Q&A What input functions can I use in TIO's PHP?

You could use fgets to read from STDIN. And to print the message, just use the short tag (<?= whatever, which is a shorthand to <?php echo whatever; ?>): <?='Hello, '.fgets(STDIN).'!'...

You could use [`fgets`](https://www.php.net/manual/en/function.fgets) to read from [`STDIN`](https://www.php.net/manual/en/wrappers.php.php).
And to print the message, just use the *short tag* (`<?= whatever`, which is a shorthand to `<?php echo whatever; ?>`):
```php
<?='Hello, '.fgets(STDIN).'!';
```

Of course you could also do:
```php
<?php
echo 'Hello, '.fgets(STDIN).'!';
```
~~There are also other options, such as `file_get_contents("php://stdin")` or `stream_get_contents(STDIN)`, but as you said you're code-golfing, I guess the first option would be preferable[^1].~~
[^1]: I'm not a code-golfer, so not sure if that's the shortest possible way.
