PHP實作壓縮html的函數

function compress_html($string) {
    $string = str_replace("rn", '', $string); //清除换行符
    $string = str_replace("n", '', $string); //清除换行符
    $string = str_replace("t", '', $string); //清除制表符
    $pattern = array (
                    "/> *([^ ]*) *                    "/[s] /",
                    "//",
                    "/" /",
                    "/ "/",
                    "'/*[^*]**/'"
                    );
    $replace = array (
                    "><",
                    " ",
                    "",
                    """,
                    """,
                    ""
                    );
    return preg_replace($pattern, $replace, $string);
}
