Windows Solution
视窗解决方案
in windows there is no interactive mode same as Linux cause windows can't read lines from command line, but still can use interactive like mode!, so on windows open php on place you installed it for example if you use xampp php is on C:\xampp\phpand then type php -alike what you type in terminal but on end of each part you want to view the results just press Ctrl+Zand then Press enter.
在窗户那里，Linux的原因Windows不能读取命令行线，但仍然可以安装它，例如，如果你用的是XAMPP PHP是对地方采用互动模式一样！所以在Windows中打开PHP是无交互模式相同C:\xampp\php，并然后键入php -a您在终端中键入的内容，但在每个部分的末尾，您要查看结果只需按Ctrl+Z然后按 Enter。
php -a
echo 'hello world!';

Escape the inside double quotes (") that you are using to delimit your string.
转义"用于分隔字符串的内部双引号 ( )。
php -r "Print \"Hello, World!\";"
Alternatively, use single quotes (') for the PHP string or for the quoting of the PHP code.
或者，'对 PHP 字符串或对 PHP 代码的引用使用单引号 ( )。
