PHP - 遍历文件夹并显示HTML内容 [英] PHP - Iterate through folders and display HTML contents

问题描述

我目前正在尝试开发一种方法来概述我多年来创建和（合法）下载的所有不同的网页模板。我想要显示它们像 WordPress 正在使用一个小预览窗口预览其模板，显示混凝土包含样式和所有内容的文件。

I'm currently trying to develop a method to get a overview of all my different web templates I've created and (legally) downloaded over the years. I thought about displaying them like WordPress is previewing its templates with a small preview window, displaying the concrete file with styles and everything.

如何将它们分成行和列并创建 Ajax 模式窗口打开预览和分页等等？

How do I divide them into rows and columns and create Ajax modal window open on preview and pagination and so on?

我相信我可以管理，但是它是概念本身关于迭代几个文件夹然后找到所有 index.htm 和 index.html 页面并显示他们。

I believe I can manage, but it is the concept itself about iterating over several folders and then finding all index.htm and index.html pages and displaying them.

我对PHP中的目录并没有太多工作，到目前为止我发现的唯一引用和代码树桩只是列出了所有文件。某个目录，比如它包含的内容。

I've not worked very much with directories in PHP and the only references and code stumps I've found so far is just to list all the files in a certain directory like, what it contains.

是否有脚本，函数，代码段或只是一些信息来创建这样一个（可能是简单的）previ ew函数？

Is there a script, a function, snippet or just some information to create such a (probably simple) preview function?

推荐答案

glob（'*。html'）将如果他们都在一个目录中工作。

glob('*.html') will work if they're all in one directory.

如果你想走一个文件树 - 检查当前目录和子目录（子目录）子目录和子目录中的所有内容 - 那么你有几个选项。

If you want to walk a file tree -- checking everything in the current directory and in subdirectories and subdirectories of subdirectories (etc) -- then you have a couple of options.

一种方法是使用unix find 命令和PHP系统调用方法之一。类似于：

One would be to use the unix find command with one of the methods of PHP system invocation. Something like:

find< search_root_dir> -name* .html-print

find <search_root_dir> -name "*.html" -print

将获得类似于

search_root_dir/blah.html
search_root_dir/foo.html
search_root_dir/subdir/baz.html
search_root_dir/subdir/bah.html
...

你能做的另一件事就是编写一个使用 chdir 和 readdir 或者 scandir ，类似于：

Another thing you could do is write a recursive function that uses chdir and readdir or maybe scandir, something like:

function dir_walk($start_dir,$func) {
    $entries = scandir($start_dir);
    foreach($entries as $entry) {
        if($entry == '.' || $entry == '..') {
            /*skip these*/
        } else if(is_dir($entry)) {
            dir_walk($start_dir.'/'.$entry,$func);
        } else $func($start_dir.'/'.$entry);
    }
}

然后，写下另一个函数：

Then, write another function:

$html_files = array();
function record_html_files($filename) {
   global $html_files;
   if(strpos($filename,'*.html') === (strlen($filename) - 6))
     $html_files[] = $filename;
}

并将其称为：

dir_walk('/path/to/search/root','record_html_files');

或者，写dir_walk以便它接受一个带有方法调用的对象。这里有一些变化。

Or, write dir_walk so it accepts an object with a method call you can make inside. There's some variations possible here.
