keep in mind that this function is prone to an overflow, and on big filesystems it will return negative values.

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.
