textarea空格问题，进者有分

$Text=ereg_replace(" "," ",$Text);
$Text//是你的textarea

读出来时，加上htmlspecialchars（变量名）就可以了

呵呵，挺热闹啊，那大家看看这个函数
<?
function ubb($tmpmsg) {
//        $tmpmsg =str_replace('<','<',$tmpmsg);
//        $tmpmsg =str_replace('>','>',$tmpmsg);
        $tmpmsg=htmlspecialchars($tmpmsg);
        $tmpmsg=nl2br($tmpmsg);
        //$tmpmsg =str_replace('',' ',$tmpmsg);
        $tmpmsg =str_replace('&','&',$tmpmsg);
        $tmpmsg =str_replace("","<u>",$tmpmsg);
        $tmpmsg =str_replace("","</u>",$tmpmsg);
        $tmpmsg =str_replace("","<b>",$tmpmsg);
        $tmpmsg =str_replace("","</b>",$tmpmsg);
        $tmpmsg =str_replace("","<i>",$tmpmsg);
        $tmpmsg =str_replace("","</i>",$tmpmsg);
        $tmpmsg =str_replace("[br]","<br>",$tmpmsg);
        $tmpmsg =str_replace("[list]","<ul>",$tmpmsg);
        $tmpmsg =str_replace("[/list]","</ul>",$tmpmsg);
        $tmpmsg =str_replace("[olist]","<ol>",$tmpmsg);
        $tmpmsg =str_replace("[/olist]","</ol>",$tmpmsg);
        $tmpmsg =str_replace("[*]","<li>",$tmpmsg);
        $tmpmsg =str_replace("[hr]","<hr width=40% align=left>",$tmpmsg);
        $tmpmsg =str_replace("[sup]","<sup>",$tmpmsg);
        $tmpmsg =str_replace("[/sup]","</sup>",$tmpmsg);
        $tmpmsg =str_replace('[url="','[url="',$tmpmsg);
        $tmpmsg =str_replace('"]','"]',$tmpmsg);        $pattern = array(
        "/\[font=([^\[]*)\](.+?)\[\/font\]/is",
        "/\[color=([#0-9a-z]{1,10})\](.+?)\[\/color\]/is",

        "/(\[glow=)(\S+?)(\,)(.+?)(\,)(.+?)(\])(.+?)(\[\/glow\])/is",
        "/\[code\](.+?)\[\/code\]/is");        $replacement = array(

            $tmpmsg = eregi_replace("\\[size=([^\\[]*)\\]","<font size=\\1>",$tmpmsg);
            $tmpmsg = str_replace("[/size]","</font>",$tmpmsg);        return $tmpmsg;
}
?>

然后我从数据库读出数据的时候用这个函数
例如：
<?
include("inc/conn.php");
include("inc/function.php");//其中有ubb函数
$sql="select id,body from news where id='$id' order by id";
$result=mysql_query($sql);
if($myrow=mysql_fetch_array($result))
  {
          $id=$myrow["id"];
          $body=ubb($myrow["body"]);
echo "$body";
}
?>
这样怎么不可以显示空格呢？

$body=str_replace(" ", " ", $myrow["body"]);

楼上的方法没有做好。抗议楼上们，你们都说光了，我还说什么？不过你们漏了一点。嘿嘿。 ice_berg16(寻梦的稻草人) 的替换nbsp的方法解决不了问题。因为在html显示里，超过两个nbsp的空格代码就会自动忽略，显示不出来。呵呵。所以还是要替换成全角空格才行。楼主，你上面说显示不出来空格，给你个方法吧：
$body=str_replace(" ","　", $myrow["body"]);注意，第一个是两个半角空格，就是常用的空格。第二个是一个全角空格。这样就能工整显示了。

用 htmlspecial($_POST['textareaName']) 取值就OK了

不好意思~~~~~`应该是 htmlspecialchars($_POST['textareaName']) 上面函数中少了chars *^_^*

htmlspecialchars这样不行吧？如果有多个空格，就会最多只显示两个的。
