Quiero compartir un codigo que desarrollé para que lo usen en sus páginas webs: mediante PHP una imagen de día, tarde o noche se mostrará de acuerdo al horario que corresponda.
Código :
<?php
$date = date ("H");
echo "<html><body>";
if ($date < 12) echo "Buenos dias! "."<img src='http://[email protected]/web_movil/img/dia.jpg' title='dia'/>";
else if ($date < 18) echo "Buenas tardes! "."<img src='http://[email protected]/web_movil/img/tarde.jpg' title='tarde'/>";
else echo "Buenas noches! "."<img src='http://[email protected]/web_movil/img/noche.jpg' title='noche'/>";
echo "</body></html>";
?>Explico un poco:
Código :
if ($date < 12) echo "Buenos dias! "."<img src='http://[email protected]/web_movil/img/dia.jpg' title='dia'/>";
(--> Si la variable $date es menor que 12hrs, entonces que imprima la imagen de dia)
El resto es similar, sólo que va a cambiar la imagen.
Las imágenes que cambian son:
- dia.jpg
- tarde.jpg
- noche.jpg
Como sabemos, la hora de PHP se basa en la hora de nuestros hosting o servidor. A mí me marca la hora así:
- a las 12pm --> imagen de dia(dia.jpg)
- a las 6pm --> imagen de tarde(noche.jpg)
- a las 12an --> imagen de mañana(mañan.jpg)
Necesitarán 3 imágenes.
Espero les haya gustado

Se podrá cambiar el diseño de una pagina cuando esta en la mañana, tarde o noche, como las imagenes?

Por otro lado siempre se echa en falta alguna "demo" del final, no?
Un saludo

Igual la idea esta bastante buena saludos!
PD: tal ves se puede hacer con dos imágenes en ves de 3!
Cambiando los tonos de la imagen de la mañana podes hacer la de la tarde. y la de la noche conviene que sea la de la noche

<html>
<body>
<?php include 'php/clima.php' ?>; <!-- Para que nuestro c´digo se vea mas limpio nuestro codigo, odemos llamarlo desde otro archivo si el PHP de arriba esta en otra ubicación -->
</body>
</html>
luego en una carpeta llamada php(podemos poner el nombre que queramos), en esta carpeta guardamos nuestro archivo llamado clima.php y contiene lo siguiente :
<?php
$hora = date("H"); /* H = Hora de 00 horas a 23 horas por default en PHP, entonces sabiendo esto seguimos abajo*/
if($hora < 12){
$file = ('http://tcc.tutv.com.uy/weatherSubrayado/images/Weather/tiempo_sol_small.png');
$mensaje = "Buenos Dias";
}
else if($hora < 1
$file = ('http://tiempovenezuela.com/assets/images/weather_yr/3.png');
$mensaje = "Buenas Tardes";
}
else{
$file = ('http://www.cuandopasa.com/pic/n/000/000/n0000000130zgk.jpg');
$mensaje = "Buenas Noches";
}
?>
<?=$mensaje?>
<img src="<?=$file?>";
listo, como dije gracias a todos por sus criticas y opiniones, voy a tratar de crear otra aplicación y ojala tambien les guste.
Por ejemplo:
$file = ('http://www.nuevaubicacion.com/dia.jpg');
saludos
<?php
$hora = date("H"); /* <-- H = Hora de 00 horas a 23 horas por default en PHP, entonces sabiendo esto seguimos abajo*/
if($hora < 12){
$file = ('http://tcc.tutv.com.uy/weatherSubrayado/images/Weather/tiempo_sol_small.png');
$mensaje = "Buenos Dias";
}
else if($hora < 1
$file = ('http://tiempovenezuela.com/assets/images/weather_yr/3.png');
$mensaje = "Buenas Tardes";
}
else{
$file = ('http://www.cuandopasa.com/pic/n/000/000/n0000000130zgk.jpg');
$mensaje = "Buenas Noches";
}
?>
<html>
<body>
<?=$mensaje?> <-- También podemos llamarlo desde otro archivo si el PHP de arriba esta en otra ubicacion como dije antes de este mensaje !
<img src="<?=$file?>";
</body>
</html>

no olvidar que utiliza la hora del servidor, por tanto no es lo mismo que utilizar la hora de la pc con javascript.
