布尔值保存为mysql中的tinyint（1）

Question

I made table with some Boolean fields.

CREATE TABLE PM_ADMIN_LIST(
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(250) NOT NULL,
password VARCHAR(250) NOT NULL,
mail VARCHAR(250) NOT NULL,
added_time INT,
super_admin VARCHAR(250) NOT NULL,
last_time INT,
last_ip VARCHAR(250),
see_user_per BOOLEAN DEFAULT FALSE,
change_user_per BOOLEAN DEFAULT FALSE,
see_people_per BOOLEAN DEFAULT FALSE,
change_people_per BOOLEAN DEFAULT FALSE,
add_people_per BOOLEAN DEFAULT FALSE,
remove_people_per BOOLEAN DEFAULT FALSE,
see_album_per BOOLEAN DEFAULT FALSE,
add_album_per BOOLEAN DEFAULT FALSE,
change_album_per BOOLEAN DEFAULT FALSE,
remove_album_per BOOLEAN DEFAULT FALSE,
see_music_per BOOLEAN DEFAULT FALSE,
add_music_per BOOLEAN DEFAULT FALSE,
change_music_per BOOLEAN DEFAULT FALSE,
remove_music_per BOOLEAN DEFAULT FALSE,
admin_per BOOLEAN DEFAULT FALSE,
yahoo_per BOOLEAN DEFAULT FALSE,
status_per BOOLEAN DEFAULT FALSE,
pm_per BOOLEAN DEFAULT FALSE,
ip_blocking_per BOOLEAN DEFAULT FALSE
);

But when I check it in phpmyadmin, BOOLEAN fields are tinyint(1) and they are 0 by default. I can make 1 to be TRUE. But when I use === in my PHP code, they can't be converted. (I should use == in if, for, while and I think it can make some bug in my system.)

So, how should I solve it? How should I get it BOOLEAN by default from mysql?

Answer 1

You usually don't get anything but strings in PHP when fetching data from the database. The types are solely used on the database side.

The field is a TINYINT because MySQL doesn't contain a BOOLEAN field at all.
