PhpWiki is written in the server-side scripting language PHP, available from http://www.php.net/. PHP resembles C and Perl in its syntax, and functions much like ASP, EmbPerl or JSP.

PhpWiki consists of a dozen or so files of mixed PHP and HTML. The web pages that make up a WikiWikiWeb based on PHP live in a database with backup copies of previous versions of pages stored as well. (For the database, PhpWiki works with DBM, MySQL, PostgreSQL or text files.)

Every time a user hits the site, the page requested is pulled from the database and rendered on the fly. The user only really ever requests the file index.php, which then decides which other php files to include.

Links to pages in the Wiki are automatically linked: AddingPages. This might be the single most compelling aspect of a Wiki, the ability to add pages simply by linking to them. The next most compelling thing is how easily external URLs link, like this:

  1. http://www.wcsb.org/
  2. ftp://ftp.redhat.com/
  3. news://news.mozilla.org/
  4. http://slashdot.org/
  5. http://theregister.co.uk/

Combined with one namespace and a simple markup, a Wiki exhibits many of the characteristics of WabiSabi.
