Question

I have

$mySQL = $db -> prepare("SELECT table1.users,table1.name,table2.img,table2.name,table2.users FROM table1,table2 WHERE table1.users = table2.users");

$row = $mySQL->fetch(PDO::FETCH_ASSOC);

I can echo out :

echo $row['name'];

But how does it know to get name from table1 or table2? Can I do something like

echo $row['table1.name'];

Thanks

Also, is this the best way to get data from multiple tables? Thanks

Add alias to identify your table.

SELECT table1.users as tab1user,table1.name,table2.img,table2.name,table2.users as tab2user
 FROM table1 JOIN table2 in table1.users = table2.users

Best way to JOIN tables. it’ll improve performances.
You have to select suitable join method according to your requirement. follow this link for JOIN

Edit :
*JOIN 3 Tables*

 select ......
 FROM table1 JOIN table2 in table1.users = table2.users
 JOIN Table3 in table2.id=table3.id
