Rowan Tommins ede9d209f6 Clarify the syntax and role of arguments for echo and print
- Rather than implying that parentheses are optional, make clear
  that they are never part of the syntax for these keywords.
- Don't spend so many examples on different types of string.
- Do include examples of non-string arguments.
- Add a note with additional examples of how parentheses interact.
- Don't refer to either construct as "function-like", instead use
  the term "expression" consistently.
- Additional tidying to make the pages more consistent with each
  other.
- Add "print" to the list of language constructs which are
  documented as functions.
- Remove mention of what PHP versions below 5.4 did with short
  echo tags.

Any PHP script is built out of a series of statements. A statement
can be an assignment, a function call, a loop, a conditional
statement or even a statement that does nothing (an empty
statement). Statements usually end with a semicolon. In addition,
statements can be grouped into a statement-group by encapsulating a
group of statements with curly braces. A statement-group is a
statement by itself as well. The various statement types are
described in this chapter.
