How to execute in PHP interactive mode
提问by Abhishek Mhatre
I am new to PHP, and I just wanted to run PHP in a command prompt (interactive mode).
我是 PHP 新手，我只想在命令提示符（交互模式）中运行 PHP。
So I typed this code:
所以我输入了这个代码：
`php -v`
`<?php`
`echo 7;`
`?>`
But I do not know how to execute it, because when I press Entercmd expects me to continue writing the code. I searched on php.net and some other forums, but I didn't find anything. So is there a function key or something to display the result?
但我不知道如何执行它，因为当我按下Entercmd时，我希望我继续编写代码。我在 php.net 和其他一些论坛上搜索过，但没有找到任何东西。那么是否有功能键或其他东西来显示结果？

Ctrl+dwill trigger an end-of-file condition and cause the script to be executed.
Ctrl+d将触发文件结束条件并导致脚本被执行。

Interactive Shell and Interactive Mode are not the same thing, despite the similar names and functionality.
If you type php -a and get a response of 'Interactive Shell' followed by a php> prompt, you have interactive shell available (PHP was compiled with readline support). If instead you get a response of 'Interactive mode enabled', you DO NOT have interactive shell available and this article does not apply to you.
So if you get only "Interactive mode enabled", then you'll only be able to type in PHP code and then when you're done, send PHP an EOF to execute it.
尽管名称和功能相似，但 Interactive Shell 和 Interactive Mode 并不是一回事。
如果您键入 php -a 并得到“Interactive Shell”的响应，然后是 php> 提示，则您有可用的交互式 shell（PHP 是使用 readline 支持编译的）。相反，如果您收到“启用交互模式”的响应，则您没有可用的交互式 shell，本文不适用于您。
因此，如果您只获得“启用交互模式”，那么您将只能输入 PHP 代码，然后当您完成后，向 PHP 发送一个 EOF 以执行它。
"EOF" means "end-of-file".
“EOF”的意思是“文件结尾”。

If following your command with Ctrl+ Disn't working, you probably don't have Interactive Shell(which apparently gives input after each line). That requires compiling phpwith special options. But if php -asays interactive mode, you can type directly into it and send Ctrl+ Zat the end of the file.
如果用Ctrl+跟随你的命令D不起作用，你可能没有Interactive Shell（这显然在每一行之后给出输入）。这需要php使用特殊选项进行编译。但是如果php -a说interactive mode，您可以直接输入并在文件末尾发送Ctrl+ Z。
php -a
interactive mode enabled
<?php
echo "hello there world!";
phpinfo();
?>
^Z
(Hit enter)
（命中enter）
hello there world!
phpinfo....
