textarea中换行使用\r\n(ckeditor也是),可是却不能用str_replace()将\r\n进行处理,不知道为什么。

// textarea中换行采用\r\n,并且用str_replace方法不能搞掉!!
//test1表只有id、textarea两个字段,且只有id=1的一条记录。
require_once 'connect_text.php';
require_once 'show_message.php';
if($_POST['text']){
    $text = str_replace('\r\n', '', $_POST['text']);          //尝试搞掉,测试结果没有去掉\r\n
    $query="UPDATE test1 SET textarea = '$text' WHERE id = '1'";
    $result = mysql_query($query);
    if($result){
        echo "<script>alert('成了!')</script>";
    }
}
$query = "SELECT textarea FROM test1 WHERE id = '1'";
$result = mysql_query($query);
$row = mysql_fetch_array($result);
?>



//尝试搞掉,测试结果没有去掉\r\n
