Question

我刚才写了一些脚本，基本上搜索服务器上的指定文件夹并返回该文件夹中的图像列表。该目录是通过一个变量设置的，该变量根据您搜索的部分而改变。

但现在我需要修改它，以便搜索所有目录并列出各种目录中的图像。

这是我目前使用的脚本：

<?php
$dir = "assets/folder1/subfolder1/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if(stristr($file,$_POST['image_search'])){
                echo('<li><a href="/'.$dir . $file.'">'. $file .'</a></li>'."\n");
            }
        }
        closedir($dh);
    }
}
?>

搜索assets / folder1 /没问题，但我也有（folder1 / subfolder2，folder2 / subfolder1，folder2 / subfolder2 / etc等）

认为必须在目录等上进行某种通配符搜索，但真的很难思考它！

我认为像glob这样的东西可能会有所帮助，但不是很幸运

$dir = glob("/assets/*/*/");

Answer 1

据我所知，您需要迭代所有内容并检查是否is_dir()。我建议使用对象，例如：

$dir = new Folder('/');
$contents = $dir->find('*');
foreach ($contents as $content) {
    if (is_dir($content)) {
        //do something
    }
}

你也只能搜索某些目录，只需修复外卡。

Answer 2

如果我理解正确，您可以使用glob功能

$dir = '/path/to/directory/';
$files = glob( $dir."*.{jpg,gif,png}", GLOB_BRACE );
