htaccess PHP+htaccess implements GZIP compression and transmission of static HTML files throughout the site

The power of apache finally exceeded my imagination. I just scratched the surface of php, and this surface exploded on the basis of my original knowledge base, like the "avalanche breakdown" of the PN junction, which made me think It combines a variety of technologies with unlimited application prospects.
Since Kyushu’s future servers limit traffic, reducing traffic load can also reduce money expenditures.
The most convenient way to reduce traffic is to use Gzip compression. The gzip compression of apache is accomplished by a class library called zlib and the gzip module (mod_gzip.c). This thing has been researched by a group of experts, because gzip itself It is well-known and has open source compression principles with high compression rates, so our open source apache uses this open source compression technology.
Well, this .htaccess is also a powerful tool for apache. It is so powerful. It also depends on what modules your apache has installed to determine what you can write in this file. For example, if you have installed the URL rewriting module (Module mod_rewrite. c), you can write some URL rewriting code to implement your file rewriting.
Knowledge dissemination completed. . . .
Let’s get to the point.
How to make the real static html files of your whole site into gzip transmission?
For the convenience of understanding, I wrote a simple php program for everyone.
First we create an l.php using gzip compression algorithm, read xxx.html in the file and display it, and then rewrite xxx.html to 1.php in .htaccess. Keep it simple. Since our server considers .htaccess to have the highest priority, when accessing xxx.html, this static file is not accessed, but 1.php is accessed.
The following is my code: (read in index2.html, and then rewrite )
.htaccess:

Copy code The code is as follows:


# Turn on RewriteEngine mode
RewriteEngine On
RewriteBase /
RewriteRule index2.html l.php?fn=index2.html


1. php

Copy code The code is as follows:


   $phpver = phpversion(); 
   $useragent = (isset($_SERVER["HTTP_USER_AGENT"]) ) ? $_SERVER["HTTP_USER_AGENT"] : $HTTP_USER_AGENT; 
   if ( $phpver >= '4.0.4pl1' && ( strstr($useragent,'compatible') || strstr($useragent,'Gecko') ) ) 
   { 
       if ( extension_loaded('zlib') ) 
       { 
           ob_start('ob_gzhandler'); 
       } 
   } 
   else if ( $phpver > '4.0' ) 
   { 
       if ( strstr($HTTP_SERVER_VARS['HTTP_ACCEPT_ENCODING'], 'gzip') ) 
       { 
           if ( extension_loaded('zlib') ) 
           { 
               $do_gzip_compress = TRUE; 
               ob_start(); 
               ob_implicit_flush(0); 
               header('Content-Encoding: gzip'); 
           } 
       } 
   } 
?> 
$rfile = addslashes(dirname(dirname(__FILE__))).'/'.'./httpdocs/'.$_REQUEST['fn']; 
echo READ_FILE_CONTENTS($rfile); 
function READ_FILE_CONTENTS($file) 

   if(!function_exists("file_get_contents"))return file_get_contents($file); 
   $ifile = fopen($file,"r"); 
   $contents = false; 
   if($ifile) while (!feof($ifile)) $contents .= fgets($ifile); 
   fclose($ifile); 
   return $contents; 

?> 
// Compress buffered output if required and send to browser 
if ( $do_gzip_compress ) 

   // 
   // Borrowed from php.net! 
   // 
   $gzip_contents = ob_get_contents(); 
   ob_end_clean(); 
   $gzip_size = strlen($gzip_contents); 
   $gzip_crc = crc32($gzip_contents); 
   $gzip_contents = gzcompress($gzip_contents, 9); 
   $gzip_contents = substr($gzip_contents, 0, strlen($gzip_contents) - 4); 
   echo "x1fx8bx08x00x00x00x00x00"; 
   echo $gzip_contents; 
   echo pack('V', $gzip_crc); 
   echo pack('V', $gzip_size); 

exit; 
?> 


实际上这个东西能用更好的方法解决,就是用这个
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /xxx/xxx.php [L]
但是我还没研究出来怎么处理这个%{REQUEST_FILENAME},还望高手赐教。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
