ACK.

         Perhaps the most common of them is the echo statement, which allows

you to write data to the script’s output: echo 10; // will output 10 It’s important to understand that echo is not a function and, as such, it does not have a return value. If you need to output data through a function, you can use print() instead:

print is a language construct and not a function. Try e.g. call_user_func('print', 'foo'); However, it's interesting that print nonetheless has a return value (which always is 1).

One of the most popular constructs has a return value: isset.
