    $str = trim($str); //清除字符串两边的空格
    $str = strip_tags($str,""); //利用php自带的函数清除html格式
    $str = preg_replace("/	/","",$str); //使用正则表达式替换内容,如:空格,换行,并将替换为空。
    $str = preg_replace("/

    $str = preg_replace("/ /","",$str);
    $str = preg_replace("/  /","",$str);  //匹配html中的空格
    $str = preg_replace('# #','',$str);
    $str = preg_replace('/s+/u', '',$str);
    $str = preg_replace("/[sv".chr(163).chr(160)."]+$/","",$str);
    $str = str_replace(array(" "," ","	","
","
"," "), '', $str);
    $str = str_replace(chr(194) . chr(160), "-", $str);
    return trim($str); //返回字符串
}
