Php 扫描功能不工作

我正在尝试创建一个函数来扫描一个目录中的所有文件和该目录下的目录（稍后会更进一步）。目前，它在主（指定）目录中看到所有文件，但在该指定目录下的目录中，代码看不到所有文件

这是我的职责：

<?php
function scanfiles($arg1){
    // Set variables
    $files = array();

    // Analyze the main dir
    $main_files = array_filter(scandir($arg1), function($files_arg1){ return is_file($files_arg1); });
    $main_folders = array_filter(scandir($arg1), function($folders_arg1){ return is_dir($folders_arg1); });

    // Remove dots from main_folders
    $main_folders = array_diff($main_folders, array('..', '.'));

    // Add all files from main_files to the files array
    foreach($main_files as $main_key => $main_value){
        $files[] = "/" . $main_value;
    }

    // Check subfolders
    foreach($main_folders as $sub1_key => $sub1_value){
        // Analyze subfolder
        $sub1_files = array_filter(scandir($arg1 . "/" . $sub1_value), function($files_arg1){ return is_file($files_arg1); });
        $sub1_folders = array_filter(scandir($arg1 . "/" . $sub1_value), function($folders_arg1){ return is_dir($folders_arg1); });

        // Add all files from sub1_files to files array
        foreach($sub1_files as $sub1_add_key => $sub1_add_value){
            $files[] = "/" . $sub1_value . "/" . $sub1_add_value;
        }
    }
    return $files;
}

foreach (scanfiles(__DIR__) as $key => $value) {
    echo "<br>" . $value;
}
?>

我真的不明白出了什么问题，因为这应该是输出：

/.DS_Store
/.htaccess
/action.php
/index.php
/admin/.DS_Store
/admin/index.php
/admin/login.php
/includes/.DS_Store
/includes/.htaccess
/includes/config.inc.php
/install/index.php

有人知道问题出在哪里，能帮我吗

所有这些帮助都将不胜感激

用corrent answare编辑 它的原因是数组的过滤功能 您发送的路径不正确 如果您像这样更改代码

$sub1_files = array_filter(scandir($arg1 . "/" . $sub1_value.'/'),   function($files_arg1){
        echo $files_arg1;
        return is_file($files_arg1); });

你会注意到我说的话。你可以自己处理，也可以发送路径到array_filter

因此，我现在发现了问题，我在子文件夹的scandir中使用了$folders_arg1变量，但没有定义它应该检查子文件夹中是否有文件。因为它会在文件本身的文件夹中搜索

固定代码：

<?php
function scanfiles($arg1){
    global $sub1_value;

    // Define arg1 as a constant
    define("arg1", $arg1);

    // Set variables
    $files = array();

    // Analyze the main dir
    $main_files = array_filter(scandir($arg1), function($files_arg1){ return is_file(arg1 . "/" . $files_arg1); });
    $main_folders = array_filter(scandir($arg1), function($folders_arg1){ return is_dir(arg1 . "/" . $folders_arg1); });

    // Remove dots from main_folders
    $main_folders = array_diff($main_folders, array('..', '.'));

    // Add all files from main_files to the files array
    foreach($main_files as $main_key => $main_value){
        $files[] = "/" . $main_value;
    }

    // Check subfolders
    foreach($main_folders as $sub1_key => $sub1_value){
        // Analyze subfolder
        $sub1_files = array_filter(scandir($arg1 . "/" . $sub1_value), function($files_arg1){ return is_file(arg1 . "/" . $GLOBALS['sub1_value'] . "/" . $files_arg1); });
        $sub1_folders = array_filter(scandir($arg1 . "/" . $sub1_value), function($folders_arg1){ return is_dir(arg1 . "/" . $GLOBALS['sub1_value'] . "/" . $folders_arg1); });

        // Add all files from sub1_files to files array
        foreach($sub1_files as $sub1_add_key => $sub1_add_value){
            $files[] = "/" . $sub1_value . "/" . $sub1_add_value;
        }
    }
    return $files;
}
foreach (scanfiles(__DIR__) as $key => $value) {
    echo "<br>" . $value;
}
?>

嗯。。。。否如果您阅读注释，您会看到该注释被插入到最终将成为结果的数组中。如果没有斜杠，结果中的

/index.php

将是

index.php

。我已经更改了我的答案。你可以查看它

<?php
function scanfiles($arg1){
    global $sub1_value;

    // Define arg1 as a constant
    define("arg1", $arg1);

    // Set variables
    $files = array();

    // Analyze the main dir
    $main_files = array_filter(scandir($arg1), function($files_arg1){ return is_file(arg1 . "/" . $files_arg1); });
    $main_folders = array_filter(scandir($arg1), function($folders_arg1){ return is_dir(arg1 . "/" . $folders_arg1); });

    // Remove dots from main_folders
    $main_folders = array_diff($main_folders, array('..', '.'));

    // Add all files from main_files to the files array
    foreach($main_files as $main_key => $main_value){
        $files[] = "/" . $main_value;
    }

    // Check subfolders
    foreach($main_folders as $sub1_key => $sub1_value){
        // Analyze subfolder
        $sub1_files = array_filter(scandir($arg1 . "/" . $sub1_value), function($files_arg1){ return is_file(arg1 . "/" . $GLOBALS['sub1_value'] . "/" . $files_arg1); });
        $sub1_folders = array_filter(scandir($arg1 . "/" . $sub1_value), function($folders_arg1){ return is_dir(arg1 . "/" . $GLOBALS['sub1_value'] . "/" . $folders_arg1); });

        // Add all files from sub1_files to files array
        foreach($sub1_files as $sub1_add_key => $sub1_add_value){
            $files[] = "/" . $sub1_value . "/" . $sub1_add_value;
        }
    }
    return $files;
}
foreach (scanfiles(__DIR__) as $key => $value) {
    echo "<br>" . $value;
}
?>
