permissions - PHP: Check if script is being ran with sudo or if user is not using `php` -

How to find out how the script is running with sudo access or not using PHP?

^{Note: this question would probably be more appropriate on stack overflow, though it can be used on Unix & amp; Refers to PHP; Linux system (privilege upgrades, permissions, etc.)}

You can use PHP's POSIX functions:

• To get effective user IDs.
• To get user information from the UID.

Here is a short example:

  & lt; Php $ userinfo = posix_getpwuid (posix_geteuid)); Echo "This script is running" $ Userinfo ["name"] "'Privileges.'"; ? & Gt;  

test ...

  $ php myfile.php This script runs with the privileges of my user. $ Sudo php myfile.php This script runs with the privileges of the root  

Anyway, because the root is always UID 0, you can simply posix_geteuid () == 0 .

You now want that the user is using CLI (command line) or going through a web server, but have a look and function.

^{Another note: I'm pretty sure that running PHP script in the form of root is not the best of ideas. You can think again what permission your script is actually allowed.}
