Here's the SQL - I tested it via command line and it comes back empty
set.
SELECT ID FROM tblItems WHERE number = $place

to

> Instead, I'm getting $result = 4.

> $person in this case is either TRUE or FALSE

So ...
$person = mysql_query("SELECT ID FROM tblItems WHERE number = $place");
$person IS TRUE because query executed (the OR statements do not count
as $person can only be TRUE or FALSE, so you can drop the OR's);
if(!$person){ // tests to see if person IS FALSE
$result = 1;
} else {
$result = 4;
}
$result will be 4
If you do this;
if($person){ // tests to see if person IS TRUE
$result = 1;
} else {
$result = 4;
}
$result would be 1
Now, if you used mysql_num_rows($person)
$thecount = mysql_num_rows($person);
if($thecount == 0){ // tests for zero
$result = 1;
} else {
$result = 4;
}
$result will be 1
if(!$thecount == 0){ // tests for other than zero
$result = 1;
} else {
$result = 4;
}
$result will be 4
