Opening Brace in Function Declarations

Function declarations follow the "Kernighan/Ritchie style". The function brace is on the same line as the function declaration. One space is required between the closing parenthesis and the brace.

Valid: brace on same line

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

Invalid: brace on next line

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