我想在同一个文件中获取用户输入并用于某些操作。
echo '<Say>Please enter the number followed by hash key..</Say>';
echo '< Gather '.$number1 = (int) $_REQUEST['Digits'].'> </Gather>' ;
echo '<Say>Enter the secod number followed by the hash key...</Say>';
echo '< Gather '. $number2 = (int) $_REQUEST['Digits'].'> </Gather>' ;
$sum = $number1 + number2
echo ' $sum';
这是使用Gather的正确方法吗?
