以下代码是扔在module.php里面的

<?php

//网站压缩

function sl_ys($buffer){

    $initial=strlen($buffer);

    $buffer=explode("<!--em-compress-html-->", $buffer);

    $count=count ($buffer);

    for ($i = 0; $i <= $count; $i++){

        if (stristr($buffer[$i], '<!--em-compress-html no compression-->')){

            $buffer[$i]=(str_replace("<!--em-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;

}

?> 

以下代码是扔在footer.php最末尾(即结尾处)

<?php

        $html=ob_get_contents();

        ob_get_clean();

        echo sl_ys($html);

?>
