php recursive iterator php8.1 PHP

I'm relatively new to this, so bear with me. I'm facing an issue when trying to recursively iterate through directories using `RecursiveIteratorIterator` in PHP 8.1. My goal is to read all files in a given directory and its subdirectories, but I seem to be encountering unexpected behavior where it outputs directories instead of files. Here's the code I'm using: ```php $directory = '/path/to/directory'; $iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)); foreach ($iterator as $fileInfo) { if ($fileInfo->isFile()) { echo $fileInfo->getFilename() . "\n"; } else if ($fileInfo->isDir()) { echo "Directory: " . $fileInfo->getFilename() . "\n"; } } ``` I've confirmed that there are indeed files in the specified directory, but the output is not what I expect. Instead of listing just the files, I see that it's also listing some directories. I tried adding a condition to specifically check for files, but it seems like the `isFile()` method is not behaving as expected. I also checked for any hidden files or permissions issues, but everything seems normal. The directory structure is as follows: ``` /path/to/directory/ ├── subdir1/ │ ├── file1.txt │ └── file2.txt ├── subdir2/ │ └── file3.txt └── file4.txt ``` When running this code, I get output similar to: ``` Directory: subdir1 Directory: subdir2 file4.txt ``` This behavior is unexpected, as I thought `RecursiveIteratorIterator` would only yield files if they are files. Is there something I’m missing in my implementation, or is this a known issue with PHP 8.1? Any insights would be appreciated! Thanks in advance!
