Gif from ext server

I'm having the same problem that another user had (Ben) and interestingly enough I am also working on a weather related project.

I'm getting this message:

arning: filesize() [function.filesize]: stat failed for (ext server - anim.gif) in /file.php on line 56

Warning: fread() [function.fread]: Length parameter must be greater than 0 in /file.php on line 56

The file that I'm trying to read is an animated gif with 13 frames. It's updated on another web server hourly. I need to download this file into my webserver (of course to the /frames folder).

Did you have any luck fixing Ben's problem? I think mine might be the same.

Thanks,

I thought I would be more clear (just in case).,

I have no problems with the encode script - once the single gif files are located in the /frames directory. My problem is pulling an animated gif from another webserver, chopping it up frame by frame and storing them into the /frames dir.

The default decodeder script isn't working - here is what I have:
$file = "http://www.example.com/animated.gif";
$fp = fread (fopen($file,"rb"), filesize($file));

require "GIFDecoder.class.php";

if ( $fp ) {
$gif = new GIFDecoder ( $fp );
$arr = $gif->GIFGetFrames ( );
$dly = $gif->GIFGetDelays ( );

for ( $i = 0; $i < count ( $arr ); $i++ ) {
fwrite ( fopen ( ( $i < 10 ? "frames/0$i_frame.gif" : "frames/$i_frame.gif" ), "wb" ), $arr [ $i ] );
}
for ( $i = 0; $i < count ( $dly ); $i++ ) {
sprintf ( "Delay of %d frame is %d ms<br>", $i, ( $dly [ $i ] * 10 /* milliseconds */ ) );
}
}

It outputs the errors that I detailed in previous (original) post.

Thanks,

Hi,
My idea that you try to use fsockopen ( ) /Open Internet or Unix domain socket connection/ instead of fopen ( ) /Local file open/.
You can find more references about fsockopen at http://php.net/manual/en/function.fsockopen.php

A simple example from php.net:

<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: www.example.com\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>

Have a nice day!

I'm not sure that I'm understanding if or not I am properly using your code. Even when I put a copy of the anim.gif on my server and use your decode class - I get the same results as if I use "file_get_contents" to pull it from a remote server.

It creates 2 images in the /frames directory:

.gif
0.gif

There are suppose to be 13 frames, but it starts to copy the second frame and "breaks" without giving it a name...

does this sound familiar to you, or have you ran across this issue before?

Thanks,
Brian

Hm, it's very interesting...
Please put an animation file into your server and send me the full path and i try to decode on my server by my decoder class, i would like to test.
