Batch File executed via PHP runs all commands as background processes

Question

I am having trouble with a batch file and executing it through PHP.

We have some node servers and Avaya CMS running on a server with restricted access.

The servers need restarting daily as they sometimes crash, so I created a batch file to shut down all cmd windows, node and avaya.

Then it opens all the node servers and avaya, kicks off an AHK script that logins into avaya, and finally launches a few avaya reports.

This all runs fine when I double click the batch file, or if I run it via Task Scheduler, however we now would like to be able to run it via a button click on a PHP page.

This is where I am running in to trouble.

From what I can see, when I click the button, the batch file runs, closes all node servers and thats it, or so I thought, at first.

Through some digging I have found that it is in fact executing the whole batch file, however it runs all the cmd windows and avaya as background processes, and I think this is where my problem lies.

AFAIK when executing batch files from PHP there is no way to have it open cmd, however I thought that the batch file itself would run the cmd windows and avaya in the foreground.

Is there a way to achieve this?

Code below in case it is needed.

PHP

$test = escapeshellcmd('C:\Windows\System32\cmd.exe /k 
"C:\wamp\www\batch_files\R - Wallboards Script"');
system($test);

)
)

Try to create scheduled task which fires imediately, that overides PHP default behavior of running code in background. Creating Windows task with PHP — Da-FyK

As one possible solution, consider separating the PHP that running as web application with the PHP that runs the batch file, and with some mechanism between them to communicate with each other. For example, the first PHP could insert a mysql table row with status 'SUBMIT-RESTART', and the second PHP could be run in windows task scheduler each 2 minutes that does :

query the mysql table whether there is a row with 'SUBMIT-RESTART' status
if there is such row, change the status into 'RESTARTING', and proceed to run the batch commands,
upon finishing, change the status into 'RESTART-DONE'

HI thank you for your suggestion. Just to confirm, the only difference would be that the PHP that runs the batch file would be a script run by a scheduled task every 2 mins?
