What input functions can I use in TIO's PHP?
Try It Online! is an online interpreter for many supported languages, including PHP. I'm trying to solve coding challenges using the language, specifically "Hello, {name}!".
In PHP, you can literally add text outside of the script (<?php ?>) and it will output, which is what I did in the codeblock below. Currently, I'm struggling finding the input function for PHP. readline() and fscanf() aren't options for TIO:
Hello, <?php
$a=readline();
echo $a;
?>!
I'm not giving up yet, because I know for a fact that someone knows how can I set prompt for the program. So... how?
Question: What input functions work in PHP running from TIO?

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).'!';
Of course you could also do:
<?php
echo 'Hello, '.fgets(STDIN).'!';
And there are also other functions you could use, 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].

I'm not a code-golfer, so not sure if that's the shortest possible way. ↩︎
