It finally works.
this little function, bin2mysqlhex that I wrote, has saved my bacon on file
uploads to a BLOB type in a database. I can't seem to get anything else to
work. note that when you do an INSERT or UPDATE..SET, you don't use quotes
on the data.

function bin2mysqlhex($s ) {
$a='0x';
$q=array('0','1 ','2','3','4',' 5','6','7','8', '9','A','B','C' ,'D','E','F');
for($x=0; $x<strlen($s); $x++) {
$a .= $q[ord($s{$x})>>4]; //msb
$a .= $q[ord($s{$x})&0x0 f]; //lsb
}
return $a;
}
