I'm running a third party script by using a wrapper class I've written which calls shell_exec()
and pipes into a file I parse later using php code. I should mention that this is working, but I am trying to enhance the functionality, having encountered a use case I hadn't thought of.
How is it best to manage timeout on shell_exec()? I was thinking of wrapping it in a try() catch()
but I'm not sure how to best handle the time component.
I've been reading a few questions on here relating to shell_exec()
and exec()
and it seems that by passing output params to exec()
you can get a return, but that does rely on the script finishing with a return status. Plus in my mini test page, I can't seem to get it to return any output!
The other option I thought about was using a modal dialog, with an ajax style spinner whilst the script it working, and setting a manual timeout in javascript. Which then gave the user a model dialog message about it failing/timeout and ending.
Are there any accepted methods for this use case?
My mini test, consisted of the following,
public $e_return = array();
public $e_status = '';
// Paths are absolute from /
public function execCheck($domain){
exec($this->ssl_check_path." -s ".$domain." -p 443 > ".$this->folder.$this->filename." 2>&1 &", &$this->e_return, &$this->e_status);
}
// Returns
Array
