多维数组php平面文件

Question

我正在升级我的网站运行方式，我已经在页面中集成了 mant php 脚本，但我正在尝试开发完全基于 php 的网站，例如，而不是加载 url：

url/events/event-1
url/events/event-2

^^^ 2 个单独的页面

我正在尝试加载

url/event?url=event-1

这样我可以更新 1 个页面，但根据

加载不同的内容

$_GET['url']

参数.....

到目前为止我所拥有的......

我加载 url/event?url=dance

它会自动在目录中搜索文件名“dance.txt”

如果文件不存在，则转发到主事件页面（url/events）

如果文件确实存在，它会创建一个关于事件的单行字符串......

文件内容如下：

Dance::::18-02-2012::::http://{external link}::::Event Information

我为导入这些数据并显示它而开发的脚本，工作正常，但我需要一个页面，将所有事件加载到一个单独的 div 中......

如果我能弄清楚如何将事件数组数据排列成所有事件的多维数组，那么制作这个页面就足够简单了......

对于单个事件，脚本简单地将变量定义为：

$name, $date, $link, $writeup

我附上了我如何做到这一点的示例代码...

    $dir    = '/server/htdocs/data/';     // path to dir with all event txt files in
$files = scandir($dir);

$fruit = array_shift($files);

$fruit2 = array_shift($files);    // array shifts remove values of '.' and '..'

$line = implode(" ",$files);    // back into string for str_replace

// echo $line;

$oldword = ".txt";

$newword = "";

$newline = str_replace($oldword, $newword, $line);

// echo $newline;


$files = explode(" ", $newline); // array of filenames

if (in_array($url, $files)) {
  $contents = file_get_contents('data/'.$url.'.txt');
} else { header('Location: http://{url}/events'); }

$info = explode('::::', $contents);

// print_r($info);

$name = $info[0];

$date = $info[1];

$link = $info[2];

$writeup = $info[3];

这对单个页面非常有效，但是，我需要一个这样的数组：

$events = array ( array ( Name => event-1,
                          Date => date-1,
                          Link => link-1,
                          Writeup => event-info ),

                  array ( Name => event-2,
                          Date => date-2,
                          Link => link-2,
                          Writeup => event-info ),

                  array ( Name => event-3,
                          Date => date-3,
                          Link => link-3,
                          Writeup => event-info )
                        );

这就是我假设数组的形成方式，但我需要脚本来计算 /data/ 文件夹中有多少文件，然后（我假设）有一个 foreach 循环，以便每个数组（事件）我可以回声：

<div id="content2"> 
                    <div class="post">
<center><h2><u>'.$name.' ('.$date.')</u></h2></center>
                       <p class="postmeta"></p>
                        <div class="entry">

<CENTER><img src="events/posters/'.$name.'.jpg" height="400" width="500"></center>

<p><p>

<p>'.$writeup.'</p>

<p><a href="'.$link.'" " target="_blank">'.$name.' Online</a></p>


 </div>
                    </div><!-- post --> 
                </div><!-- content2 -->

我知道这似乎是一种复杂的处理方式，但这样我的网站将可以通过 txt 文件中的数据 100% 编辑，因为现在我必须克隆现有页面，然后重新写入其中的所有内容参加新活动！

foreach($files as $key => $value) {

$array[] = array(explode('::::',(file_get_contents('data/'.$files[$key].'.txt'))));

}

print_r($array);

啊哈几乎完成了。

ps 我希望 foreach 按每个 txt 文件中规定的日期列出，它目前按文件名的字母顺序列出...

Answer 1

借用了一点 Jribeiro 的代码，将文件实际读入二维数组。

$items = array();
if ($handle = opendir($dir)) {
    while (false !== ($file = readdir($handle))) {
        $fp = fopen("$file","r");

        while($line = fgets($fp)){
            $parts = explode("::::",$line);
            $newArr["Name"] = $parts[0];
            $newArr["Date"] = $parts[1];
            $newArr["Link"] = $parts[2];
            $newArr["Writeup"] = $parts[3];
            $items[] = $newArr;  // add newArr to items
        }
        fclose($fp);
    }
    closedir($handle);
}

print_r($items);

然后，循环遍历$items 数组：

foreach($items as $item){
    $name = $item["Name"];
    echo "Name is $name<br>";
    // etc
}

不过，我需要通知您考虑使用 MySQL 来执行此操作，因为它比使用纯文本文件更容易、更安全且更强大。

如果你想要 dir 中的文件数，你可以试试这个：

function fileCounter($dir){
    $counter = 0;
    if ($handle = opendir($dir)) {
      //echo "Directory handle: $handle\n";
      //echo "Files:\n";
      /* This is the correct way to loop over the directory. */
      while (false !== ($file = readdir($handle))) {
          //echo "<BR>".$counter." - $file";
          $counter++;
      }
      closedir($handle);
    }
    $counter -= 1; // in order to exclude '.' and '..', as well as start the counter on 1
    return $counter;
}

我实际上不太确定我是否正确理解了您的问题。 但最后你想将嵌套数组$events 存储在平面文件中并将其读回数组？ 我建议使用serialize 来做到这一点，那么它很简单：

$events = array ( array ( Name => event-1,
                          Date => date-1,
                          Link => link-1,
                          Writeup => event-info ),

                  array ( Name => event-2,
                          Date => date-2,
                          Link => link-2,
                          Writeup => event-info ),

                  array ( Name => event-3,
                          Date => date-3,
                          Link => link-3,
                          Writeup => event-info )
                        );
file_put_contents("/foo/bar",serialize($events)); // BAM, it's in the file :)
//reading it back is equally simple
$events2 = unserialize(file_get_contents("/foo/bar"));
