PHP coding specification (12)

6.1 simple statements

Each line contains at most one statement, for example:

$ Argv ++; // correct
$ Argc --; // correct
$ Argv ++; $ argc --; // Error

6.2 compound statements

A compound statement is a sequence of statements contained in braces, such as "{statement }". For example, the following sections.

-The statements included in the statement should be indented to one level than the compound statement.
-The left braces "{" should be at the end of the row where the composite statement starts. The right braces "}" should start a new row and be aligned with the first line of the composite statement.
-Braces can be used for all statements, including a single statement, as long as these statements are part of an if-else or for control structure. This makes it easy to add statements without worrying about introducing bugs due to missing brackets.
