in_array(): Wrong datatype for second argument

[sabret00the]

$grps_ids = explode(' ', trim($bbuserinfo['grps']));
if (!$do)
{
//gonna use this to direct em to the right form
if (in_array($grps_ids, $grps_showgroup['groupid']))
// if (in_array($bbuserinfo[grps], $grps_showgroup['groupid']))
{
// send to leave
$url = "membership.php?$session[sessionurl]do=leavegroup&g=$groupid";
eval(print_standard_redirect('redirect_rightform') );
}
else
{
echo "<!-- ".$grps_showgroup[groupid]." -->";
echo "<!-- ".print_r($grps_showgroup, TRUE)." -->";

// send to join
//$url = "membership.php?$session[sessionurl]do=joingroup&g=$groupid";
//eval(print_standard_redirect('redirect_rightform') );
}

}i don't quite get what i'm doing wrong here, i'm giving it an array then i'm asking it if a number is in there?

yes, you are wrong in this:
if (in_array($grps_ids, $grps_showgroup['groupid']))

you are asking if a value is in an array or not then it's $grps_showgroup (an array) but not $grps_showgroup['groupid'] (specified value)

so it should be the other way round?

yes it should be i just check php.net

thanks deathemporer
