示例一（用php的內置壓縮函數）：
| <?PHP if(Extension_Loaded('zlib')) Ob_Start('ob_gzhandler'); Header("Content-type: text/html"); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>無標題文檔</title> </head> <body> <?php for($i=0;$i<10000;$i++){ echo 'Hello World!'; } ?> </body> </html> <?PHP if(Extension_Loaded('zlib')) Ob_End_Flush(); ?> |
示例二（自寫函數）：
| <?php ob_start('ob_gzip'); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>無標題文檔</title> </head> <body> </body> </html> <?php ob_end_flush(); //壓縮函數 function ob_gzip($content){ if(!headers_sent()&&extension_loaded("zlib")&&strstr($_SERVER["HTTP_ACCEPT_ENCODING"],"gzip")){ $content = gzencode($content,9); header("Content-Encoding: gzip"); header("Vary: Accept-Encoding"); header("Content-Length: ".strlen($content)); } return $content; } ?> |
