PHP实现gzip页面压缩方法_[PHP教程] 示例一(用php的内置压缩函数):
if(Extension_Loaded(’zlib’)) Ob_Start(’ob_gzhandler’); Header("Content-type: text/html"); ?>
无标题文档 for($i=0;$i<10000;$i++){ echo ’Hello World!’; } ?> if(Extension_Loaded(’zlib’)) Ob_End_Flush(); ?>
示例二(自写函数):
无标题文档
ob_end_flush(); //压缩函数 function ob_gzip($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; } ?>
