I know perfectly how numbers are represented and the decimal and binary coding systems.

This is the problem:

after the first replies to this thread I understood that the binary string with all the on-off (0-1) settings was stored as an integer in mysql.

PHP Code:

// Defined constants used for user field. 
$_USEROPTIONS = array( 
    'showsignatures'    => 1, 
    'showavatars'       => 2, 
    'showimages'        => 4, 
    'coppauser'         => 8, 
    'adminemail'        => 16, 


From this code I thought that if I want to see if the signature is enabled i have to check the bit #1, #2 for avatar, #4 for images, #8 for coppa, and #16 for email.

I suppose that the "WHERE options & 16" condition goes to check the bit #16 if is "ON" or "TRUE", or... 1!

Am I wrong?

The other posts (16 or not 16 :P ) confused me a bit...
