Asynchronous shell exec in PHP

i need to run a java program in the background.

process.php contains

shell_exec("php php_cli.php")

php_cli.php contains

shell_exec("java -jar BiForce.jar settings.ini > log.txt");

I am calling process.php asynchronously using ajax

When i click the link in the webpage that calls ajax function (for running process.php) the webage shows “loading”. when i click other links at the same time it does not responds.

The java program takes about 24 hours to finish executing, so user will not wait until the execution ends.

The problem is that the browser keeps on loading and does not go to other pages when clicked the link.

I also tried with system(), but the same problem ….

Help will greatly be appreciated.

Answer 1

You could call the command in the page displayed, but appending an & at the end:

shell_exec("java -jar BiForce.jar settings.ini > log.txt &");

This way the process is launched on the background.

Also, there is no need (unless defined by your application) to create a process.php wich itself calls php via a shell exec. You could archive the same functionality via an include to the other file.
