;

$b = $a + $b;

}
