As you know, the database is of great importance to the network. Because of the complexity of CGI, now the ASP and Php+mysql have become mainstream. Almost all of the personal web pages have to use the message book, but the application of the message is very unstable. This brings a lot of inconvenience to online communication. Want to have their own message book more and more friends.
However, the free personal homepage supports very few ASP and PHP. I now recommend to you Osso network, (http://www.oso.com.cn) support PHP. So you have the basis to have your own message book. Now, I will use the example of a text message to describe the simple usage of PHP.
First of all, we first determine, the message of a few processes: write a message, send, view. (search) and so on. And for the owner, management message is also indispensable. So we can locate 6 php files, 1 text files. 6 php files are: guest.php manage.php reply.php sys.php del.php edit.php,1 a text file is: guest.txt
First look at the content of guest.php, you can certainly directly put the following content into your PHP page, please respect the author's labor, thank you.
----------------------
guest.php:<?
Require ("sys.php");
if ($B 1)
{
if ($message = = "" or $name = = "")
{
$errorm = "<font color=red> was wrong!!! </font> name and message content must be filled ";
}
Else
{
#写入数据
$space = "";
$time = Date (Y-year m-month D-day H I-hour);
$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);
$guestcontent = "<tr><td><font color= #AB00E1 > Message content:</font><br><!--content>$ message<!--endcontent> ";
$guestcontent = $guestcontent. " <br><font color= #6633FF > Message:</font><!--name> $name <!--endname> ";
if ($email!= "")
{$guestcontent = $guestcontent. " <br><font color= #9900CC > Email </font><a href=\ "mailto: $email \" ><!--email> $email <! --endemail></a> "." $space ";}

{$guestcontent = $guestcontent. " <font color= #9900CC > Home:</font> $hompage <a href=\ "$homepage \" ><!--homepage> $homepage <!- -endhomepage></a> ";}
$guestcontent = $guestcontent. " <br><font color= #0000FF > Time: $time from:<!--from> $from <!--endfrom> $ip </font> ";
$guestcontent =ereg_replace (CHR), "", $guestcontent);
$guestcontent = $guestcontent. " $FP =fopen ($guestfile, "a");
Fputs ($fp, $guestcontent);
Fclose ($FP);
