php7 and mysql extension

Question

After launching the following code...

<?php
error_reporting(E_ALL);
mysql_connect()
?>

I have Uncaught Error: Call to undefined function mysql_connect() in log.

The first thing that comes in mind is to do sudo apt-get install php-mysql but it outputs

Reading package lists... Done
Building dependency tree
Reading state information... Done
php-mysql is already the newest version

after that I did dpkg --list | grep mysql and it said that php-mysql and php7.0-mysql are installed.

What is wrong here?

PS. PHP version is 7.0.8.

Call to undefined function mysql_connect

The mysql_ library was deprecated years ago. It has been removed entirely in PHP 7.

Use a modern replacement such as PDO or mysqli_.

You need to use the mysqli_* functions, not mysql_*.

You're trying to say that there's no `mysql_*` functions in `PHP7`? – Eugeny89 Oct 04 '16 at 13:09

@Eugeny89 if you're switching to `mysqli_*` you should probably use the `mysqli` class with parameterized queries. – Thomas Oct 04 '16 at 13:13
