What are the potential pitfalls of using ambiguous field names in SQL queries when joining tables in PHP?

Using ambiguous field names in SQL queries when joining tables in PHP can lead to confusion and potential errors, as the database may not know which table the field belongs to. To avoid this issue, it is recommended to use table aliases in the query to specify which table the field comes from. 

$query = "SELECT t1.id, t2.name 
          FROM table1 t1 
          JOIN table2 t2 ON t1.id = t2.id";
