How can ambiguous column errors be resolved in PHP when using JOIN in MySQL queries?

Ambiguous column errors in PHP when using JOIN in MySQL queries can be resolved by specifying the table name along with the column name in the SELECT statement. This helps MySQL understand which table's column you are referring to when there are columns with the same name in multiple tables involved in the JOIN. 

$query = "SELECT table1.column_name, table2.column_name FROM table1 JOIN table2 ON table1.id = table2.id";
$result = mysqli_query($connection, $query);

if($result){
    // Process the query result
} else {
    echo "Error: " . mysqli_error($connection);
}
