PHP查看文件夹下文件数和代码行数

以下是一个用 PHP 编写的递归查看文件夹下文件数和代码行数的简单示例：

<?php

function countFilesAndLines($directory, &$totalFiles = 0, &$totalLines = 0) {
    $files = scandir($directory);

    foreach ($files as $file) {
        if ($file == '.' || $file == '..') {
            continue;
        }

        $filePath = $directory . DIRECTORY_SEPARATOR . $file;

        if (is_dir($filePath)) {
            countFilesAndLines($filePath, $totalFiles, $totalLines);
        } elseif (is_file($filePath)) {
            $totalFiles++;
            $totalLines += count(file($filePath, FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES));
        }
    }
}

$directoryPath = '/path/to/your/folder';
$totalFiles = 0;
$totalLines = 0;

countFilesAndLines($directoryPath, $totalFiles, $totalLines);

echo "Total files: $totalFiles\n";
echo "Total lines of code: $totalLines\n";

请将 /path/to/your/folder 替换为你要检查的文件夹路径。这个脚本会递归遍历文件夹，统计文件数和代码行数。
