Hi, I'm reading the description of Bitwise Operators on page 81 of "Professional PHP 4", the Wrox book. In the highlighted example on that page, the line of code...
$user_permissions = CREATE_RECORDS | ALTER_RECORDS; the description in the book says that this line is building a set of user permissions out of the previously created constants with the OR operator (I understand what OR means). The value of $user_permissions is set to either 1 or 4, which is in fact 5 (0101). But how is this single line doing that? The explanation was cryptic (to me). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
