Sample function that generates apache 2.2 ETag. Useful for scripts serving images or other cachable data.
$file="example.png";
// Inode
$ETag = dechex(fileinode($file));
// Size
$ETag.= "-".dechex(filesize($file));
// Modification time in useconds & (2^33-1)
$ETag.= "-".dechex(((filemtime($file).str_repeat("0",6)+0) & (8589934591)));
header("ETag: \"$ETag\");

This function, in spite of its name, also works for directories. Most any valid path in the filesystem will generate an inode value.
