En respuesta al amigo Yranac, les colocare el ode completo del php. bueno creo yo que el pedazo que les habia puesto era necesario, pero porsi, salgamos de dudas.
y en respuesta a lo otro, bueno miren, ya probe los dos codigos y no hubo ningun cambio, nisiquiera un mensaje de error, el texto siguio viendose en negro. como si no hubiera hecho algun cambio. veamos si con esto completo se puede hayar una solucion,
gracias a los que me presten unos minutos para ayudarme.
