You may find ncurses_getch() of use however. http://www.php.net/ncurses_getch -- Greg Donald I'm not sure how great this solution is but here it is anyway: exec(stty -icanon min 0 time 0); The -icanon turns of canonical reading of stdin. The min has to do with the minimum characters needed for a read to be complete while time sets the read timeout (0 means no timeout and no minimum characters). You can also turn off echo if you don't need the user to see what they type: exec(stty -icanon -echo min 0 time 0); If you do this and run your script it will affect your terminal. If you happen to turn echo off just hit Ctrl c (to clear any invisible commands) and type (blindly) stty echo to turn it back on. To see the current terminal options do stty or stty -a to see everything. man stty is just as much fun. :-) Good luck, Jim Grill -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
