Why doesn't PHP communicate with MySQL?

Question

linux

I'm trying to connect to MySQL using the mysql_connect() PHP function, but it doesn't work. The terminal writes the following: PHP Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /var/www/html/1/scripts/connect.php:2
What is the problem and how to solve it?

Answer 1

And why are you using mysql_connect ?
There is no such function anymore, and the error tells you about it in a clear language.
All information is here php.net/manual/ru/function.mysql-connect.php
It is written in Russian.

Answer 2

Install the mysql extension. For php7 - compile (comes as pecl).
In general, it is preferable to use PDO or at least mysqli. But for them, the appropriate extensions need to be installed.

Answer 3

Use MySQL.
