Comment:
This is a quite new free host, but Biz.nf project is managed by a well know web development company that has been in free hosting business since 2003. So that, you can probably expect a reliable free host service.

Biz.nf does not put any forced adverts on free hosted sites, so you should expect an ads-free web hosting: with no banners, no popups, etc.

Biz.nf free hosting plan supports almost all common webhosting features, such as CGI, SSI, PHP, email, domains, subdomains, etc. for free.

Though, there are restrictions: smtp is disables, and file size limit is 500 KB, so you can not upload large video/audio files there.

100webspace.com offers large free PHP web hosting plan that includes 100 mb of data storage, 3 gb of monthly bandwidth, free subdomain or domain hosting, 1 MySQL database (5 mb storage), they support CGI, SSI, Perl, POP3 email and many other useful features.

Comment:
100webspace.com is a large and stable free web hosting provider that offers reliable free PHP hosting for years, they provide many useful webhosting features for free and offer a great easy-to-use control panel. The only disadvantage we see at the moment of writing the review is that they add a small banner at the top of each free hosted site. File size limit seams to be 500 KB or so.
