php＋dbfile开发小型留言本

board.php用来存储数据，可以先在里面添加了一条留言纪录。

代码
<?php $Board=array(array(1081410332,'测试','测试留言本','http://www.piscdong.com'));?>

index.php是留言显示和提交页面。

代码
<?phprequire_once ('board.php');function htmlencode($content){$content=htmlspecialchars($content);$content=preg_replace("/\r/i","<br />",$content);return $content;}if($HTTP_SERVER_VARS['REQUEST_METHOD']=='POST'){$configpath_parts1 = pathinfo($SCRIPT_FILENAME);$time=time();$name=$HTTP_POST_VARS['name'];$url=(preg_match("/^[\\w-]+(\\.[\\w-]+)*@[\\w-]+(\\.[\\w-]+)+$/i",$HTTP_POST_VARS['url']) || $HTTP_POST_VARS['url']=='')?$HTTP_POST_VARS['url']:'http://'.htmlspecialchars(preg_replace("/https?\:\/\//i",'',$HTTP_POST_VARS['url']),ENT_QUOTES);$info=htmlencode($HTTP_POST_VARS['info']);if($name!='' && $info!=''){$Board[]=array($time,$name,$info,$url);}for($i=0;$i<count>";$filename=$configpath_parts1['dirname'].'/'.'board.php';if(is_writable($filename) || !file_exists($filename)){if(!$handle=fopen($filename,'w')){return false;}if(!fwrite($handle,$content)){return false;}fclose($handle);}else{return false;}header('Location:.');}else{?><title>留言本</title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <form method="post" name="form1" action=""><table border="0" cellspacing="5" cellpadding="0" align="center"> <tr><td><div style="overflow:auto;height:250px;border:1px dotted #999999;padding:5px;word-wrap:break-word;width:400px;"> <?php end($Board);for($i=0;$i<count($Board);$i++){$bd=current($Board);$s[]='<strong>'.($bd[3]!=''?'<a href="':'').(preg_match(" target="_blank':'').($bd[3]!=''?'">':'').$bd[1].($bd[3]!=''?'</a>':'').': '.$bd[2].'<br><em>-'.date("G:i, M j, Y",$bd[0]).'</em>';prev($Board);}echo join($s,'<br><br>');?></div></td></tr> <tr><td align="center"></td></tr> </table></form></count>
