What input functions can I use in TIO's PHP?
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.
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?
