  • 0

I am trying to create a html page that uses a php page to decide what image to display at a set time.

The only problem is when i go to the php page it will display the correct image, but when i try to img src the php page, it gives a dead link on the HTML page. Here is the code I am using on the HTML and PHP page.

HTML:

<html>
<body>
<img src="http://itcacher85.hostzi.com/getImage.php" />
</body>
</html>

getImage.php:

<?php
header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
header('Expires: January 01, 2013'); // Date in the past
header('Pragma: no-cache');

$h = date('Hi');

if ($h >= 2100 && $h < 2230){ $img = '40px-Dni5.png'; }
elseif ($h >= 2230 && $h < 0000){ $img = '40px-Dni3.png'; }

elseif ($h >= 0000 && $h < 0130){ $img = '40px-Dni7.png'; }
elseif ($$h >= 0130 && $h < 0137){ $img = '40px-Dni6.png'; }

elseif ($h >= 0137 && $h < 0138){ $img = '40px-Dnisolve.png'; }
elseif ($h >= 0138 && $h < 0300){ $img = '40px-Dni6.png'; }

elseif ($h >= 0300 && $h < 0430){ $img = '40px-Dni4.png'; }
elseif ($h >= 0430 && $h < 0600){ $img = '40px-Dni5.png'; }

else{ $img = 'where.png'; }
?>

<img src="<?php echo $img; ?>">

This code will display the image fine if you go to the PHP page, but when you link it as an image it does not work. I did a little research and found that I might need to add a header:

header('Content-type: image/png');

but when I add that in i get a dead link and no image is displayed on either the php page or the HTML page. Any help would be greatly appreciated.

    That’s not how images work. You need to output the image’s data, not another HTML fragment.

    <?php
header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
header('Expires: January 01, 2013'); // Date in the past
header('Pragma: no-cache');
header('Content-Type: image/png');

$h = date('Hi');

if ($h >= 2100 && $h < 2230){ $img = '40px-Dni5.png'; }
elseif ($h >= 2230 && $h < 0000){ $img = '40px-Dni3.png'; }

elseif ($h >= 0000 && $h < 0130){ $img = '40px-Dni7.png'; }
elseif ($h >= 0130 && $h < 0137){ $img = '40px-Dni6.png'; }
# HEY!  ^ LOOK OVER HERE! ... too many $ signs.

elseif ($h >= 0137 && $h < 0138){ $img = '40px-Dnisolve.png'; }
elseif ($h >= 0138 && $h < 0300){ $img = '40px-Dni6.png'; }

elseif ($h >= 0300 && $h < 0430){ $img = '40px-Dni4.png'; }
elseif ($h >= 0430 && $h < 0600){ $img = '40px-Dni5.png'; }

else{ $img = 'where.png'; }

readfile($img);
?>
