When you say does not work, can you show what is actually not
working? I
believe the exec and system functions are likely working just fine,
but that
the commands you've passed to them may not be.

If I perform the touch and chmod from the command line, everything
works.

Ethan - YOU'RE DOING IT AGAIN!!!

Either you are not using error checking AGAIN!!
OR
You are showing us re-typed in code that YOU DIDNT ACTUALLY RUN.

I've told you multiple times that you need to do these two things and
you are back at it again.

The sample php above has plain simple syntax errors that would keep it
from running, which error checking would tell you IF YOU RAN IT.



Jim -

you have semis after your if lines - therefore no logic gets executed.

Hi Ethan,

Is there a reason you're using shell commands to achieve the following:

?php

$path = '/var/www/orders.txt';
if( !file_exists( $path ) )
{
if( !touch( $path ) )
{
echo 'Failed to touch file into existence: '.$path.\n;
}
else
{
if( !chmod( $path, 0766 ) )
{
echo 'Failed to update file permissions: '.$path.\n;
}
}
}

?

Also, why are you setting the executable bit on a text file? :)

Cheers,
Rob.

   When you say does not work, can you show what is actually not
 working? I
   believe the exec and system functions are likely working just fine,
 but that

 Here are my commands.
 
 if( !file_exists(/var/www/orders.txt));
 {

 echo system(chmod 766 /var/www/orders.txt, $ret);
 echo 'file2br /';
 echo file_exists(/var/www/orders.txt);

 If I now try a ls from the command line, the return is
   cannot access /var/www/orders.txt: No such file or directory
 
 The ls -la  works because the file was created from the command line.

Note that touch and chmod don't return any output, so echoing the result of 
a system call for those commands will give an empty string.

You should be checking the values of $ret for each execution of system to 
see whether the command was successful or not - the return status of the 
executed command will be written to this variable. I'd guess that touch is 
returning 13 - permission denied.

if( !file_exists(/var/www/orders.txt))
{
  system(touch /var/www/orders.txt, $ret1);
  echo 'touch returned '.$ret1.'br /';
  system(chmod 766 /var/www/orders.txt, $ret2);
  echo 'chmod returned ' .$ret2.'br /';
  echo 'file2br /';
echo file_exists(/var/www/orders.txt); }

Check the permissions for directory /var/www; you'll probably find it is 
writable by the user you log on as, but not by the user that apache/php runs 
as, which is often www - a user with limited privileges.

As other(s) have pointed out, there are php functions to do what you want 
without introducing the possible insecurities involved with system et al.

When you say does not work, can you show what is actually not working?
I believe the exec and system functions are likely working just fine,
but that the commands you've passed to them may not be.

Re: [PHP] exec and system do not work

2013-08-26 Thread Jasper Kips 
Ethan,
A return code of not 0 means an error occured.
Probably /var/www is not writable. Test that one by doing this:
$a = is_writable(/var/www);
var_dump($a);
If that says anything else than (boolean) TRUE, you can't write in the 
directory. 


Sincerely,

Jasper Kips

 touch returned 1
   /chmod returned 1
 

Non-zero return value indicates an error; touch failed and as a result there 
is no file to chmod, hence chmod also failed.
