| 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. |
In other words, the following code is valid PHP code:
echo 'Hello World';
{ //polite stuff
echo ", it's nice to meet you.\n";
echo "May I be of service?\n";
}
|
The curly braces define a statement group similar to when used with if, else, foreach, etc. It does not create a new variable scope, but can be used to format/organize code in some arbitrary way. Statement groups can contain almost anything (assuming nest conventions are followed). Some things that can't be used inside statement blocks are:
namespace,
use, (global)
const, and
__halt_compiler().
Anything in curly braces will have a fold mark in PhpED. That includes statement groups which then function just as one would hope/expect. One feature that would be nice is if PhpED showed the comment immediately after the starting brace while the group is folded. One can even make a shortcut to create a foldable statement group using code snippets in PhpED. For example, the following template could be created and assigned to the keyboard combination
Ctrl+Alt+B
{// my_custom_code_block
|} |
Thereafter one could highlight a block of code then hit
Ctrl+Alt+B to wrap the highlighted statements in curly braces, creating a statement group.
