Dolphin 7 PHP Requirements Failures

[matthew_history50]

I got Dolphin 7 successfully installed, but it showed a few things that needed to be fixed.

• magic_quotes_gpc = On - FAIL (must be = Off)
• memory_limit = 100663296 - FAIL (must be >= 134217728)
• post_max_size = 33554432 - FAIL (must be >= 52428800)
• upload_max_filesize = 25165824 - FAIL (must be >= 52428800)

How do I change these to be listed as "OK"?

Also Dolphin stated that installing "php accelerator" would benefit me. How do I add this?

Thanks for your help.
