imagecreatefromgif() and imagegif()

[Jabop]

I have looked around the web, but can't find any information on why this successfully outputs a gif image, but fails on the animation.

 

<?php
header("Content-type: image/gif");
$img=imagecreatefromgif($AnimatedGif);
imagegif($img);
imagedestroy($img);
?>

 

Could anyone lend some assistance?

I don't think PHP can do animations properly, but I could be wrong.  =/  I'll do some searching.

The GD library functions only operate on one image at a time. To process animated gifs, you would need to use one of the existing classes (or write your own).

 

If you are only reading and outputting the image file without any processing, there is no need to go through the GD functions.

What would you propose I do then? I messed around with fopen() and tried to get something to work using that method, but I thought gd would be easier.

If you are only outputting the image, after your content-type header, any of the following would work -

 

readfile($AnimatedGif);

 

$contents = file_get_contents($AnimatedGif);
echo $contents;

 

$handle = fopen($AnimatedGif, "rb");
$contents = fread($handle, filesize($AnimatedGif));
fclose($handle);
echo $contents;

 

If you have code that does not work, post it and the symptoms/errors to get help with what it is or is not doing.

Thanks PFMaBiSmAd. I tried the third option because I understood it the most off the bat, however, I don't have time to do benching on the other two methods right now. Which would be processed fastest? Which is the best method to use?
