PHP determines whether the gif image is animated, that is, whether the frame number is greater than 1. The code is as follows:
{ $fp=fopen($filename, 'rb'); $filecontent=fread($fp, filesize($filename));
fclose($fp);
Return strpos($filecontent,chr(0x21).chr(0xff).chr(0x0b).'NETSCAPE2.0')===FALSE?0:1; }
echo IsAnimatedGif("zzsky.gif"); ?>
