What if php7 fails to connect to mysql?

Php5 uses the mysql_connect function to connect to the Mysql database, but you will find that this method does not work on php7. The reason is simple: php7 has abandoned this function, and now php7 probably uses two ways to connect to the MySQL database.

Method 1:

Using function concatenation, the original mysql_connect () is changed to the mysqli_connect () function, and everything is fine by adding this letter.

Syntax: variable name = mysqli_connect (host address, user name, password, database name)

Use an object-oriented approach.

Variable name = new mysqli (host address, user name, password, database name)
