php和sqlite insert语句的语法问题

This code gives me an error when I try to insert Cat and Purr. The tutorial didn't have a double quotation mark, but their code didn't work either. This has to be a syntax issue of some sort.

message('creating the db Object');
    $db = new bwSQLite3(DB_FILENAME, TABLE_NAME);
    $tn = TABLE_NAME;
    message('creating the table');
    $db->sql_do("Drop table if exists $tn");
    $db->sql_do("create table $tn ( id integer primary key, animal text, sound text )");
    //insert some records
    $db->sql_do("insert into $tn (animal, sound) values (?, ?), 'cat', 'Purr' "); //right here issues
    $db->sql_do("insert into $tn (animal, sound) values (?, ?), 'dog', 'Woof' ");
    $db->sql_do("insert into $tn (animal, sound) values (?, ?), 'duck', 'Quack' ");
    $db->sql_do("insert into $tn (animal, sound) values (?, ?), 'bear', 'Grr' ");
    message('there are %d rows in the table', $db->count_recs());
}catch (PDOException $e) {
    error($e->getMessage());
}

Here is the error: Parse error: syntax error, unexpected 'insert' (T_STRING) in C:\xampp\htdocs\ExerciseFiles\Chap01\create.php on line 42

     $db->sql_do("insert into $tn (animal, sound) values (?, ?), 'cat', 'Purr' "); //right here issues
    

    should be

     $db->sql_do("insert into $tn (animal, sound) values (?, ?)", 'cat', 'Purr'); 
    

    look at the syntax highlighting.

    Also it sounds like you don't understand how PHP works with strings, try this to see the difference:

    $my_name = 'Matt';
    echo 'Hello $my_name.';
    echo "Hello $my_name.";
