大家知道,資料庫對於網路來說的重要性.由於cgi的複雜,現在asp和php+mysql已經成為主流.幾乎所有的個人網頁都要用到留言本,可是申請的留言本很不穩定.這為網上的交流帶來了諸多不便.所以,希望擁有自己的留言本的朋友越來越多.
但是,免費的個人首頁支援asp和php的很少.筆者現在向您推薦奧索網,(http://www.oso.com.cn)支援php.這樣您便有了能夠擁有自己留言本的基礎.現在,我就通過一個文本留言本的例子來講述php的簡單使用.
首先,我們先確定,留言的幾個過程:寫留言,發送,查看.(搜尋)等等.而且對於斑竹來說,管理留言本又是不可或缺的.這樣我們就不妨定位於6個php檔案,1個文字檔.6個php檔案分別為:guest.php manage.php reply.php sys.php del.php edit.php,1個文字檔為:guest.txt
先來看看guest.php的內容,你當然可以直接將下面的內容放到您的php網頁裡,請尊重作者的勞動,謝謝.

//guest.php:<?

require("sys.php");
if ($B1)
{
if ($message=="" or $name=="")
{
$errorm="<font color=red>出錯了!!!</font>姓名和留言內容必填";
}
else
{
#寫入資料
$space = " ";
$time = date(Y年m月d日H小時i分);
$ip=$REMOTE_ADDR;
$name=encode($name);
$homepage=encode($homepage);
$from=encode($from);
$email=encode($email);
$message=StripSlashes($message);
$message=htmlspecialchars($message);
$message=check_strlen_long($message);
$message=nl2br($message);
$guestcontent = "<tr><td><font color=#AB00E1>留言內容:</font><br><!--content>$message<!--endcontent> ";
$guestcontent=$guestcontent."<br><font color=#6633FF>留言人大名:</font><!--name>$name<!--endname> ";
if ($email !="")
{$guestcontent=$guestcontent."<br><font color=#9900CC>電子信箱</font><a href=\"mailto:$email\"><!--email>$email<!--endemail></a>"."$space";}
if ($homepage !="http://")
