Question

PHP

Actually, the question is in the title. And what is better to use instead?

Answer 1

You can use. But not recommended.
There are two reasons:
What to use instead, in descending order of preference:

1. ORM and QueryBuilder from the framework you use, like laravel.com/docs/4.2/eloquent
   
2. Normal wrapper with placeholder support, such as phpfaq.ru/safemysql
   
3. If you absolutely can’t give up the habit of working directly with API functions, then PDO, phpfaq.ru/pdo
   

Answer 2

php.net/manual/en/function.mysql-connect.php
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
mysqli_connect()
PDO::__construct()

Answer 3

Outdated. Removed in php 5.5 and above. Learn PDO.

Answer 4
