壓縮HTML原始碼達到最小化HTML輸出，可以減少傳輸流量跟加速使用者接收。
function html_minify($buffer){
$replace = array(
\'//s\' => \'\',
\"/<\\?php/\" => \'
\"/\\n([\\S])/\" => \'$1\',
\"/\\r/\" => \'\',
\"/\\n/\" => \'\',
\"/\\t/\" => \'\',
\"/ +/\" => \' \',
);
if(strpos($buffer,\'\') !== false)
{
$replace = array(
\'//s\' => \'\',
\"/<\\?php/\" => \'
\"/\\r/\" => \'\',
\"/>\\n \'><\',
\"/>\\s+\\n \'><\',
\"/>\\n\\s+ \'><\',
);
}
$buffer = preg_replace(array_keys($replace), array_values($replace), $buffer);
return $buffer;
}
