php 取除连续空格与换行代码，这些我们都用到str_replace与正则函数
第一种：
$content=str_replace("n","",$content);
echo $content;
第二种：
$content=preg_replace("/s/","",$content);
echo $content;
$str="i am a booknnnnnmoth";
//去除所有的空格和换行符
echo preg_replace("/[s]{2,}/","",$str).'
';
//去除多余的空格和换行符，只保留一个
echo preg_replace("/([s]{2,})/","\1",$str);
?>
