note 78672 added to features.commandline

I was looking for a way to interactively get a single
character response from user. Using STDIN with fread, fgets
and such will only work after pressing enter. So I came up
with this instead:

#!/usr/bin/php -q
<?php
function inKey($vals) {
	$inKey = "";
	While(!in_array($inKey,$vals)) {
		$inKey = trim(`read -s -n1 valu;echo $valu`);
	}
	return $inKey;
}
function echoAT($Row,$Col,$prompt="") {
	// Display prompt at specific screen coords
	echo
"33[".$Row.";".$Col."H".$pro
mpt;
}
	// Display prompt at position 10,10
	echoAT(10,10,"Opt : ");

	// Define acceptable responses
	$options =
array("1","2","3","4"
;,"X");

	// Get user response
	$key = inKey($options);

	// Display user response & exit
	echoAT(12,10,"Pressed : $keyn);
?>

Hope this helps someone.
