Stop executing PHP for or while loop in Command line with key press?

问题

Is it possible in php to exit a loop on a "key press"?

For example continual for loop to exit on key press and to continue executing rest of code so not sigterm, just stop loop and continue?

What you want to do is read from stdin: http://linux.about.com/library/cmd/blcmdl3_stdin.htm

Here's a tutorial for how to do it in PHP: http://codegolf.com/boards/conversation/view/129

Hope that helps!

Edit: Found a question which answered this much better: PHP CLI: How to read a single character of input from the TTY (without waiting for the enter key)?

Ctrl-C keystroke will stop the loop, I believe ;-)

for Windows, you can use API functions to retrieve keyboard state. The way to call Win32 API functions is described in http://de.php.net/manual/en/ref.w32api.php. The API function you need to call is GetKeyboardState where the result is stored in an array.
