Google App Engine(php): glob() function

Question

I used glob() function in my application which is hosted on Google App Engine and my text_files are on Google Cloud Storage. It doesn't work and return false. Here is the code:

$links = glob("gs://bucket_name/folder/textfile_*");
if($links){
    echo "true \n";
    print_r($links);
}else{
    echo "false";
}

And my files on GCS are like this:

textfile_Ben.txt
textfile_Sam.txt
textfile_David.txt

I checked the http://php.net/manual/en/function.glob.php and it says:

Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

My application works fine with other functions such file_get_contents() or file_put_contents().

Question: Is there any solution for using glob() function or is there any alternate method to do the same functionality?

glob won't work with a url, only file system paths. This answer might help http://stackoverflow.com/questions/6997887/glob-not-giving-me-any-results — abstr, Oct 05 '13 at 02:52

Use opendir/readdir and filter the paths yourself.

It's the only way I reckon. The only issue is that it doesn't work with sub-directory. I can only use `opendir("gs://bucket_name/")` It doesn't work with `opendir("gs://bucket_name/folder/")` – Behnam Rasooli Oct 06 '13 at 01:39
You should be able to opendir a subfolder. If it's not working can you open an issue in the tracker? – Stuart Langley Oct 06 '13 at 08:48
I don't know what you mean by "open an issue in the tracker" Where is tracker? – Behnam Rasooli Oct 06 '13 at 13:59

I have got the solution :)

$folder = "gs://bucket_name/folder";
foreach (new DirectoryIterator($folder) as $fileInfo)
{
    echo $fileInfo->getFilename();
}

cheers
