对于MySQL中的用户表，建议使用哪种字段类型和存储引擎？

Question

I have my PhpMyAdmin SQL table for users

Name [id, username, password, email, website, status(1,2), role(1,2)]
Type [INT, VARCHAR, VARCHAR, VARCHAR, TEXT, VARCHAR, VARCHAR]
INDEX [PRIMARY, INDEX, INDEX, INDEX, INDEX, INDEX, INDEX]

How do i fix this? And what Storage Engine do you recommend me to use? And is there a better way for databases that would exceed the limited size? maybe something not Maria Db? or this is the best for PHP?

You should consider:

• Username must be UNIQUE, otherwise it could be created duplicated user names.
• You may consider email as unique (unless a user can create multiple accounts with the same email).
• website could be a varchar(255 or less) field if you dont need a large text for a website url. Also creating a index over a text column is only a good practice if you want full text search. Also you need to specify a index prefix length to avoid a large index file.

You can take a look at https://dev.mysql.com/doc/refman/5.6/en/column-indexes.html for more directions about indexes.
