Opening Brace in Function Declarations

Function declarations follow the "BSD/Allman style". The function brace is on the line following the function declaration and is indented to the same column as the start of the function declaration.

Valid: brace on next line

function fooFunction($arg1, $arg2 = '') <em>{</em> ... }

Invalid: brace on same line

function fooFunction($arg1, $arg2 = '') <em>{</em> ... }
