See example #2:

It's wondrous what a few minutes googling will find you.

The above is not complete it reads the actual files contents but does not convert it to hexadecimal.

$filename = "c:\\files\\somepic.gif";
$handle = fopen($filename, "rb");
$contents = [u]bin2hex[/u]( fread( $handle, filesize($filename) ) );
fclose($handle);

EDIT:
Oh and use

pack( "H*", $contents );

to convert it back.
