A few errors with my first installation

Hi

Just set up my first site with code igniter and I got these errors. Are they anything to worry about.

This has been set up on my localhost just for dev purposes.

Code:

A PHP Error was encountered

Severity: 8192

Message: Function set_magic_quotes_runtime() is deprecated

Filename: codeigniter/CodeIgniter.php

Line Number: 60
A PHP Error was encountered

Severity: 8192

Message: Assigning the return value of new by reference is deprecated

Filename: libraries/Loader.php

Line Number: 255

Thanks in advance :-)
