to software development and have got stuck. Please post your problems

Hi,

I ran into this problem.

I am planning to run a java program from a php script. The code for
that is

<?php
$output = shell_exec("java filename");
?>

shell_exec runs a command from the command line and stores the output
unto $output.

Now i want to terminate the program if its taking too long to execute
itself, for example more than 10 seconds or so.

Can anyone suggest how can I do this?

I solved the problem with the help of java itself. I made a java
program which takes in the name and inputs of the original program as
command line arguments. Then I started two threads, one calculating
the time elapsed and other running the original program. Thus i could
check whether the stipulated amount of time has expired or not.

I ran this java program from a php script but initially it was not
working as the php script was ignoring outputs which took too long.
After a lot of googling i found out that you needed to increase the
script execution time.

Change the following property in php.ini file

max_execution_time = 30; // accordingly

Now the script works fine.

If anyone made any other progress regarding this please share your
views.
