I have windows batch file and also its scheduled in task scheduler.
task schedule working fine but the windows batch file does not execute
its in an php file. I am learning php and the windows batch file was coded previous employee.
The below code which i took from inside the windows batch file.
The path is correct , what is the purpose of - f ? and can you correct me the code.
List of commandline options can be found here http://php.net/manual/en/features.commandline.options.php
in your case -f stands for Parse and execute File
Change your batch to something like this:
#ECHO ON
echo Before php %TIME% %DATE% >> C:\temp\task.log
C:
Cd \www2
C:\PHP5.3\php.exe -f "C:\www2\cron.php" >> C:\temp\task.log
echo After php %TIME% %DATE% >> C:\temp\task.log
As long as you have the echo command and the call of the php interpreter on a single line this only output a meaningless text to the screen.
The first echo is there to help you diagnose problems: if the scheduled tasks is being called you will see this logged in task.log.
To make sure that the working directory is set to C:\www2 (cron.php will look for files there unless they get addressed with a full path) we change to that directory before running php.
In case php prints any error messages or information we redirect that output to the same log because otherwise you will not see this. You should delete that log from time to time because it can grow considerably. It is up to you to decide which of the logging statements you want to keep or remove ;-)
You can even have the log roll over by size, I bet there are question here on SO that will show you how this can be done ;-)

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
2 part question,
I am running a script that executes a second script.
I have it setup this way because I read if I put a script in the /etc/init.d directory it will run it at start up.(true or false?)
I have tried adding >> LoopTriggerLogging.log at the end of each line but nothing comes out in the log file
So I have a first script as follows
#!/bin/bash
/var/www/Dev/LoopTrigger.sh
exit
This triggers the following script to run
#!/bin/bash
while true; do
# do some work
php /var/www/Dev/FindNearestDriverAndSendPush.php
php /var/www/Dev/ProcessCustomerPayment.php
php /var/www/Dev/ProcessDriversPayment.php
# write to LoopTriggerLogging.log
sleep 2 # sleep and repeat
done
What I would like is to have the commands logged along with any errors. I have tried to read a little on this but get lost in the answers and what they are trying to tell the user. I am still new at this and learning, kindly give definition to any commands or options. I am open to a best practice scenario.
Also, with putting in the etc/init.d directory will this tell the script to run at start up?
Is there a way to run this script without it taking up the command line because its an endless script?
My ultimate goal is to get the 3 php files to execute every 2 seconds with some sort of logging.
I did some reading on Cron but seems it is not meant for this type of use case.
Ive also seen this:
exec > logfile 2>&1 (dont know what this does)
set -x makes bash print every command before executing it
FOO=BAR (dont know what this means)
echo $FOO (dont know what this means)
if I put a script in the /etc/init.d directory it will run it at start
up.(true or false)
True. If you put a script in init.d then that script will run for every startup.
My ultimate goal is to get the 3 php files to execute every 2 seconds
You are using the correct way of running it approx every 2sec depending upon the time your php script takes to run. Crontab runs after a minimum of one minute so that would not an option.
I have tried adding >> LoopTriggerLogging.log at the end of each line
but nothing comes out in the log file
You can use /var/www/Dev/LoopTrigger.sh >> LoopTriggerLogging.log in your first script so that whenever it runs it will
Create a file for the first time and append the content from the next time.
Push all the logs of the second script into the file.
Note: As logs will keep on appending to the single file, this file will become very huge at some point of time so make sure your handle it well.
I've created a service with reactphp which runs and does some stuff. It is started as a daemon so all output should be logged in a file.
This log file should be named 'foo-log-file-$(date "+F")'. I want to have a single log file for each day.
Problem:
As mentioned the script runs as a service, without stopping. The starting call for the script is therefore only done once.
php my_script.php >> /var/log/bar/log-file--$(date "+%F") 2>&1
So everything which is printed to the console from this script is saved into the file, but the file is only created with the date-string when it was called and is not updated with a new date.
Question:
Is it possible to solve this without writing the log logic in the php-script? Can i handle this requirement with bash?
FYI
The answer of #fedorqui was a good approach, i solved it with a cronjob, which copies the file to a different one and empties the rest.
You cannot use move, cause the through the running service, it is open all time and you get the error:
cannot move 'foo.log' to 'bar.log': Text file busy
So i cp it and clear the old one with:
cp foo.log foo.log.$(date +"%F");
cp /dev/null file.log;
I have two php files. In one php file there is simple html form in which I created some drop down for select time and days for cronjob when user set time and day and submit form then all the drop down values stored in database.
Now with the help of this stored values I need to set cronjob and when cron will execute then it run another php file in which I write some code for generate xml file.
And this file run every time which time is stored by user in database.
By using Cpanel I can do that but I don't want to use cpanel.
Please give me some proper and working solution, I really need it.
Thanks in advance.
Use phps system() or exec() function to call the crontab command to replace or modify the existing crontab for the account the web server runs under. You might have to make sure that user is allowed to use the cron system, this depends on the operating system you use.
From within the crontab you can use one of two strategies to run a php script_
- call the php cli interpreter like any normal command, so something like: /usr/bin/php and give it the script to interpret. As an alternative you also can use shebang inside your php script and call it as a simple executable.
- use wget to call an url pointing to your webserver (maybe localhost) when you want to execute the script inside your web server.
This might act as a starting point for you to experiment with:
#!/usr/bin/php
<?php
// the time tokens to be fed into the crontab line
$time=array('10','*','*','*','*');
// the actual command to be executed
$command=sprintf("crontab -l | (cat;echo \"%s\t%s\") | crontab",
implode(' ',$time),
'/usr/bin/beep');
// execute command
$result=system($command);
// output result of execution
if ($result)
echo "Result: $result\n";
else
echo "FAILURE!\n";
?>
Works for me when called from CLI.
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?
