Determine if a file is a system file or not and also the owner of the file using php

I'm trying to figure out a way to determine if a file is a system file or not using php. I also want to know the owner of the file and the domain owner.

I have tried different ways to determine if a file is a system file or not, i.e. is_file()

, fileperms()

. Then I plan to construct a function around the name of the file that returns true, if the file extension, such as .ini

, .db

, .tmp

, etc., or a file name that begins with "` ". Let me know if anyone has an idea to do this.

Also, I am trying to figure out the owner of the file and the domain of the owner, for example "NTRSK\USER1"

for this I tried

$stat = stat($file);
// returns 0 always   

echo(posix_getpwuid($stat['uid']));
// got fatal error 'undefined function posix_getpwuid()'

I'm tired too fileowner($file);// returned 0

, I need something like "NTRSK\USER1"

.

You must use command line execution if you are on Linux



<?php
$output = shell_exec('ls -lh'); <-- for an example
echo "<pre>$output</pre>";      <-- use the output value to determine file status or owner depending on which command you're using. 
?>
