//this code is used to provide an example of how
//a programmer would use the permissions class.
//include the file
require_once("permissions.class.php");
//instanciate the class.
$perms = new permissions();
//the first example shows how you would use the class to set permissions for a user
$perms->permissions["read"]=true;
$perms->permissions["delete"]=true;
$bitmask=$perms->toBitmask();
//echo "bitmask for read and delete= ". $bitmask ."<br>";
$sql ="insert into user_permissions (userid,docid,permission) values($userid,$docid,$bitmask)";
//you would then execute code to insert your sql.
//the second example shows you how to use the bitmask to get the users permissions.
//you would execute some sql to retrieve the bitmask from the database like
//select bitmask from user_permissions where docid=$docid and userid=$userid
//$bitmask = $row["bitmask"];
//I will just set this to a hardcoded value of 5 (as used in all the examples
$bitmask=5;
$permarr=$perms->getPermissions($bitmask);
if($permarr["read"]){
echo "read permissions<br>";
}
//print array to show values
print_r($permarr);
