I have a situation where I need to call a batch file from a php script... however this batch file needs to run as admin in order to work.
My solution was to create a shortcut to the batch file and check the box to run as admin from the shortcut... however I can't get php to call the shortcut.
I have tried:
exec("C:/path/movefiles_admin.lnk")
and
system("cmd /c C:/path/movefiles_admin.lnk");
Neither of which work. Any suggestions?
Try this:
exec("START C:/path/movefiles_admin.lnk");
START Starts a separate Command Prompt window to run a specified program or command.
You can run nonexecutable files through their file association by typing the name of the file as a command
If your PHP has issues executing shortcut to batch file, try executing simple read and write actions to a test.txt file. (To check whether you have PHP running in safe mode).
If it doesnt do these basic actions then you have some configuration issues.
If a program is started with exec function, in order for it to continue running in the background, the output of the program must be redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.
Please refer this link for your version of PHP: manual

I have 2 .php files in my application - book.php and weather.php. I create a file named "runscript" in /.openshift/cron/minutely. This file contents:
#!/bin/bash
php -f $OPENSHIFT_REPO_DIR/weather.php
This script send me message to phone every minute, it's OK.
Then I replace to:
php -f $OPENSHIFT_REPO_DIR/book.php
This script MUST send me message too, but nothing is happing. But if I just run this script by my webbrowser (go to the http://xxx-xxxxxxx.rhcloud.com/book.php) so I got my message. How is it possible? Magic?
Did you miss the #!/bin/bash part? That's needed to run the shell script.
For why your cron job is not executing, check the cron logs on OpenShift. You can find them at ~/app-root/logs/cron_*.log when you SSH into your gear.
Make sure your cron job is execuable with chmod, and has the shebang line as #gnaanaa says. Also check if you have one of the .openshift/cron/minutely/jobs.{allow,deny} files as they may cause cron to skip your job. (See the cron README for more information.)
And after your cron job is working, you can get rid of the wrapper script runscript and have cron call book.php directly. To do so, place book.php directly into .openshift/cron/minutely, make it executable, and add this shebang to it:
#!/usr/bin/env php
Hope this helps.
I use openshift aswell and executed a php file with a cron aswell.
#!/bin/bash
php ${OPENSHIFT_REPO_DIR}index.php
This executes the script normally at first sight. However no output was produced. The problem was, that all the required php files couldnt be loaded because the working directory was not the same as it would be when loaded by the webserver. Setting the working directoy in the php script itself will prevent this error and makes the script perfectly executable by the cron.
This should help some people to get their script running.
I currently use nohup to run a long php script and redirect the live results to a file using this command
nohup php long_file.php >logs 2>&1 &
so i just go and visit logs file continuously to see the results
Now i want to do the exact same thing using another php file to execute the above command
i tried the above command with php exec and the redirect output doesn't seem to be working,
I know i can just retrive the output using php and store it using any file write function but the thing is .. the output is too long thats why i keep it running on server's background
a similar question :
Shell_exec php with nohup, but it had no answer
any solution ?
Please try with -q
nohup php -q long_file.php >logs 2>&1 &

Did you try passthru instead of exec?
You are redirecting STDOUT to a file by using >
This will truncate the file each time the script is run. If two scripts simultaneously redirect their output to the same file, the one started last will truncate the output from the first script.
If you really want to properly append to a log file with multiple concurrent running scripts, consider using >> to avoid having the log file truncated.
Side effect however is that the log file never truncates and keeps expanding, so if the file gets really large you can consider including it in a logrotate scheme.
If i run shell_exec(php file) , will it activate the shell_execution and continue with the php file, or will it try to complete everything in the shell_executed php file first, then run the rest of the php file that executed it.
It will complete the shell execution first and then it will run rest of the code in the php file.
shell_exec(), as stated in the Documentation, will return the complete output as a string. So it has to be a "blocking" function. That means it will block the execution of the rest of your code until it is complete.
Depending on your command that you want to execute, you may want to force the process to run in the background with the & character at the end of the command. This is assuming ofcourse that you are running on a unix based server.
exec("fun.exe input/input.txt ");
I want to run an CUDA program in PHP,
the task is:
load data from an input.txt. (argument)
calculating.
write an output.txt.
and PHP read ouput.txt to do next task.
In server1(Apache ,Windows XP), it can run perfectly,
but in server2,3(Apache, Windows 7),the output is wrong.
The program doesn't crash and there's no any error message in the page,
it seems like something wrong during the execution.
Next I try exec the All CPU-side version (same calculation),server2,3 can run correctly.
If I exec the fun.exe(CUDA version) in server2,3 directly(double click or in command line),the program also run perfectly.
Any idea on why server2,3 can't run the program? Thanks.
First, try using the full path to the executable. Then the full path to the input file too.
If that doesn't work, then try modifying the file permissions (try with full 777 permissions, if that works then you know where your problem lies).
Try to use the entire path (windows version using backslash).
I am trying to run a shell script from a php script.
I have complete control of the environment (unix on mac), I should have all the permissions, etc. set correctly.
The web script is in /htdocs/
The shell script can be executed from anywhere so when I go to /htdocs/ in the shell, I can easily run it like this:
$ my_shellscript
.. but when my php script (which is located in htdocs) tries to call it:
shell_exec('my_shellscript');
I get nothing.
I have proven the script can be called from that location and I have temporarily granted full access to try to get it working somehow. I am going crazy, please help.
If you know of some other way of triggering a shell script via the web that would be fine.
Thanks in advance.
well i got few weeks same problem, the solution is to check if the apace has the permission to execute your script. You could also try to run the script in php cli.
Since it is a shellscript, it needs to be invoked with the path prefix. My guess is you need to do this:
shell_exec('./my_shellscript');
First thing: make sure php isn't running in Safe Mode
Next thing: Try running it with the exec() function and using the full path (e.g. /var/www/htdocs/my_shellscript)
Try doing
echo shell_exec('my_shellscript 2>&1');
which will capture the script's stderr output and print it out. If something inside the script is failing, this output would otherwise be lost when not being run interactively.
