Simple method for recovering redux values if you wish to not use the global variable.

redux_get_variables.php

<?
function redux_get_variables( $name, $key = false ) {
        global $MY_VAR_NAME; // Update to your opt_name or global_variable name
	$options = $MY_VAR_NAME; // Update to your opt_name or global_variable name

	$var = ""; // Set this to your preferred default value

	if ( empty( $name ) && !empty( $options ) ) {
		$var = $options;
	} else {
		if ( !empty( $options[$name] ) ) {	
			if ( !empty( $key ) && !empty( $options[$name][$key] ) ) {
				$var = $options[$name][$key];
			} else {
				$var = $options[$name];
			}
		}
	}
	return $var;
}

// To use this, you'd call anywhere you want redux_get_variables(). 
// You can specify the name of the option by id, and a key within it to return.
