Parse piped email with PHP - php

Question

I have been trying to setup up a system with this functionality:
Send email to my server
Server pipes email to php script
Php script parses email getting subject and body
Get phone number from subject of email and send text with email body
I have found an email parser here: https://github.com/daniele-occhipinti/php-email-parser
I think I have setup it up correctly but I do not know how to test it besides just sending an email. But I cannot see what my script echos at that point. Also when I do send the email I know something is not working because the text does not send via twilio. What am I doing wrong?
Here is the code:
#!/usr/bin/php -q
<?php
require_once '../resources/Twilio/autoload.php';
use Twilio\Rest\Client;
require('config.php');
// Retrieve Email
require_once("../resources/PlancakeEmailParser.php");
$email = "php://stdin";
$emailParser = new PlancakeEmailParser(file_get_contents($email));
$subject = $emailParser->getSubject();
$text = $emailParser->getPlainBody();
$number = preg_replace('/[^0-9]/', '', $subject);
$phone = "+".$number;
// After this I send the message via Twilio

Answer 1

You are piping the input so you probably need to buffer the stream to ensure you have received all the data before you try and process it.
Something like this:
$dataIn = fopen('php://stdin', 'r');
if ($dataIn) {
$email = '';
while($line = fgets($dataIn)) {
$email .= $line;
}
fclose($dataIn);
}
