如何像谷歌页面速度一样缩小我的 php 页面 html 输出？

例子：

<!DOCTYPE html>
<html>

<head>
<title>Untitled Document</title>

<meta name="description" content="Phasellus rhoncus euismod libero a lacinia. Lorem ipsum dolor sit amet, consectetur adipiscing elit." />

</head>

<body>
<div id="content">
<div id="post-1">
<h1>Phasellus rhoncus euismod libero a lacinia.</h1>
<p>...</p>
</div>

<div id="post-2">
<h1>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</h1>
<p>...</p>
</div>

</div>


</body>
</html>

使用 php ob_start，这个 html 输出怎么会变成这样？

<!DOCTYPE html>
<html>
<head>
<title>Untitled Document</title> 
<meta name="description" content="Phasellus rhoncus euismod libero a lacinia. Lorem ipsum dolor sit amet, consectetur adipiscing elit." />
</head>
<body>
<div id="content">
<div id="post-1">
<h1>Phasellus rhoncus euismod libero a lacinia.</h1>
<p>...</p>
</div>
<div id="post-2">
<h1>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</h1>
<p>...</p>
</div>
</div>
</body>
</html>

编辑：

我已经尝试过这段代码（基于 James Pegg 的回答）

function sanitize_output($buffer){
$search = array("\n", "\t");
return preg_replace($search, '', $buffer);}

ob_start("sanitize_output");

但它不起作用。该页面现在是空的。

最终工作代码（基于 W. Kristianto 的回答）：

function sanitize_output($buffer){
$buffer = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $buffer);
return $buffer;}

只需删除仅包含\r\n, or \r, or的每一行\n。

这很有用：如何从 PHP 中的文本中删除空行？

您可以像这样取出所有新行和标签：

<?php
// Start Output Bugger
ob_start();

// Start HTML Output
?>
<!DOCTYPE html>
<html>

<head>
<title>Untitled Document</title>

<meta name="description" content="Phasellus rhoncus euismod libero a lacinia. Lorem ipsum dolor sit amet, consectetur adipiscing elit." />

</head>

<body>
<div id="content">
<div id="post-1">
<h1>Phasellus rhoncus euismod libero a lacinia.</h1>
<p>...</p>
</div>

<div id="post-2">
<h1>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</h1>
<p>...</p>
</div>

</div>


</body>
</html>

<?php

// Save Output bugger as a variable
$html = ob_get_clean();

//Array of characters to replace
$strings = Array("\n", "\t");

//Strip out new lines and tabs
$html = str_replace($strings, '', $html);

//Echo minified content
echo $html;
?>

希望有帮助！
