1 - Character Formatting
- All special non-whitespace HTML characters are displayed as-is. Exceptions below.
 - See Emphasis.
 - There's no syntax for font tags or color attributes.
 The tilde '~' is the Escape Character:
- A single tilde '~' followed by nothing gets rendered as a single tilde. => ~
 - Two tilde '~~' get rendered as a single tilde. => ~
 - A single tilde before a link ('~http://foo.bar') prevents linking.
 
=> http://foo.bar
- Two tildes before a link ('~~http://foo.bar') produce a tilde
 
followed by the hyperlinked URL. => ~
http://foo.bar- A tilde inside an URL gets removed, unless it's formatted inside
 
[ ] brackets. Two tildes inside an URL (without brackets) become a single tilde. =>
http://foo.bar/~user or 
http://foo.bar/~user- Special non-ascii or non-latin characters are printed as-is only if supported
by the native wiki CHARSET. Add such characters on a non-supported CHARSET with the RawHtmlPlugin? if it is enabled by the Admin and e.g. the &#num; syntax. 
E.g. These japanese euc-jp chars 'から 新規ページ' on this utf-8 wiki. And with the plugin:The 'RawHtml' plugin is blocked by administrator. Sorry for the inconvenience
And this is how it should like:
 
2 - Paragraphs
- Don't indent paragraphs
 - Words wrap and fill as needed
 - Use blank lines as separators
 - Four or more minus signs make a horizontal rule
 - %%% or <br> makes a linebreak (in headings and lists too)
 
3 - Lists
asterisk for first level
- indented asterisk (indent at least two spaces) for second level, etc.
 
- Use *, -, + or o for bullet lists, # for numbered lists (mix at will)
 Definition lists:
Term: definition
gives
- Term
 - definition
 
as in the <DL><DT><DD> list
- Items may contain multiple paragraphs and other multi-lined content, just indent the items
 
4 - Headings
- '!' at the start of a line makes a small heading
 - '!!' at the start of a line makes a medium heading
 - '!!!' at the start of a line makes a large heading
 
5 - Preformatted text
Place preformatted lines inside <pre>:
<pre> Preformatted text. WikiLinks still work. </pre>
gives
Preformatted text. WikiLinks? still work.If you want text with no Wiki interaction, use the <verbatim> tag:
<verbatim> Preformatted text. WikiLinks do not work. </verbatim>
gives
Preformatted text. WikiLinks do not work.
6 - Indented Paragraphs
Two or more whitespaces signal indented text. Indents may be nested.
This is an indented block of text.
This block is even more indented.
E-mail style block-quoting is supported as well:
> This is block-quoted text.
renders as
This is block-quoted text.
7 - Emphasis
- Use an underscore (_) for emphasis (usually italics)
 - Use an asterisk (*) for strong emphasis (usually bold)
 - Mix them at will: bold italics
 Emphasis can be used multiple times within a paragraph, but cannot cross paragraph boundaries:
_this
will not work_
8 - References
- Hyperlinks to other pages within the Wiki are made by placing the page name in square brackets: this is a page link? or UsingWikiWords? (preferred)
 - Hyperlinks to external pages are done like this:
http://www.wcsb.org/ - You can name the links by providing a name, a bar (|) and then the
hyperlink or pagename:
PhpWiki home page ---
the front page - You can suppress linking to old-style references and URIs by preceding the word with a '~', e.g. NotLinkedAsWikiName, http://not.linked.to/
 - Also, the old way of linking URL's is still supported: precede URLs
with "http:", "ftp:" or "mailto:" to
create links automatically as in: 
http://c2.com/ - URLs ending with .png, .gif, or .jpg are inlined if in square brackets, by themselves.
 In-page hyperlinks are made by placing a named anchor and referring to the anchor in a hyperlink:
Named anchors:
- #[foo]: An anchor around the text "foo" with id "foo".
 - #[|foo]: An empty anchor with id "foo".
 - #[howdy|foo]: An anchor around the text "howdy" with id "foo".
 
- References to name anchors are made thusly:
[##hyperlinks], [OtherPage#foo], [named|OtherPage#foo]. 
9 - Tables
Definition list style tables are written just like definition lists, except that you replace the trailing colon on the term with a "pipe" (|).
Term 1 | Definition 1 begins here. Term 1.1 | Definition 1.1 Term 1.2 | Definition 1.2 This is part of definition 1. Term 2 | Here's definition 2.Term 1 Definition 1 begins here.
Term 1.1 Definition 1.1 Term 1.2 Definition 1.2 This is part of definition 1.
Term 2 Here's definition 2. - Old-style tables are supported through the OldStyleTablePlugin:
 
10 - HTML Mark-Up Language
- Some in-line markup is allowed through the use of HTML tags:
b, big, i, small,
tt, em, strong,
abbr, acronym, cite,
code, dfn, kbd, samp, var, sup and sub - < and > are themselves
 - The & characters will not work
 
11 - Creating various kinds of special links
- See MagicPhpWikiURLs? for gory details on how to write various kind of wiki maintenance and other special links.
 
12 - Inserting plugins
Several plugins permit embedding additional functionality to Wiki pages. For example,
<?plugin BackLinks page=HomePage info=hits ?>
gives
4 pages link to HomePage: 
 Page Name 
 
 Hits 
 IncludePagePlugin 277 TextFormattingRules 667 RedirectToPlugin 253 OldTextFormattingRules 319 - For more information on plugins see WikiPlugin, and PluginManager for a list of all plugins.
