Changing page background in PHP according to time

[MegaSonicX]

OK so I'm making a site and I want to use PHP to make the background change according to the time. I tried this code but it doesn't work:

index.php

Code: Select all

<?php
$hour = date('H');
if ($hour < 12 ) {
    echo '<link rel="stylesheet" type="text/css" href="style.css" />;
}
elseif ($hour < 12 ) {
    echo '<link rel="stylesheet" type="text/css" href="style2.css" />';
}
elseif ($hour < 17 ) {
    echo '<link rel="stylesheet" type="text/css" href="style3.css" />';
}
else {
   echo'You messed up man.';
}
?>


And this is the CSS

style.css

Code: Select all

body {
background-image:url('background.png');
}


They're both in a folder called time.png
Please help me!

Check my comment on the code

Code: Select all

<?php
$hour = date('H');
if ($hour < 12 ) { /***** if $hour is between 0 to 12 ****/
    echo '<link rel="stylesheet" type="text/css" href="style.css" />;
}
else if ($hour > 13 AND $hour < 17 ) { /***** if $hour is between 12 to 16 ****/
    echo '<link rel="stylesheet" type="text/css" href="style2.css" />';
}
else if ($hour < 18 ) { /***** if $hour is between 17 to 24 ****/
    echo '<link rel="stylesheet" type="text/css" href="style3.css" />';
}
else {
   echo 'You messed up man.'; /***** supose that $hour not defined ****/
}
?>
