Search engine-oriented URL optimization

I wrote the Jin Far Information Network (www.geofuture.net) did not take into account how the URL to the search engine optimization, completed before the start of optimization. At this point to consider the static on the one hand URL, on the one hand to keep the original program as far as possible to facilitate maintenance later, so the use of Url_rewrite method. The following is the corresponding section of the httpd.conf

I only to the content-oriented column optimization, as for the login and search and other parts remain unchanged, because these parts are also search engines do not care. At the same time, some common status codes (HTTP status) also have corresponding static pages. Only the URL of the foreign request was modified, and the URL generated by the program is implemented in the following code:

<?php
--------------Section NAME-----------------------------------
Dynamic URLs are rewritten as static
function Url_rewrite ($buffer)
{
return $buffer;
$search = Array (
'. php ',
'?',
' & ',
' Fileszz ',
'=',
' Hrefq ',
);
$replace = Array (
'. Files ',
'/',
' ZZ ',
' Files/zz ',
' Q ',
' Href= ',
);
Preg_match_all ('/href= "\/(index|error|cat|area|info|topic| post|profile|userinfo|cert| revise|review|feeback| KEYRANK|RSS) \.php (. *?) " /', $buffer, $match);
$url = Str_replace ($search, $replace, $match [0]);
$url = Preg_replace ('/\.files (. +?) (#.+?)?" $/', '. files\\1.html\\2 ', $url);
return Str_replace ($match [0], $url, $buffer);
}
?>

The function definition above is placed in the public header file. Then, add the following code at the beginning of the page where you want to optimize:

Ob_start ("Url_rewrite");

This is the only place where the original program needs to be modified. There is another problem with this. For example, I write pagination functions such as code, all require the original dynamic URL, and optimized later through the $_server[' php_self '. $_server[' query_string '] can only be optimized after static URLs, all dependent on the dynamic URL code must be modified to be able to handle the original URL and optimization. This has to overwrite many of the common header file's code. So I thought of a roundabout way:

<?php
--------------Section NAME-----------------------------------
Revert to dynamic URL
function Url_resume ($url)
{
$search = Array (
'. Files ',
'. php/',
' ZZ ',
'/zz ',
' Q ',
'. html ',
);
$replace = Array (
'. php ',
'. php? ',
' & ',
'?& ',
'=',
'',
);
$url = Str_replace ($search, $replace, $url);
return $url;
}
?>

With the above function, you can call a dynamic URL wherever you want it, without rewriting the core functions. It should be noted that Url_rewrite and Url_resume are the opposite processes, but their parameters are different. The former argument is the entire buffer, which is just a single URL, because the recovery is rare, and global processing overrides can improve speed.
