limit execution time of shell_exec
fatal-error, php, shell-exec
Solution
You can't do this from within PHP - `set_time_limit()` is only checked after each PHP statement gets executed. Under linux you'd use `ulimit`, but it looks like you're using Windows.
You'll need to either modify the `hello.exe` executable to build in a timeout, or write a wrapper that you call from PHP, which call `hello.exe` and handles the timeout. In any language that can easily fork, this is trivial.
Problem
I have an exe file which has the following code: while(1) printf("hello\n"); I'm executing this exe through php using shell_exec $output = shell_exec('C:/Users/thekosmix/Desktop/hello.exe 2>&1'); echo $output; now the script is executing for very long time untill i kill the process from task manager and it gives fatal error: (Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 133693440 bytes) in C:\xampp\htdocs\shell\index.php on line 7) I want the script (or this function) to run for a given time duration and print whatever output is generated during the time-duration not any fatal error. set_time_limit() is also not solving the problem.
