Question

我尝试编辑这个PHP代码来指定一个目录，用于递归列出文件和子目录但没有快乐。

非常感谢任何想法。

我刚从这个链接找到了这段代码：

以下是以下代码：

    <?php

    /**
    * Recovers folder structure and files of a certain path
    * 
    * @param string $path Folder where files are located
    * @param string $pattern Filter by extension
    * @param string $flags Flags to be passed to the glob
    * @return array Folder structure
    */


    function getFolderTree($path)
    {
    //Recovers files and directories
    //$paths = glob($path  . "*", GLOB_MARK | GLOB_ONLYDIR | GLOB_NOSORT);
//@param string ($path ".\temp" );
//$path = ".";

    $paths = glob($path . "*",  GLOB_MARK | GLOB_ONLYDIR | GLOB_NOSORT);
    $files = glob($path . "*");


    //Traverses the directories found
    foreach ($paths as $key => $path)
    {
    //Create directory if exists
    //$directory = explode("//", $path);
    $directory = explode("\\", $path);
    unset($directory[count($directory) - 1]);
    $directories[end($directory)] = getFolderTree($path);

    //Verify if exists files
    foreach ($files as $file)
    {
        if (strpos(substr($file, 2), ".") !== false)
            $directories[] = substr($file, (strrpos($file, "\\") + 1));
    }
    }

    //Return the directories
    if (isset($directories))
    {
    return $directories;
    }
    //Returns the last level of folder
    else
    {
    $files2return = Array();
    foreach ($files as $key => $file)
        $files2return[] = substr($file, (strrpos($file, "\\") + 1));
    return $files2return;
    }
    }

    /**
    * Creates the HTML for the tree
    * 
    * @param array $directory Array containing the folder structure
    * @return string HTML
    */
    function createTree($directory)
    {
    $html = "<ul>";
    foreach($directory as $keyDirectory => $eachDirectory)
    {
    if(is_array($eachDirectory))
    {
        $html .= "<li class='closed'><span class='folder'>" . $keyDirectory .  "</span>";
        $html .= createTree($eachDirectory);
        $html .=  "</li>";
    }
    else
    {
        $html .= "<li><span class='file'>" . $eachDirectory . "</span></li>";
    }
    }
    $html .= "</ul>";

    return $html;
    }

    //Create output

    $pathx = 'temp/';
    //$directory = getFolderTree($pathx);
    $directory = getFolderTree($pathx );

    $htmlTree = createTree($directory[$pathx]);
    ?>

Answer 1

您的代码中存在两个问题。

第一个是目录分隔符 - 您应该使用常量DIRECTORY_SEPARATOR而不是\，例如：

$directory = explode(DIRECTORY_SEPARATOR, $path);

这将使您的代码不仅在Windows上有效，而且在unix系统上也有效。

第二个问题在这里：

$htmlTree = createTree($directory[$pathx]);

$pathx数组中没有键$directory。可能它应该是这样的：

$htmlTree = createTree($directory);

但请注意，很难说出你期望的结果以及你得到的错误。
