PHP exec() to compile VB6 from CMD - php

i'm pretty new to PHP and i need to compile a vb6 project from windows command prompt.
I've tried everythig but nothing seems to work, even creating a batch and execute from PHP code, no way... (the batch works if launched from cmd itself).
I also defined variables with various paths with no success.
i.e.:
$cmd = ('vb6.exe -MAKE D:\Websites\devopservices\dlledit\portaleeditorisen\NewSecurity\Data\NewSecurity_data.vbp D:\Websites\devopservices\dlledit\compiled\test.dll');
echo exec($cmd);
or inserting paths with variables:
$proj = 'D:\Websites\devopservices\dlledit\portaleeditorisen\NewSecurity\Data\NewSecurity_data.vbp';
$dll = 'D:\Websites\devopservices\dlledit\compiled\test.dll';
here it is the full command i need to execute:
<?php
echo exec('"C:\Program Files (x86)\Microsoft Visual Studio\VB98\VB6.EXE" /MAKE D:\Websites\devopservices\dlledit\portaleeditorisen\NewSecurity\Data\NewSecurity_Data.vbp D:\Websites\devopservices\dlledit\compiled\NewSecurity_Data.dll');
?>
Thanks for your help.

I resolved, it was not a php issue but related to identity in IIS appilcation pool :-)

Running gcloud command in php not working

I am trying to run shell commands from PHP using
<?PHP
$output = shell_exec('gcloud --version'." 2>&1");
echo "$output";
?>
The output which I get is
sh: 1: gcloud: not found
When I try to do
shell_exec('ls -l')
It works as expected. I have related posts on StackOverflow to use Rest API instead on this. But I have created a big script with gcloud commands. I am running my shell scripts in Terminal in mac. Can anyone help me understand the issue. May be required to install sdk, tried that still got same issue.
You need to read up on Relative Path vs Absolute Path of a file/dir.
When you code shell_exec('gcloud --version'..., you are using relative path.
One way to resolve your issue is to specify the absolute path to gcloud command which can be determined from bash command line by typing:
which gcloud and you might get a result like
/usr/lib/google-cloud-sdk/bin/gcloud
Then, change your PHP code to shell_exec('/usr/lib/google-cloud-sdk/bin/gcloud --version'...

PHP exec not working for compiling on Windows 8 through Visual Studio 2012 Command Prompt

Thank you for taking the time to help me today. I have what I hope is a simple question. I have been attempting to use php exec() or any related PHP command to Open up the Developer Command Prompt for Visual Studio 2013 and use it to compile a file and save the output to a file on my local machine. I have it working fine from Run on Windows, but I can't seem to get it to work with PHP exec(). Here is how I have the command set up currently.
$cmd = 'C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\VsDevCmd.bat && cd C:\wamp\www\csc424Try3\app\uploads && cl /EHsc basic.cpp && basic >> C:\wamp\www\csc424Try3\app\outputs\output.txt';
exec($cmd, $result);
As you can see, I am chaining together commands. The first command allows the prompt to open, the second changes to the proper directory, the third runs the command for compiling in the prompt, and the fourth outputs to a text file.
Any ideas where I'm going wrong? I had a feeling it had something to do with formatting, but perhaps chaining the commands together does not work in PHP the way it does on the system.
You're forgetting quotes around most of your arguments in the exec call's string, meaning that things like Program Files will be seen as two separate things, not a single directory.
$cmd = '"C:\Program Files (x86)\....VsDevCmd.bat" && etc...';
^-- ^-- need these
as is, you're trying to execute a program called C:\Program, with some extra arguments like Files (x86)\......
I found the answer to my own question after some research. The way I was trying to do it before just wasn't working. After talking to a colleague, I thought writing a .bat file for the background would work better, and it absolutely did. I wrote the chain of commands in a .bat file and executed it like follows;
system("cmd /c C:\wamp\www\csc424Try3\app\uploads\stuff.bat");
Success! The file can now be successfully compiled and ran from PHP. :) It is a good day.

Problem with passthru on server

I have a problem trying to run passthru function in my php code (Joomla module). the code is following (this is only a snippet)
ob_start();
passthru("/usr/bin/whois 85.70.231.130 | /usr/bin/grep 'address:'",$code);
$whoisData = ob_get_contents();
ob_end_clean();
$whoisData = str_replace("address:", "", $whoisData);
$whoisArray = split("\n",$whoisData);
echo trim($whoisArray[1]);
when I run this on my localhost, it echoes what it should, but when I run this code on the production server, it echoes nothing and the $code variable contains 127 (command not found). I tryied add absolute paths to these commands into the passthru function, but it didn't helped. Interesting is, that when I run the code right from terminal via ssh and php command, it runs well, but when it's called from application context it doesn't. Does anybody know what I should to do?thanks
SOME EDITS..
safe_mode is on
webserver does not see into /usr/bin and /bin/ folders so what is the best way how to run these commands from php?
usr/bin/grep doesn't look like a valid path to a command.
The missing / at the beginning of the path to the second command might explain the command not found error... even if the first whois command is found.
Have you looked to see if your webserver / php is running chrooted?
print_r(glob('/*'));
if (file_exists('/usr/bin/grep') && file_exists('/usr/bin/whois')) {
print "maybe its a permissions thing?\n";
} else {
print "can't see executables required\n";
}
should give you a clue.
So I have already solved my problem with phpwhois library. I seems like with my server configuration is it unlikely that these functions will be working well. So thanks for your help:)

PHP exec python not working

hey yall. Im running python on a webserver from dreamhost. I am using their install of python and am using a lastfm module that can be found here: http://code.google.com/p/python-lastfm/
to get it to import properly i do this
import sys
sys.path.append("/home/myusername/build/Python-2.5/Lib/site-packages/")
import lastfm
since the lastfm module is installed there.
When I use putty to ssh into my server, i can simply run python test.py and it works perfectly. But when i run it from a php script with
exec("python test.py");
it suppossedly does not work and the script doesnt run. it runs perfectly fine when i do
import lastfm
and then have other things after,
but when i actually try to do something with the module like:
import lastfm
api=lastfm.Api(api_key)
it does not run. once again i can run the script using the same python install in a shell and it executes fine. So something must be happening that goes wrong when i run it from the php script. I figured it would be running the exact same python and everything. I checked other posts and they say it may be something with file permissions, but ive put every file to 777 and it still doesnt work. idk what the problem could be. thanks in advance everyone.
Try using the full path to the python executable. For example:
exec("/usr/bin/python test.py")
You can find the full path from the command line using the which command:
$ which python
/usr/bin/python
Whatever error python is raising would be going to the child's stderr. Try either telling php to read from stderr, or (in python) do this:
import sys
sys.stderr = sys.stdout
For Windows users:
$output = null;
exec('C:\\Python27\\python.exe C:\\sud.py', $output);
echo var_export($output, TRUE);
The code i was searching whole day ^^
That's why - hope it'll help somebody.
For Windows User -
Thanks to Karlisup my PHP file could read python.
I'm using BITNAMI WAMP in EC2 Amazon, my python file (leadatos.py) and php file are on htdocs folder.
My calling was
<?php
passthru('C:\\Python27\\python.exe leadatos.py');
?>
The last line of my Python file was print "message".
Hope it words!

Problem using PHP exec command to execute a batch file

I'm attempting to get PHP to call a batch file which will take an RTF file and convert it to a PDF using an OpenOffice macro. I've tested the batch file on the command line and it works fine, but I'm not having any luck calling and using the same batch file from PHP.
My machine OS is XP professional SP 3. I'm running IIS 6 and PHP version 5.2.9.
I've granted execute permissions to the internet user on c:\windows\system32\cmd.exe.
I specified the full path to the batch file being executed and the full path to the RTF file to be converted.
The PHP looks like this where $arg is the RTF to be converted:
$arg = "C:\\web_root\\whatever\\tempOutput.rtf";
$command = "c:\\windows\\system32\\cmd.exe /c c:\\web_root\\whatever\\convert.bat $arg";
Then inside a try-catch I call the exec command:
exec("$command 2>&1 && exit", $ret, $err);
I echo the results after the catch:
echo "ret: ";
print_r ($ret);
print "<br>";
echo "err is ";
echo $err;
print "<br>";
echo "DONE!";
And this is what I see:
ret: Array ( )
err is 0
DONE!
The RTF file does not get converted and I'm not seeing the errors. Any ideas on what I can try next? Thanks!!!
I'm going to bet this is about permissions.
In a typical setup, PHP runs as apache - so you'll want to make sure apache has the rights to execute the batch file.
also, check this relevant SO question, and this google search.
Looks like the output array is empty. Is your batch script supposed to have output?
Also, escapeshellcmd and escapeshellarg should be used
Are you using IIS as your webserver? If so, the PHP exec function will not work by default and you should NOT circumvent the security measures that prevent it from running.
Check your event viewer and you should find some errors pertaining to your problem. Run a query through google for: IIS PHP exec. This should give you a large selection of information about the problem.
Basically, the PHP exec function tries to fork a new cmd.exe instance. IIS prohibits this because it could open a security hole in the system.
The best solution that I have come up with is to have your php script either write the command that you want to execute to a flat file or make a database entry. You will then need to write a seperate script that is launched by the windows scheduler to run every 10 minutes or so that will check your flat file or database for commands to run. The new script will then run the commands and then place either the results or an execution confirmation that your web app will be able to access at a later time.
It's a kludge for sure.
Is PHP running in safe-mode? If so, shell commands are escaped with escapeshellcmd. Perhaps this is the problem?
Do you have control of the server running the PHP script?
