I'm trying to call the nbtstat command from PHP using shell_exec(). Apparently that doesn't work because I'm using a 64-bit system.
echo shell_exec("nbtstat");
I've done some research and it seems that the problem is caused by the fact that Windows 64-bit defaults to \Windows\SysWOW64 as System32 folder. But nbtstat is located in the normal \Windows\System32 folder.
In normal applications you can call Wow64DisableWow64FsRedirection to disable this redirection, but I haven't managed to find this in PHP yet.
Is there a way to actually call these commands from PHP within a 64-bit Operating System?
Add "\Windows\Sysnative" to the end of your environment path.
What you need to do is to grant the IUSR_<machinename> user Read & Execute / Read permissions not on the C:\WINDOWS\SysWOW64\nbtstat.exe file, but instead on the C:\WINDOWS\SYSTEM32\nbtstat.exe file.

When I try to use Webception over wamp server on my windows 7,8 the below error appears for each tests
'php' is not recognized as an internal or external command,operable program or batch file
I have already installed php and the path is correct. Does it need more setup? How I can fix this issue ASAP?
This is because windows does not know where to find the php.exe file as it is not in a folder that is on your PATH environment variable.
However, when using WAMPServer it is a VERY BAD IDEA to add the path containing the php.exe to your PATH in the traditional way, because of course in WAMPServer it is possible to have many version of PHP available within one instance of WAMPServer.
The best solution in a WAMPServer environment is to create yourself a little command file that you can run from within a command windows that will add the php path you want to use for this specific project.
So create yourself a .cmd file and place THAT file in a folder that is already on your windows PATH environement variable.
So for example :-
File = phppath.cmd
PATH=%PATH%;c:\wamp\bin\php\php5.5.12
ECHO --------------------------------------------
php -v
ECHO --------------------------------------------
Of course you can make this as clever as you like and accept parameter specifying the php version you want to run, but untill you actually have more than one PHP version installed this is good enough.
I was also having a problem with webception on wamp failing to find php despite it being available on user and system path.
I found that wamp on windows by default does not provide environment variables to PHP.
I fixed this by editing php.ini (in apache/apache/bin/php.ini)
and ensuring that the following is set
variables_order = "EGPCS"
As at the current webception version 0.1.0 there is a bug to do with path generation that fails tests because the test file cannot be found. There is a solution for this at https://github.com/syntithenai/Webception/
I have run into a truly strange issue for which i have no explanation whatsoever.
After setting up OS X Yosemite and my local dev environment using XAMPP, i installed ImageMagick through MacPorts. All is well, it runs perfectly fine on the commandline.
However, when executed through Apache and called through PHP, i get no output from it whatsoever.
I have done extensive research and found a variety of approaches:
Setting the path environment variable in Apache (which i tried)
Using an absolute path to the executable (which i do)
Checking if exec() is listed as a disabled function (which it is not)
Checking if convert is even callable, as in executable (which it is)
I even went as far as copying the convert executable to the local project root directory and trying to exec('./convert'); but to no avail. I always receive absolutely no output from that call. Not even an error message. Needless to say, when i run the same thing through the Terminal, it works fine.
I also tried:
Calling exec('ls'); to see if anything comes up at all (yes it does, that works fine)
Calling exec('which convert');, where i get no result at all - the call returns nothing
Calling exec('which ls'); to double-check if the problem was with which - but which ls works fine and gives me /bin/ls as a response.
Providing chmod 0777 to the executable - to no avail
Regardless from what i try or do, convert remains entirely untouchable to PHP/Apache.
Can anyone tell me why that is and how to remedy it?
Checking the Apache error logs, i found the following message:
dyld: Library not loaded: /opt/local/lib/libfreetype.6.dylib
Referenced from: /opt/local/bin/convert
Reason: Incompatible library version: convert requires version 18.0.0 or later, but libfreetype.6.dylib provides version 15.0.0
Research showed that there is a common approach changing some environment path variable that applies to Apache and its subsidiary processes while running. However, since i did not want to fiddle around like that, i went for a somewhat more raw approach:
I opened a terminal and went to the very root directory of my system. There i ran:
find . -name "libfreetype.6.dylib"
This gave me all the libfreetype.6.dylib files that were available on my system. One of them was in the XAMPP lib directory, another one was in /usr/local/lib.
I backup up the file in the XAMPP directory and then copied the one from /usr/local/lib there.
I then tested convert again through Apache and was given another, quite similar error message relating to libexpat.1.dylib. For that i repeated the copying process as above. Afterwards, convert was executable through Apache and the problem was solved.
When you run scripts and programs via your web server, they are being run by a different user. In Macs this is usually _www. The convert application can't be found because the path to its executable file (probably /usr/local/bin) isn't included in the $PATH environment setting for this user.
The simplest solution is just to prefix the command with the path to convert, i.e., exec('/usr/local/bin/convert ... ');
My setup is as follows: Windows 7, XAMPP with Apache and PHP enabled I have a PHP script in which I call an external program to do run a conversion. This external program is an EXE file, which requires 3 attributes:
The source file
The destination file
Additional flags (conversion type etc)
When I use the command line tool built into XAMPP to execute my script, everything works fine. But when I use the exec() function in my PHP script, no output file is created. I'm pretty sure the conversion is actually happening (it takes about 5 seconds, about the same time it takes to run the PHP script).
I think it's a permissions thing, so I already moved the EXE file to the same folder as my PHP file and adjusted the permissions of the entire folder (I granted all permissions to all users). I also disabled the Windows UAC and tried to put the command in a BAT file. The file just is not created.
Any help or tips would be greatly appreciated!
My PHP code is as follows:
exec('c:\converter.exe c:\src.txt c:\dst.txt -f', $output);
print_r($output);
When I print out $output, the array turns out to be empty. When I put the exact same command in Command Prompt, the code works like a charm (no syntax errors). I use absolute paths as well.
Try to copy your executable file in same folder as your application.
try
exec("script.exe src.txt dst.txt", &$output);
echo $output;
also, do not forget to use escapeshellcmd() to add some security to your application.
Thank you very much for your input! As it turns out, it was Windows issue caused by the 'Interactive Services Detection' feature. Apache was running as a system service, which prevented calls to external programs (with a GUI). I disabled the run-as-service feature in XAMPP, which solved the problem.

I have a web accessible PHP script that is using a shell command to drop PDFs to text. I installed Poppler, and am using pdftotext, via MacPorts. I am able to run the command successfully from the CL, and when supplying the full path within the PHP script to '/opt/local/bin/pdftotext'. So, I know that my $PATH is correct and the permissions are sufficient, yet I am still getting an exit status of 127: Command Not Found, when attempting to do simply 'pdftotext' in the exec().
I have tried the answers from How do I add paths to the Apache PATH variable? and http://lists.apple.com/archives/macos-x-server/2008/Sep/msg00433.html. I modified both the /etc/paths and /etc/profile, and added /etc/paths.d/macports all pointing to '/opt/local/bin'. setenv, apache_setenv, etc all had no effect also.
I am using a MAMP (1.9 I think) install for my local development, OSX 10.6, PHP 5.3.5, all a little behind I know :-) ... my $PATH is modified to point to the MAMP bin/php
/etc/paths.d/macports will influence on PATH variable for macports, not for the Apache. You probably need to add /etc/parhs.d/apache (or else) to do what you need.
Edit: also check this and this threads for solutions. It is somewhat outdated but still can help.
Specifically, I'm trying to get ViewGit working on a PHP/Apache/Windows installation.
It seems that PHP is unable to run exec('git');.
exec('whoami'); works just fine, so it isn't a problem with exec() being disabled.
Apache is running under it's own user account- if I log in as this user and attempt to run git on the command line I get the expected results. The account also has full permissions to do everything with the /Program Files/Git folder.
If I run exec('git'); on my local machine it works fine, but just won't work on the server.
Any ideas?
When you type 'git' in command-line on Windows, it opens git.cmd. In typical msysgit installation on Windows, git.cmd is in PATH, but git.exe may not be!
So, you can try one of below:
Create a git.bat in Windows folder with following contents:
C:\Program Files (x86)\Git\bin\git.exe (check path)
Add git's bin directory also in Windows PATH. (You can do so by editing system environmental variables)
I've managed to fix this by upgrading from PHP 5.2 to PHP 5.4. Not sure what the issue was, but that has resolved it.
