            public static $favSport = "Football";

 public static function
            watchTV()
 {
 echo "Watching ".static::$favSport;

            }
}


class Executive extends Employee
            
{
 public static $favSport =
            "Polo";
}

echo
            Executive::watchTV();

Parse error: syntax error, unexpected T_STATIC on line
7

Why
do I get parse error & and how to fix it? Thanks!

Answer

The parse error
here:

echo "Watching
            ".static::$favSport;

is
because rel="nofollow noreferrer">late static bindings were introduced in PHP v5.3.
Your php version (<5.3) doesn't recognize
static::$favSport.

There
isn't any way I can think of to fix it for PHP older than 5.3, other than with object
inheritance (which isn't really a fix per se since it doesn't have
anything to do with static)...
