php回应elixir iex stdin(php echo to elixir iex stdin)

好吧，我知道我在这里做一些奇怪的事情，但我必须这样做。

所以我的elixir程序需要运行一个PHP脚本并从脚本中获取信息，但它永远不会进入。我可以手动运行php脚本，并且它工作正常。在脚本的底部它说：

echo $avar->getPUId();

所以它打印出来回应我的猜测。从命令行运行它时，我得到需要的数据：

C:\PHP>php.exe "-f" "C:\pap.php" "613b8859" 37a69912

但是，当我从iex运行它时，我什么也得不到：

iex(1)> System.cmd("C:\\PHP\\php.exe", ["-f", "C:\\pap.php", "613b8859"]) Terminate batch job (Y/N)? y

现在，如果我搞砸了文件名或PHP会给我一个错误的回应说：

iex(1)> System.cmd("C:\\PHP\\php.exe", ["-f", "C:\\pap321.php", "613b8859"]) {"Could not open input file: c:/pap123.php\n", 1} ...

所以我知道我可以与PHP交谈，并且可以通过错误回复给我，但回显并没有被我的elixir应用程序所捕获，而这个应用程序显然会调用它。有没有其他方法可以抓取数据，因为它是从PHP脚本中提取出来的？

ok, I know I'm doing something weird here but I gotta do it.

So my elixir program needs to run one PHP script and take the information from that script, but it never comes in. I can manually run the php script and it works fine. At the bottom of the script it says:

echo $avar->getPUId();

So it's printing it out to echo I guess. I get the data I need when I run it from a command line:

C:\PHP>php.exe "-f" "C:\pap.php" "613b8859" 37a69912

But when I run it from iex I get nothing:

iex(1)> System.cmd("C:\\PHP\\php.exe", ["-f", "C:\\pap.php", "613b8859"]) Terminate batch job (Y/N)? y

Now, if I mess up on the filename or something php will give me an error in response saying like:

iex(1)> System.cmd("C:\\PHP\\php.exe", ["-f", "C:\\pap321.php", "613b8859"]) {"Could not open input file: c:/pap123.php\n", 1} ...

so I know I can talk to PHP, and it can talk back to me with errors, but echo isn't caught by my elixir application that calls it apparently. Is there any other way I can grab the data as it comes out of the PHP script?
