2016年9月15日

phpコード:
<?php

ob_start(“ob_gzhandler");
ob_start(“compress");

header(“Content-type: text/Css; charset: UTF-8");
header(“Cache-Control: must-revalidate");
$off = 0; # Set to a reaonable value later, say 3600 (1 hr);
$exp = “Expires: " . gmdate(“D, d M Y H:i:s", time() + $off) . " GMT";

header($exp);

function compress($buffer) {
$buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!’, ", $buffer); // remove comments
$buffer = str_replace(array(“\r\n", “\r", “\n", “\t", ' ', ' ', ' '), ", $buffer); // remove tabs, spaces, newlines, etc.
$buffer = str_replace('{ ', '{', $buffer); // remove unnecessary spaces.
$buffer = str_replace(' }’, '}’, $buffer);
$buffer = str_replace('; ', ';’, $buffer);
$buffer = str_replace(', ', ',’, $buffer);
$buffer = str_replace(' {', '{', $buffer);
$buffer = str_replace('} ', '}’, $buffer);
$buffer = str_replace(': ', ':’, $buffer);
$buffer = str_replace(' ,’, ',’, $buffer);
$buffer = str_replace(' ;’, ';’, $buffer);
return $buffer;
}

require_once('screen.css’);
require_once('layout.css’);
require_once('custom.php’);
require_once('titles.css’);
require_once('cuo.css’);
