I recently asked a question that resulted in people telling me to use "PDO" over MySQL. Why is that? What advantages does it have over the other?

Answer 1

The mysql_* functions are no longer maintained and community has begun the deprecation process. Instead you should learn about prepared statements and use either PDO or MySQLi.

If you cannot decide, this article should help you choose. Though, you should know, that PDO is able to work with different kinds of RDBMS, while MySQLi is made for a specific one.

In case you decide to go with PDO, it's recommended you follow this tutorial.
