Based on this manual, there is a
-r option that allows you to run PHP code on the command line without specifying the code tags,
I recommended it on the polyquine question, where this answer code be considered a PHP quine if we used
-R. I'm pretty sure
-R is used like
php -R scriptname.php or something and then runs the script like it is in between code tags.
Coming from a Perl background, one-liners are often used to shorten the code. My answer here is an example. The way we have been counting it for Perl one-liners are:
- Each characters between the single quotes counts as a character.
- Each additional flag counts as a character.
^ under each character we count for the following one-liner just as an example:
echo "test" | perl -nle'print' ^^ ^^^^^
which would count as 7 characters.
For PHP, can we do the same thing? For example in this program from that manual:
$ php -r '$foo = get_defined_constants(); var_dump($foo);'
We would count the characters in between
I think you'd be able to shorten this answer with the trick.
There was a small discussion in the comments here about it.
- Would the
-rcount as 0, 1, or 2 characters?
- Is this allowed?
- Should I recommend this when I see answers with
I am not the best at PHP so I'm looking for some guidance.
