latest versions of PHP, no longer use the driver "mysql_" I advise using PDO or mysqli.
When i learned coding 6 yrs back. I had a gap of 2 yrs from coding . I am backdated now. Can u pl tell the advantages of mysqli ?
Mysqli:
The mysql driver only connects to a database. MySQL = D.

PDO:
The PDO he makes 12 kinds of database, if not mistaken.

Performance:
In terms of performance, mysqli, out in front, but the difference is minimal.

Recommendation:
I recommend using the PDO, by its advantages connections in various database, this can help in the future if you want to migrate to another database.
