Question

I want to match a string var named “$ip” to a column name “ip” in “$Hood” table.
If there isn’t a match then do something.

So I have this code:

if (mysql_query("IF EXISTS(SELECT TOP 1  1 FROM $Hood WHERE ip=$ip)") == 1) 

And it’s not working, it suppose to return 1 because there is a match.
What’s wrong here?

Answer 1

simply select the matching ip form the DB like so:

SELECT ip 
FROM $hood 
WHERE ip='$ip' 
LIMIT 1

and count the rows, if it is equal to 1 then you have a match, 0 otherwise, like so:

if(mysql_num_rows(mysql_query(SELECT ip FROM $hood WHERE ip='$ip' LIMIT 1)) == 1)
