Today’s video is “so messy”

Question

I feel that one set of good tutorials is enough, but now there are many tutorials on the PHP Chinese website, which are complicated and messy.

As a novice, after reading several times, I am still talking about mysql_connect, which has been abandoned by php7, to connect to the database.

Answer 1

When I started learning, I looked at my PHP version, gave up MySQL, and started learning MySQL.

Answer 2

I started learning the day before yesterday and had already learned to use mysqli to write user login and registration, and then suddenly discovered The user login system I wrote cannot prevent SQL injection. I learned PDO and then rewrote the user login system using pdo statements. I finished it this afternoon. Listen to me, isn’t PHP Chinese website good? There is a video!
