获取指定目录下的所有图片信息

1 获取指定目录下的所有图片信息

// 获取指定目录下的所有图片信息
    public function getImagesInfo($directory)
    {
        $images = [];
        // 创建递归目录迭代器
        $iterator = new \RecursiveIteratorIterator(
            new \RecursiveDirectoryIterator($directory, \RecursiveDirectoryIterator::SKIP_DOTS),
            \RecursiveIteratorIterator::LEAVES_ONLY
        );
        // 遍历目录中的每个文件
        foreach ($iterator as $file) {
            // 检查文件是否是图片
            if (is_file($file) && in_array(strtolower(pathinfo($file, PATHINFO_EXTENSION)), ['jpg', 'jpeg', 'png', 'gif', 'bmp', 'webp'])) {
                // 获取相对路径
                $relativePath = str_replace($directory . DIRECTORY_SEPARATOR, '', $file->getPathname());

                $images[] = [
                    'filename' => $file->getFilename(),
                    'size' => $file->getSize(),
                    'extension' => $file->getExtension(),
                    'relative_path' => $relativePath
                ];
            }
        }
        return $images;
