note 99505 modified in ref.exec by danbrown

Within Linux, when calling the php interpreter directly from popen, or other program execution function to execute a script, it appears as though the script perpetually fails and re-executes. i.e. <?php popen("php myscript.php&", "w"); // fail ?> As each re-execution causes the executing script to load under a new PID, it is incredibly difficult to identify and kill the process manually. [One solution is] to ensure the executing script has a valid shebang, and execute permissions. This allows you to execute the script directly i.e. <?php popen("./myscript.php", "w"); // ok ?> --was-- Within Linux, when calling the php interpreter directly from popen, or other program execution function to execute a script, it appears as though the script perpetually fails and re-executes. i.e. popen("php myscript.php&", "w"); // fail As each re-execution causes the executing script to load under a new PID, it is incredibly difficult to identify and kill the process manually.
