I am sanitizing a text field input via a custom WordPress Setting API page like this...

public function current_issue_sanitize($input) {
    $sanitary_values = array();
    if ( isset( $input['episode'] ) ) {
        $sanitary_values['episode'] = sanitize_text_field( $input['episode'] );

    return $sanitary_values;

This is working well but I am now trying to sanitize and integer, is there a sanitize_text_field equivalent for numbers?

    Why can't you use sanitize_text_field() on integers? If you want to return the int part of the value, you can use $sanitary_values['episode'] = ( int ) sanitize_text_field( $input['episode'] );

If the integer should be a positive number, you can use absint(). See: https://codex.wordpress.org/Function_Reference/absint
