Strange problem occured while trying to create a CSV file - The file is not seen on FTP but can download using file's absolute path url
Last day I came across a strange problem when I tried to create a csv file on therver using a PHP script.

the script was simply writing a given content as a csv file. The file will be created runtime.

What happened was, The script executed fine, file handler for new file was created and contents was wrote into the file using fwrite and it returned the number of bytes that was written.

Strange thing was, even though the file was written, I couldn't see the file on specified directory. Then I thought, I might have given an error path, I checked all the folder but couldn't see the file. then I put a mail function with in the file write script to email the content and number of bytes written. It worked fine but couldn't see the file on server. Then I tried to check the CSV absolute path. I took it on the browser and I could download the CSV file.

file path: TES000001.csv

I am very much confused on this ..can any one help?

I had not set any file permissions using the script (using chmod function).

here is the code I used:

$file_content="THIS IS A SAMPLE CSV FILE ";
$fp = fopen('TES000001.csv', 'w');
fwrite($fp, $file_content );

is this file created as hidden. If So why this happens. How can I fix that?


When I tried to upload a CSV in same name to the server, it asked for overwriting

When I checked through the CPANEL file manager, I could see the csv files, so this must be something related to the FTP software

All the csv files in the folder has 0644 permission

I was using Filezilla for FTP
Server is Linux Apache
Script : PHP
Checked in Chrome, FF and IE all returned same result

Atlast found the issue :)

it is due to presense of some  FTP software specific  ley words in the created file name. when I renamed the file's name through cpanel file manager and then looked through the FTP window, I could see the file.
