Let me give you two examples of PHP using gzip for page compression. Gzip can compress js, css, image files, etc. The two simple examples introduced in this article are especially suitable for reference by beginners. Come and take a look.
Example 1, example of PHP built-in compression function
<?PHP
/**
* php 内置函数压缩
* bbs.it-home.org
*/
if(Extension_Loaded('zlib')) Ob_Start('ob_gzhandler');
Header("Content-type: text/html");
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>php程序员的笔记</title>
</head>
<body>
<?php
for($i=0;$i<10000;$i++){
echo 'Hello World!';
}
?>
</body>
</html>
<?PHP
if(Extension_Loaded('zlib')) Ob_End_Flush();
?>
Example 2, self-written function to achieve compression
<?php ob_start('ob_gzip'); ?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>自写函数压缩_bbs.it-home.org</title>
</head>
<body>
</body>
</html>
<?php
ob_end_flush();
//压缩函数
function ob_gzip($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;
}
?> |
