does anyone know how to run php as root temporarily?

I have some install script I want to write and dont want to login ssh and run "php script.php" I would rather run them from a browser, then delete them when done.

Ideas ?

Wouldn't you need to log in to run PHP as root anyways? :scratchhead:

Yeah that's what I want to avoid.

I found this:

Code: [ Select ]
<?php
shell_exec('sudo -u root -S command_goes_here < /home/$user/dir/passfile');
?>
  1. <?php
  2. shell_exec('sudo -u root -S command_goes_here < /home/$user/dir/passfile');
  3. ?>


Or this...

Code: [ Select ]
<?php
$password = $_GET['password'];
shell_exec('sudo -u root -S command_goes_here < $password');
?>
  1. <?php
  2. $password = $_GET['password'];
  3. shell_exec('sudo -u root -S command_goes_here < $password');
  4. ?>


Then I can just make a temporary file with the password, or enter it from an <INPUT> tag and do what I need to do. Then delete the temp file when work is done.

You shouldn't have to run any web-related php scripts as root, ever. If you've written one that requires root you're doing it wrong.

By the way, never, ever take passwords through an http get. Also if you're gonna pass some user input to shell_exec you'd better sanitize it.

Hi, As we know that php is a server side scripting language, means no way that, it's program run without server, i.e on local browser, then you first install server, like Apache, see them
[WAMP] => window + Apache Server + MySql + php.
Now I mention here Editor like Adobe Dream Weaver, where you write code having extension is .php,
now you save it in root folder
Path : C:/D:/E:/F:/ = >wamp => www => you create folder(Like php app.) =>php_script.php

and still you face some problem then just mention here.
