[PHP] I want to know if some link is online

[Jesús Alain Rodríguez Santos]

I would like to know if a web is online, a have this code:

enlace.php

?
$vivo = verde.gif;
$muerto = rojo.gif;

$enlinea = fopen($enlace, r);
 if (!$enlinea){
header(Location: $muerto);
}
 else {
   header(Location: $vivo);
  }
fclose($enlinea);
?

In other page  I hve this:

page.php

img src=estado.php?enlace=http://www.cfg.jovenclub.cu;

Somebody can tell me what it's wrong, because the image did not
show, of course that the pages and bouth image are in the same
dorectory.
Please any suggestion

Why not use file_exists()? Also, you probably want to use 
$_GET['enlance'] rather than $enlance.



 if (!$enlinea){
header(Location: $muerto);
}


You need to specify an absolute URI here 
(http://www.example.com/myimage.gif for example).
