I am using apache server under xampp. I have some matlab exe file that I want to execute. I used this template
$tmp = exec($command, $output, $return_var);
while $command contains the exact command to execute the file using cmd.
What is happening is the page hangs and when I debug, I found that the server hang while calling this exec command.
I searched the web and tried many things like run the Apache service and my user account and give the user all administrator privileges, but unfortunately it still stuck.
Any help or advice would be appreciated.
The problem with my code was because the Matlab code is accessing file system and also reads an excel sheet. So, it was all about permissions.
The solution for this problem has 2 parts:
1. Apache should run as a a windows service with checking allow service to interact with desktop in the properties.
2. I found that there is no way to access windows COM objects to read excel in normal way. So, instead we should use xlsread in basic mode.
That's all.

I'm trying to create a Cordova project in a PHP script, using :
$command = "cordova create test";
exec($command);
This doesn't work because the cordova command (which is a NodeJS plugin) is only available to the normal Windows user, and not the local system account that runs the Apache service (so also not to PHP).
I found some answers on here that relate to linux, but I need this to work on Windows.
Is there a way to change the user that runs exec() to my normal Windows account?
UPDATE
After adding C:\Users\<ACCOUNTNAME>\AppData\Roaming\npm to the PATH variable it works. That's where the cordova.cmd file is located (on my system).
Make the binary available to the system account. That's it.
I'm using PDFTK to merge some PDFs on my Amazon EC2 instance running Windows Server and IIS7.
When I try running PDFTK using PHP exec(), it does not work. For example:
<?php
$e = exec("pdftk");
var_dump($e); //output is: string(0) ""
?>
I can get other commands to work using exec such as exec("ping 192.168.2.1") but I can't get PDFTK working.
I can also run pdftk from DOS command line, so I know it's installed properly.
I also set the permissions to pdftk.exe to full access for all users (thinking this was a permissions issue).
I remember having a similar problem when I installed PDFTK on another Windows Server Amazon EC2 instance, but I forgot exactly what I needed to change. I thought it had something to do with IIS_USR Permissions but it was a while back and I don't remember the specifics.
Thank you.
The application either needs to be in the same directory as the script, or within the $PATH environment variable for the user executing the PHP script. With IIS, this is not the user you are logged in with.
I have tried to use the Zend Framework to do my PDF conversion in PHP but cannot figure out how to install it. I found this program that allows for PDFs to be printed/converted via the command line, so I thought I could do an exec() command in PHP to run the program and convert my file on the server for me.
The program is PDFCreator from pdfforge.org and I am trying to convert .DOC files to .PDF files. This command line below works perfectly when running from cmd.exe. However, when running it from PHP I believe that it is trying to execute under the user System and not working properly. (I did a php exec('whoami') and it came back as System.) I also changed the user of which Apache opens up as to an Admin account and still have been unable to get it to work.
"C:\Program Files\PDFCreator\PDFCreator.exe" /OptionsFile"C:\PDFCreator.ini" /PF"C:\test.doc"
Any thoughts as to why it I cannot get the same behavior when running the command using exec()?
Thats because Apache user and account user should be the same, ex: your windows user is Pedro, so Apache user should be Pedro...you shoul open the services.msc and in the session tab allow apache to interact with the current desktop....in that way, the share the same windows session and desktop....but it shoud represent a security risk and it's not recommended.
Saludos.
i read so many similar questions but nothing works with me
im using wamp 2.2 ,Apache 2.0 , PHP V5.3.8
safe_mode=off - disabled_functions deleted from php.ini i'm trying to exec
exec("chrome.exe google.com");
nothing happens and when i try
exec("calc");
the windows shows weird message to execute calc in different user although i changed the user for the apache service to Administrator and i verify the user using
exec("whoami");
where is the problem?
Environment path for CMD and php shell might not be the same.
You either have to give entire path of the file, or export the path of chrome.exe in php first
Also, I believe that chrome.exe opening a page requires XServer, php can't open graphical interfaces in shell. These commands are not passed to actual shell as a parent, so php file can't "launch" applications for you.
Please read specifics of the exec function:
PHP exec Reference
Also try adding 2> errors.txt to see what are the errors if any in the execution of the programme.

The program needs to know what X server to connect to, and it needs to have permissions to connect to that server. You specify the X server with the DISPLAY environment variable; this will usually be set automatically if you are running the PHP program from a terminal in
X, or from a GNOME panel or something similar; however, if you are running the PHP script in some other manner, it likely won't know what X server to connect to.
X has various ways of specifying permission to connect to a server, but the most common one is using a file called ".Xauthority" in the users home directory. Because only the user who is logged in at the X server can read this file, they are the only user who can run GUI programs. So, if you start the PHP user as the same user who is logged in at the X server, you shouldn't have any problem with permissions. However, if the PHP program is running as a different user, you will have to give that user permission to access the X server.

(I know that link is for linux and won't have exact same solution for Windows, but exec() still needs to know which X interface to refer to)
Stop Apache running as a service.
When windows runs a service it it is not running directly as the user that started the server or manages due to this it could well be starting chrome in a service environment so you wont see it load on your desktop there are 2 ways to get around this
Stop apache service browse to your apache directory and run httpd.exe manualy then try your script it should work or if it is not required to be running though a web request so it not using anything from the browser you can allow it to work with c:\wamp\php\php.exe yourfile.php (your php path should be replaced for c:\wamp\php)
Try PHP script?
<?php shell_exec('notepad.exe');?>
It's working.
I am looking into a way to reboot a remote dedicated server using php. While doing research on Google I read about Python shell client. Is there is something similar in php?
Can I use php to reboot a remote server using shell commands? and what is needed to do so?
I assume that you want a web based shell implemented in php.
In that case you can look at this http://ajaxshell.sourceforge.net/
and this http://sourceforge.net/projects/ajaxshell/
Using these scripts you can run arbitrary shell commands.
But remember 2 things.
1. password protect the web shell app
2. The shell will run commands as the apache user. If you want to reboot the server, apache may need root privileges. Running apache as root is usually considered as not a good practice.
You probably can, by using exec(), passthru() etc. Is it a good idea, I'm not sure : you'll have to give reboot privileges (I don't know exactly, but it's almost root...) to your php user.
Just to be sure, what you want to do is to call a web page that will reboot your server, or it's more complicated that that?
There is a shell equivilent for PHP. I recently published a project that allows PHP to obtain and interact with a real Bash shell, you can even easily get a shell with root. Get it here: https://github.com/merlinthemagic/MTS
After downloading you would simply use the following code:
//if PHP is running on the server you want to reboot:
$shell = \MTS\Factories::getDevices()->getLocalHost()->getShell('bash', true);
//if PHP needs to SSH to the server first
$shell = \MTS\Factories::getDevices()->getRemoteHost('ip_address')->getShellBySsh('username', 'password');
$strCmd = "reboot";
$return1 = $shell->exeCmd($strCmd);
