"Go" apache/php turn on gzip compression

1. Open PHP Mode

Principle:

Header ("Content-encoding:gzip"); Echo gzencode (' Songjiankang ');

Example 1:

function Ob_gzip ($content)//$content is the content of the page to be compressed, or the cookie raw material {    if (! headers_sent () &&     //If the page header information is not output    extension_loaded ("zlib") &&     //and zlib extension has been loaded into PHP    strstr ($_server["http_accept_encoding"], " GZIP)     //And the browser says it can accept gzip page    {        $content = Gzencode ($content. "\n//This page has been compressed", 9); This page has been compressed "comment label, and then use the Gzencode () function provided by zlib to perform a level 9 compression, the parameter value range is 0-9,0 means no compression, 9 is the maximum compression, of course, the higher the compression the more CPU.                                                                          //Then use the header () function to send some header information to the browser, telling the browser that this page has been compressed with gzip!        header ("Content-encoding:gzip");        Header ("vary:accept-encoding");        Header ("Content-length:".) Strlen ($content));    }    return $content; Return the compressed content, or send the compressed cookie back to the workbench. }ob_start (' Ob_gzip ');

Example 2:

#ob_gzhandler for PHP built-in functions, refer to Manual Ob_start (' Ob_gzhandler ');

2, Apache Way to open:

A. Open the module:

LoadModule deflate_module modules/mod_deflate.soloadmodule headers_module modules/mod_headers.so

Increase in b.httpd.conf

<ifmodule deflate_module> deflatecompressionlevel 9 addoutputfilterbytype deflate text/html Text/plain text/xml A Pplication/json application/xml addoutputfilter DEFLATE js css addoutputfilter includes. shtml. htm. Xml. php. html</ Ifmodule>

C. Restart the server
