You can use this function to ask user to enter something.
<?php
function read ($length='255')
{
if (!isset ($GLOBALS['StdinPointer']))
{
$GLOBALS['StdinPointer'] = fopen ("php://stdin","r");
}
$line = fgets ($GLOBALS['StdinPointer'],$length);
return trim ($line);
}
// then
echo "Enter your name: ";
$name = read ();
echo "\nHello $name! Where you came from? ";
$where = read ();
echo "\nI see. $where is very good place.";
?>
