找到相关主题中的functions.php文件，把如下代码添加到文件中。（当然其他的php程序也是可以通过添加下面的代码实现相同功能）
function compressHtml($html_source) {
$chunks = preg_split('/(<!--<nocompress>-->.*?<!--<\/nocompress>-->|<nocompress>.*?<\/nocompress>|<pre.*?\/pre>|<textarea.*?\/textarea>|<script.*?\/script>)/msi', $html_source, -1, PREG_SPLIT_DELIM_CAPTURE);
$compress = '';
foreach ($chunks as $c) {
if (strtolower(substr($c, 0, 19)) == '<!--<nocompress>-->') {
$c = substr($c, 19, strlen($c) - 19 - 20);
$compress .= $c;
continue;
} else if (strtolower(substr($c, 0, 12)) == '<nocompress>') {
$c = substr($c, 12, strlen($c) - 12 - 13);
$compress .= $c;
continue;
} else if (strtolower(substr($c, 0, 4)) == '<pre' || strtolower(substr($c, 0, 9)) == '<textarea') {
$compress .= $c;
continue;
} else if (strtolower(substr($c, 0, 7)) == '<script' && strpos($c, '//') != false && (strpos($c, "\r") !== false || strpos($c, "\n") !== false)) {
$tmps = preg_split('/(\r|\n)/ms', $c, -1, PREG_SPLIT_NO_EMPTY);
$c = '';
foreach ($tmps as $tmp) {
if (strpos($tmp, '//') !== false) {
if (substr(trim($tmp), 0, 2) == '//') {
continue;
}
$chars = preg_split('//', $tmp, -1, PREG_SPLIT_NO_EMPTY);
$is_quot = $is_apos = false;
foreach ($chars as $key => $char) {
if ($char == '"' && $chars[$key - 1] != '\\' && !$is_apos) {
$is_quot = !$is_quot;
} else if ($char == '\'' && $chars[$key - 1] != '\\' && !$is_quot) {
$is_apos = !$is_apos;
} else if ($char == '/' && $chars[$key + 1] == '/' && !$is_quot && !$is_apos) {
$tmp = substr($tmp, 0, $key);
break;
}
}
}
$c .= $tmp;
}
}
$c = preg_replace('/[\\n\\r\\t]+/', ' ', $c);
$c = preg_replace('/\\s{2,}/', ' ', $c);
$c = preg_replace('/>\\s</', '> <', $c);
$c = preg_replace('/\\/\\*.*?\\*\\//i', '', $c);
$c = preg_replace('/<!--[^!]*-->/', '', $c);
$compress .= $c;
}
return $compress;
}
在相关主题中的header.php顶部添加如下代码
<?php ob_start(); ?>
在相关主题中的footer.php底部添加如下代码
<?php
$html_source = ob_get_contents();
ob_clean();
print compressHtml($html_source);
ob_end_flush();
?>
