Question

I am using MySQL with PHP5. I got to know that ancient mysql_* functions are no longer maintained and community has begun the deprecation process. So I decided to move away from mysql_*. The question is where to? I am looking for lighter, simpler and faster way. Somebody tell me which among these (mysqli and PDO) is;

1. faster
2. easy to learn and code
3. consumes less space and memory

Note: Tutorial links in beginner level for these two will be helpful.

PDO vs. MySQLi: Which Should You Use?

Both PDO and MySQLi offer an object-oriented API, but MySQLi also
offers a procedural API – which makes it easier for newcomers to
understand. If you are familiar with the native PHP MySQL driver, you
will find migration to the procedural MySQLi interface much easier. On
the other hand, once you master PDO, you can use it with any database
you desire!

Ultimately, PDO wins this battle with ease. With support for twelve
different database drivers (eighteen different databases!) and named
parameters, we can ignore the small performance loss, and get used to
its API. From a security standpoint, both of them are safe as long as
the developer uses them the way they are supposed to be used.

So if you’re still working with MySQLi, maybe it’s time for a change!
