Pseudo-Static is actually the use of PHP to resolve the current address to another method to access the site, to learn pseudo-static rules of the wording, to understand a little regular

First, regular expression tutorial

There is a classic tutorial: Regular expression 30-minute introductory tutorial

The common regular is as follows:

. All characters except line break

\w match letters or numbers or underscores or kanji

\s matches any whitespace character

\d Matching numbers

\b Match the beginning or end of a word

^ Start of matching string

$ match End of string

* Repeat 0 or more times

+ Repeat one or more times

? Repeat 0 or one time

{n} repeats n times

{n,} repeats n or more times

{N,m} repeats n to M times

When the substitution is applied, the match in the previous () is followed by a reference, and the second () matches the $ quote,,,,,

The thing inside this () is called the Atomic group.

Analysis of Discuz SEO htaccess inside the rewrite.

Rewriterule ^forum-([0-9]+)-([0-9]+) \.html$ forumdisplay.php?fid=$1&page=$2

First join the user through linuxidc.com/forum-2-3.html access to the Discuz forum, then first through the. htaccess filter to see if it is needed. htaccess Guide the user if the list of Rewritecond Condition then rewrite it,

Discuz is not listed Rewritecond so it should all be rewritten.

So we started the transliteration,

  Forum-2-3.html this exactly matches the list of

^forum-([0-9]+)-([0-9]+) \.html$

The regular expression. and $2, $3,

So substituting the following, that is, forumdisplay.php?fid=2&page=3 plus the previous rewritebase specified file directory, then take him to the development of the directory forumdisplay.php?fid=2&page=3.
