PHP exec('git') failing - php

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.

VsCode php.validate.executablePath, after insalled XAMPP

i'm trying to set the certain path for the php extension in my vscode (using linux)
i started installing the XAMPP
and after it..i tried to use the extension writing some php scripts(php extension INTELLISENSE and DEBUG), but the extension is not working properly and it's showing that error:
Cannot validate since /usr/bin/php is not a valid php executable. Use the setting 'php.validate.executablePath' to configure the PHP executable.
i tried to set it using que path which is provided by vscode documentation, but it's still no working.
Can anyone help me !! please!!!
I found a solution, typing in terminal
'whereis php'
that returns the absolute path for set it in the vscode extension
/opt/lampp/bin/php
Then, setting the path in the follow line
php.validate.executablePath: "/opt/lampp/bin/php",
So, I hope this solution is helping someone behind the screen.
Php path in windows
Typing in terminal
where php
And it'll gives the path as (in my case)
C:\xampp\php\php.exe
Just extending the answer by #Reinaldo Duguet with a ton of thanks to him !
If you are using Xampp, the PHP path can be found by running the local server and then typing localhost in the browser. This will open the Xampp dashboard. Click on phpinfo() and there you will get the exact path shown as
Configuration File (php.ini) Path = /opt/lampp/etc
Please note that the path may very as per the PHP installation in your system. So you may have to use the respective path shown with above ways.
Then, to let VSCode know this path, open settings in VSCode and search for "PHP debug" and click on the PHP > Debug:Executable Path setting
Add the following line at the first place after "{" telling VSCode where PHP is installed in the system.
"php.validate.executablePath": "/opt/lampp/etc",
If you are using Xampp, the PHP path can be found by running the local server and then typing
the correct version C:/xampp/php/php.exe
XAMPP isn't the best option for linux and i wouldn't recommend it.
Assuming this is not the problem, here is how to do :
find php executable
whereis php
Check your vscode installation. You want to make sure it's not using flatpak (it runs in a container and it would mess up everything)
go in vscode settings, search for php and set "php.debug.executablePath": "/your path/php"
If it still doesn't work, this might be a permission problem. Then :
copy the php executable in your user folder
sudo cp original_path/php /your_user_folder/php
add permissions
sudo chmod 777 /your_user_folder/php
If none of above worked, at this point, you may want to use a VM.
I just wanted to add a possibility here that ended up being my issue in case it helps someone else in the future. My issue was that I was using a Debian based distro and installed VSCode through the software app which relies on Snap apparently. Snap runs the programs in a sandbox and prevents them from seeing other locations on the computer. My solution was that I uninstalled the shop version and installed VScode manually via downloading directly from the website. After that, everything works as expected.

Php commands are not outputing result in windows

I have wamp install on my computer and IIS. All the websites are running well but then any command I type using php is not working :
php -v
php composer install
I would say it is the path variable (I am on windows) but the path is set correctly and it would generate an error of not finding php command. When I run those command I simply don't get any result.
What might be the problem, I am still searching but have not found any clue.
php -h
: return result with all the help information but php -a does nothing too.
After doing some research I found that this problem happens when I activate an extension by remove ; in php.ini whenever I leave php.ini without activating any extension everything works.
Check if the path contains php, also using the cd command, move to the location of the file and run the command you want to execute. If it works, you're sure the problem is the windows path.
I have fixed the issue. To see if the problem was with php.ini, I replaced the content of my php.ini with the php.ini-production file which made the php function well but almost all the extensions were desactivated.
As I was analysing I noticed wamp had many php extensions activated but in my php.ini residing under C:\wamp64\bin\php\php7.3.5 none of these extensions were activated following the path the file used by wamp I found it was using the phpForApache.ini via a link php.ini file inside C:\wamp64\bin\apache\apache2.4.39\bin
Since the wamp php configuration was working well, I just copied the content of that phpFOrApache.ini content in my php.ini after saving ... everything started working.

Why is PHP not recognizing a program in the Windows System PATH when I use it with Apache?

In my local development environment, I have Apache and PHP installed on Windows 7. I'm calling 7-Zip from my PHP program with exec. I tried at first with
exec('7z a example.zip example.pdf');
but it didn't create the zip file. After checking the Apache error log, I found
'7z' is not recognized as an internal or external command, operable program or batch file.
After changing the exec to include the full path to 7-Zip.exe, it worked.
exec('"C:\\Program Files\\7-Zip\\7z" a example.zip example.pdf');
But C:\Program Files\7-Zip is included in my Windows system PATH. The same PHP code works from the command line without using the full path.
php -r "exec('7z a example.zip example.pdf');"
Why is it requiring the full path when I use it with Apache?
An important point which I neglected to include when I originally posted this question is that I am already able to use exec() to call other programs included in the Windows System PATH without referring to them by their full paths.
Another point which I did not mention originally because I did not realize its relevance was that 7-Zip had been added to the PATH only recently, and I had restarted the Apache service after adding it.
I've WAMP installed on windows 8 and after reading your question I decided to test a couple of things.
Running echo exec('whoami'); echoed:
nt authority\system
This confirms what #Barmar said, Apache isn't running under the same user as you, so, the PATH is different.
I decided to stop Apache and start it manually under the Administrator account.
Then I tried:
echo exec('whoami');
Which outputted:
computername\administrator
I assumed that now the exec would work with PATH and tried:
echo exec('adb'); //android adb tool is on my PATH
Surprisingly, despite the fact Apache was running with the same user as me, the PATH still didn't work. I've no idea why this is happening and if someone has a clue please comment below.
I managed to use the PATH (using the Administrator account) with the following code:
https://stackoverflow.com/users/171318/hek2mgl
$WshShell = new COM("WScript.Shell");
$oExec = $WshShell->Run("cmd /C 7z a example.zip example.pdf", 0); // 0 invisible / 1 visible
I didn't test the code below, but you can try setting the PATH under the Apache Service account (nt authority\system), and then use the command, i.e.:
echo exec('set PATH=%PATH%;C:/path/to/7z');
echo exec('7z a example.zip example.pdf');
I believe the path will still be valid between restarts.
Update:
this answer, may help you setting the PATH for the account nt authority\system.
The Local System user's personal environment variables are specified
at "HKEY_USERS.DEFAULT\Environment". The machine-wide environment
variables are specified at
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Environment". The former isn't really easily accessible from
anywhere except the registry, but the latter is accessible from the
"Environment Variables" dialog on the "Advanced" tab of the "System
Properties".
For future users, the correct way to set the Apache PATH is:
You can use setEnv in .htaccess or putenv in PHP code to set
$PATH

I just figured out what was causing this problem. It was actually unrelated to my original assumption.
I remembered seeing PATH information in phpinfo(), so I looked at that. In the "Apache Environment" section it did show all of the PATH except the path to 7-Zip, which I had just added to the system PATH recently. So apparently it DOES seem to have access to that path, but it wasn't using the current version of it. Why not?
Normally I would think I had just forgotten to restart Apache after updating the path, but I'd restarted it repeatedly while trying to figure this out. But apparently restarting Apache does not refresh this value. I had to stop it and then start it. Then the 7-Zip path showed up in PATH in phpinfo, and I was able to change my program back to using plain 7z.

PHP error when i use Webception and wamp server

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/

php error : php command not found

My system is win7. I have installed XAMPP on the system successfully.Besides, I have set the environment variables:
PHP_HOME=C:\xampp\php
Path=%PHP_HOME%
But when i run php code in git bash ,it appears the error:"sh.exe:php:command not found"
How can i solve the problem?
In my case I can solved my problem in this way ...
Go to PHP directory in the XAMPP folder and run the code in this way with the XAMPP server:
$ Php /c/xampp/htdocs/cupon/bin/vendors install
As far as i was trying to execute MSVC compiler from within Java, i got the idea of all that Win7: the shell you are running something has different environment variables that you think you've set.
I recommend you to insall WAMP server - it is totally compatible with Windows while XAMPP seems to be a bit hard way to start with.
And one more hint: try running php / sh from the bin/ PHP directory.
If you're using Windows and getting the "php: command not found" error, it means that the PHP executable is not in your system's PATH environment variable. Here are the steps to fix it:
Find the location of your PHP installation. By default, PHP is installed in the "C:\php" directory. If you've installed PHP in a different location, note down that path.
Add the PHP directory to the system's PATH environment variable:
Open the Start menu and search for "Environment Variables."
Click on "Edit the system environment variables."
Click on the "Environment Variables" button at the bottom of the window.
Under "System Variables," scroll down and find the "Path" variable. Click "Edit."
Click "New" and enter the path to your PHP directory (e.g., "C:\php").
Click "OK" to close all the windows.
Close and reopen your terminal or command prompt to apply the changes.
Verify that PHP is working by running the command "php -v" in your terminal or command prompt. You should see the version of PHP installed on your system.
If PHP is still not working after following these steps, you may need to reinstall PHP or check that the PHP executable file is in the correct directory.
