是否可以跟踪进程之间的调用？

Question

是否可以用Java语言创建函数，当我在主程序中通过在php函数中调用的终端中调用它来执行它时，它会打印“此程序由process1.php所调用的终端调用”？
process1.php：

<?php
    exec("java Tracing.java");
?>

Tracing.java：

public class Tracing {
   public void objective(){ /* the source of objective function */}
   public static void main(String[] args){
      new Tracing().objective(); // Output : this program is called by Terminal who is called in process1.php
   }
}
