bitwise help please

[travis]

alright,

basically I have a flag in my script that can have any or all of about 2000 different conditions.

ex.

$flag can contain any numbers from 1-2000 or all of 1-2000 different number conditions.

 

i used to code alot for amxx which was basically small coding and you could easily use a bitsum variable to get this done without messy arrays.

ex.

status_flags |= (1 << 15); // add condition 15
status_flags |= (1 << 100); // add condition 100
status_flags |= (1 << 1051); // add condition 1051
for (i = 0; i < 2000; i++)
if (status_flags & (1 << i)) // check for condition #
	print i;

and this code wound print 15 100 1051

 

i know all these operators are in php aswell but when i try the same principal in php it doesnt work the same.

$status_flags |= (1 << 15); // add condition 15
$status_flags |= (1 << 100); // add condition 100
$status_flags |= (1 << 1051); // add condition 1051
for ($i = 0; $i < 2000; $i++)
if ($status_flags & (1 << $i)) // check for condition #
	print $i . "<br>";

the if statement does work on 15 100 1051 but it also work on about 100 other numbers too.

ill show the first few for the ex

so my question is that if the bit var isnt going to work what are my other options to achieve this?

but I would perfer the bit

any and all help is welcome and apprieated

Here is some code I used for user permissions many years ago where I stored in integers but needed to get the individual rights.

function CheckRights($right,$opid,$force=0) // Notifications
{
if(!isset($_SESSION['oprights']) || $force)
	$oplevel=GetSubadminRights($opid);
else
	$oplevel=$_SESSION['oprights'];
    $rgtstr="";
    for($i=0;$i<30;$i++)
    {
    	if((pow(2,$i) & $oplevel) == pow(2,$i))
        {
        	$rgtstr=$rgtstr . "1";
        }
        else
        {
        	$rgtstr=$rgtstr . "0";
        }
}
    //echo($rgtstr);
    for($i=0;$i<30;$i++) 
    {
    	$chkarr[]=substr($rgtstr,$i,1);
    }
//return 1;
    return($chkarr[$right]);
}
function GetSubadminPRights($opid)   // Permissions
{
global $link;

    $query=sprintf("select permissions,masteradmin from turnkeys_admin where uid=%d",$opid);
    $opResult=mysql_query($query,$link) or die(mysql_error()."--".$query);
    $opRow=mysql_fetch_row($opResult);
    $opLevel=$opRow[0];
// $masteradmin = $oprow[1];
// if($masteradmin) $opLevel = 134217726;  // set all permissions for master admin - disregard settings
    // Save in session
if($opid == $_SESSION['user_id'])
	$_SESSION['opprights'] = $opLevel;
    
    return($opLevel);
}

 

Hope it helps
