使用 DEFAULT 关键字:

Use the DEFAULT keyword:

$query = "INSERT INTO myTable VALUES (DEFAULT,'Fname', 'Lname', 'Website')";

此外，您可以指定列，(这是更好的做法):

Also, you can specify the columns, (which is better practice):

$query = "INSERT INTO myTable
          (fname, lname, website)
          VALUES
          ('fname', 'lname', 'website')";
