PHP determines whether the GIF picture 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");?>
