Q: Worpdress - How to keep custom variables? I want to keep some theme variables in config class. But I get an error when tring to use esc_html__( 'Facebook' ) function.
What is the best way to store custom variable in class? And why I cannot use esc_html__ function?
class config
{
    static $vConfig = array(        
        'colors' => array(
            'body' => '#f6f6f6'
        ),
        'social' => array(
            'facebook' => esc_html__( 'Facebook' )
        )
    );  
}

Here is an error message:
Parse error: syntax error, unexpected '(', expecting ')' in ...
