Question

I have two tables with this structure:

Table one:
ID Description

Table two:
ID Name

I have to echo only the id’s of both tables but i don’t know how to compare.
i can show my idea using a stupid example:

if($id is in the first table  AND $id is in the second table){
echo $id;
echo $description;
echo $name
}

How to do this?
Thanks!

$sql = mysql_query("SELECT t1.*,t2.* FROM table1 as t1, table2 as t2 WHERE t1.id=t2.id AND t1.id='$id'")
while($data = mysql_fetch_array($sql)){
   echo $data["id"];
   echo $data["description"];
   echo $data["name"];
}
