PHP文本编辑器如何与数据库连接

输出的那页只写了一句
<?php
echo $_POST['content'];
?>
上一页的表单是
<FORM method="POST" name="myform" action="echo.php">
<TABLE border="0" cellpadding="2" cellspacing="1">
<TR>
<TD>内容1：</TD>
<TD>
<INPUT type="hidden" name="content" value="<p> - 单个编辑器调用例子</p><p> </p><p align=center><b><font color=#ff0000>此样式为系统自带样式(s_mini)，最佳调用宽度为550px，高度350px！</font></b><br><br>(全部功能按钮，全菜单)</p><BR><P align=center>很不错的一个哦,ClearWind友情提示~!</P>">
<IFRAME ID="eWebEditor1" src="ewebeditor.html" frameborder="0" scrolling="no" width="550" height="350"></IFRAME>
