PHP – use Global Variables in Class

global $wpdb;
$WP_GLOBALS = array(
    'table_name' => $wpdb->prefix . 'organisations'
);
 
class Organisations {
 
    // Instantiate new variable in class
    protected $glob;
 
    public function __construct() {
 
        // Self explanatory
        global $WP_GLOBALS;
        $this->glob =& $WP_GLOBALS;
    }    
 
    public function tableName() {
        return $this->glob['table_name'];
    }
}
 
// Access outside of class
$o = new Organisations();
echo $o->tableName(); // wp_organisation
 
// Set new value for $WP_GLOBALS['table_name'];
$WP_GLOBALS['table_name'] = $wpdb->prefix . 'posts';
echo $o->tableName(); // wp_posts

global $wpdb; $WP_GLOBALS = array( 'table_name' => $wpdb->prefix . 'organisations' ); class Organisations { // Instantiate new variable in class protected $glob; public function __construct() { // Self explanatory global $WP_GLOBALS; $this->glob =& $WP_GLOBALS; } public function tableName() { return $this->glob['table_name']; } } // Access outside of class $o = new Organisations(); echo $o->tableName(); // wp_organisation // Set new value for $WP_GLOBALS['table_name']; $WP_GLOBALS['table_name'] = $wpdb->prefix . 'posts'; echo $o->tableName(); // wp_posts
