自动发布新闻的php代码

WBOYOriginal: 2016-06-02 09:14:351534browse

新闻文件以文本文件.txt的格式存放在一个固定的目录下，新闻的发布可以自动完成,该过程由两部分组成: 第一是新闻的显示，由shownews.php脚本实现，代码如下：

<table border="0" width="90%">  
<?php
//在新闻文件中的第一行放新闻的标题
//新闻文件必须是文本文件(.txt)
$newspath = "./news/"; // 修改新闻文件存放的目录
$newsfile = array();
$hd = dir($newspath);
while ($filename = $hd->read()) {
    $s = strtolower($filename);
    if (strstr($s, ".txt")) {
        $lastchanged = filemtime($newspath . $filename);
        $newsfile[$filename] = $lastchanged;
    }
}
arsort($newsfile);
for (reset($newsfile); $key = key($newsfile); next($newsfile)) {
    print "<tr><td>n";
    $fa = file($newspath . $key);
    $s = trim($fa[0]);
    $s = htmlspecialchars($s);
    $lk = strlen($key);
    $a = substr($key, 0, $lk - 4);
    $s = "<a href=" . /pubnews . php ? id = ".$a."" target=_blank>" . $s . "</a>";
    print $s . " n";
    print "(" . date("Y年m月d日 - H:i:s", $newsfile[$key]) . ") 
n";
    print "</td></tr>";
}
$hd->close();
?>  
</table> 
在显示新闻的地方放入代码：
<?php
require "./shownews.php";
第二部分为新闻的发布，由pupnews . php脚本实现，代码如下： < ? phpif ($id == "") {
    Header("Location: ./shownews.php");
}
?>  
<html>  
<head>  
<meta content="chenqiang" name=Author>  
<?php
$filename = "./news/" . $id . ".txt";
$fa = file($filename);
$n = count($fa);
$s = trim($fa[0]);
$s = htmlspecialchars($s);
$t = " - news by waterwall";
print "<title>" . $s . $t . "</title>n";
?>  
</head>  
<body>  
<?php
//输出文本标题
print "<blockquote>n";
print "<b><center>" . $s . "n";
print "</center></b> 
<p>n";
//输出文本正文
for ($i = 1; $i < $n; $i+= 1) {
    $s = chop($fa[$i]);
    $s = htmlspecialchars($s);
    $s = trim($s);
    print " " . $s . " 
n";
}
print "</p></blockquote>n";
?>  
</body>  
</html>

用数据库也可实现，这只是文件形式的实现方式。
