I'm writing a php cli interactive program, it act as a shell by using readline extension.
But I find that when I press Ctrl + C, the whole program exits. I hope it can get a new prompt instead of exit (just like bash).
So I try pcntl_signal to handle the SIGINT
pcntl_signal(SIGINT, SIG_IGN);
It doesn't exit and response nothing (just like dead)
I change the code to:
pcntl_signal(SIGINT, function(){
echo "\n";
});
这次它打印^C但没有新行，当我按下Enter这些时，提示之前是一个新行。 …
