HHVM readline() function requires a parameter see:
https://github.com/facebook/hhvm/blob/master/hphp/runtime/ext/readline/ext_readline.php
But the php readline does not require one.
```
In Symfony\Component\Console\Helper\QuestionHelper
…
readFromInput($stream)
…
```
we use readline() without a parameter.
HHVM Version:
```
HipHop VM 3.10.1 (rel)
Compiler: tags/HHVM-3.10.1-0-g689b4969a141620ee5a282ce0dbf72278c84d44b
Repo schema: 6c99ee1f98340f6f3ef397a332583f0e843a627d
```
Docker Container:
```
docker run --rm -it -v `pwd`:`pwd` -w `pwd` brunoric/hhvm:deb hhvm test.php ls
```
Test.php
```
<?php
use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Question\Question;
use Symfony\Component\Console\Helper\QuestionHelper;
require_once "vendor/autoload.php";
$console = new Application();
$console
->register('ls')
->setDescription('Try input')
->setCode(function (InputInterface $input, OutputInterface $output) {
$question = new Question('Your email address: ');
$question->setValidator(
function ($answer) {
return $answer;
}
);
$question->setMaxAttempts(5);
$helper = new QuestionHelper();
$email = $helper->ask($input, $output, $question);
$output->writeln(sprintf('Email Adress: <info>%s</info>', $email));
})
;
$console->run();
```
composer.json
```
{
"require": {
"symfony/console": "^3.0"
}
}
```
Result:
No input is possible and you got a warning
```
Your email address:
Warning: readline() expects exactly 1 parameter, 0 given in /clitest/vendor/symfony/console/Helper/QuestionHelper.php on line 436
Email Adress:
```
Fix:
Add a empty string parameter to readline() or use fgets() for hhvm.
