#1 Apache Rewrite 技术
Apache Rewrite 技术
--------------------------------------------------------------------------------
作者：忘了
Apache 特有的 rewrite 技术很好用，Vovo2000.Com 的
/gallery/
/vovo-gallery/
/phpbb2/
/linka/
...
都已经彻底嵌入 rewrite。 Rewrite 很简单的说，就是把类似
==> /phpbb2/viewtopic.php?t=1388&start=0
动态网页，转成
==> /phpbb2/viewtopic-1388-0.html
好处有：
1. URL 短一点，静态网址的接受度较高。
2. Search Engine 比较吃的下去～
3. 静态的网址会有比较好的 SE-BENCHMARK
===========================================
===========================================
在这里举 PHPBB2 2.0.3 的例子来说，一步一步来：
1. 把 Apache 的 Rewrite 打开（mod_rewrite）
2. 在 phpbb/include/page_header.php
的 // Generate logged in/logged out status 之前加入
代码:
ob_start();
function replace_for_mod_rewrite(&$s)
{
$urlin = array(
"'(?<!/)viewforum.php\?f=([a-zA-Z0-9]+)&topicdays=([0-9]*)&start=([0-9]*)'",
"'(?<!/)viewforum.php\?f=([a-zA-Z0-9]+)&mark=topics'",
"'(?<!/)viewforum.php\?f=([a-zA-Z0-9]+)'",
"'(?<!/)viewtopic.php\?t=([0-9]+)&view=previous'",
"'(?<!/)viewtopic.php\?t=([0-9]+)&view=next'",
"'(?<!/)viewtopic.php\?t=([0-9]+)&postdays=([0-9]*)&postorder=([a-zA-Z]*)&start=([0-9]*)'",
"'(?<!/)viewtopic.php\?t=([0-9]+)&start=([0-9]*)'",
"'(?<!/)viewtopic.php\?t=([0-9]+)'",
"'(?<!/)viewtopic.php\?p=([0-9]+)'",
"'(?<!/)profile.php\?mode=viewprofile&u=([0-9]+)'"
);
$urlout = array(
"viewforum-$1-$2-$3.html",
"forum-$1.html",
"forum-$1.html",
"prev-topic-$1.html",
"next-topic-$1.html",
"viewtopic-$1-$2-$3-$4.html",
"viewtopic-$1-$2.html",
"viewtopic-$1.html",
"viewpost-$1.html",
"profile-$1.html"
);
$s = preg_replace($urlin, $urlout, $s);
$s = mb_ereg_replace( "viewtopic-([0-9]+).html&(.*)$", "viewtopic.php?t=\\1&\\2", $s);
return $s;
}
3. 在 phpbb/include/page_tail.php
代码:
在下列?#123;式之后：
$db->sql_close();
?#91;入：
$contents = ob_get_contents();
ob_end_clean();
echo replace_for_mod_rewrite($contents);
global $dbg_starttime;
在下列?#123;式之后：
ob_end_clean();
?#91;入：
echo replace_for_mod_rewrite($contents);
global $dbg_starttime;
4. 接下来当然要建立 .htacce 的 rewrite rule
代码:
RewriteEngine On
RewriteRule ^viewforum-([0-9a-zA-Z]+)-([0-9]+)-([0-9]+)\.html$ viewforum.php?f=$1&topicdays=$2&start=$3
RewriteRule ^forum-([0-9a-zA-Z]+)\.html$ viewforum.php?f=$1&mark=topic
RewriteRule ^forum-([0-9a-zA-Z]+)\.html$ viewforum.php?f=$1
RewriteRule ^prev-topic-([0-9]+)\.html$ viewtopic.php?t=$1&view=previous
RewriteRule ^next-topic-([0-9]+)\.html$ viewtopic.php?t=$1&view=next
RewriteRule ^viewtopic-([0-9]+)-([0-9]+)\.html$ viewtopic.php?t=$1&start=$2
RewriteRule ^viewtopic-([0-9]+)-([0-9]+)-([a-zA-Z]*)-([0-9]+)\.html$ viewtopic.php?t=$1&postdays=$2&postorder=$3&start=$4
RewriteRule ^viewtopic-([0-9]+)\.html$ viewtopic.php?t=$1
RewriteRule ^viewpost-([0-9]+)\.html$ viewtopic.php?p=$1
RewriteRule ^viewtopic-([0-9]+)\.html&highlight=(.*)$ viewtopic.php?t=$1&highlight=$2
RewriteRule ^profile-([0-9]+)\.html$ profile.php?mode=viewprofile&u=$1
5. 测试～ 当然 OK；
供各位参考，善用 Rewrite 让您的动态网站更美观、更一致、更方便被「吃」 。
