纯代码实现WordPress前端html代码压缩优化，php代码如下：
/**
* 前端html代码压缩
**/
function wp_compress_html($buffer){
$initial=strlen($buffer);
$buffer=explode("<!--wp-compress-html-->", $buffer);
$count=count ($buffer);
for ($i = 0; $i <= $count; $i++){
if (stristr($buffer[$i], '<!--wp-compress-html no compression-->')){
$buffer[$i]=(str_replace("<!--wp-compress-html no compression-->", " ", $buffer[$i]));
}else{
$buffer[$i]=(str_replace("\t", " ", $buffer[$i]));
$buffer[$i]=(str_replace("\n\n", "\n", $buffer[$i]));
$buffer[$i]=(str_replace("\n", "", $buffer[$i]));
$buffer[$i]=(str_replace("\r", "", $buffer[$i]));
while (stristr($buffer[$i], ' '))
{
$buffer[$i]=(str_replace(" ", " ", $buffer[$i]));
}
}
$buffer_out.=$buffer[$i];
}
$final=strlen($buffer_out);
$savings=($initial-$final)/$initial*100;
$savings=round($savings, 2);
$buffer_out.="\n<!--压缩前的大小: $initial bytes; 压缩后的大小: $final bytes; 节约：$savings% -->";
return $buffer_out;
}
调用方法：在footer.php页末尾</html>标签后添加如下php代码：
$html=ob_get_contents(); ob_get_clean(); echo wp_compress_html($html);
排除文章内容中的高亮代码块：
function unCompress($content) {
if(preg_match_all('/(crayon-|<\/pre>)/i', $content, $matches)) {
$content = '<!--wp-compress-html--><!--wp-compress-html no compression-->'.$content;
$content.= '<!--wp-compress-html no compression--><!--wp-compress-html-->';
}
return $content;
}
