Php command line

Question

Using Python I can test my code in the terminal / command line by typing

python 
python> print "hello world"

I would also like to do this with PHP, but on input:

php
echo "hello world";

he does not work. Is it possible? what should I do? A quick search on the Internet gives a lot of results that cause the actual .php file to run. I want to check only one sentence, if possible, without creating files, etc.
