Mysql extension & functions are removed from php 7, see http://stackoverflow.com/questions/13944956/the-mysql-extension-is-deprecated-and-will-be-removed-in-the-future-use-mysqli — jiboulex, Jan 25 '16 at 10:19

You have to install a previous version of PHP. It's the only way, I think — fusion3k, Jan 25 '16 at 10:46
Stop using the **deprecated and as of PHP7 removed** mysql_* functions. Migrate to PDO and start using Prepared Statements, it really isn't hard. http://jayblanchard.net/demystifying_php_pdo.html — Charlotte Dunois, Jan 25 '16 at 10:52
@charlotte-dunois if he need-it for testing reasons (he says it) it's not bad, it's mandatory. — fusion3k, Jan 25 '16 at 10:56

when you have code that use mysql, you should change your PHP version below PHP7 like php 5 because these function deprecated in oldest version of PHP so the code shouldn't be built on these mysql functions and will be removed from newest versions.
