    the code line is

    // Avoid the array_slice() if possible. if ( 0 == $the_[‘accepted_args’] ) { $value = call_user_func( $the_[‘function’] ); } elseif ( $the_[‘accepted_args’] >= $num_args ) { $value = call_user_func_array( $the_[‘function’], $args ); } else { $value = call_user_func_array( $the_[‘function’], array_slice( $args, 0, (int) $the_[‘accepted_args’] ) ); }
