纯代码实现WordPress前端html代码压缩优化
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; }
