****** Function Definitions ******

Function declarations follow the "K&R style": Arguments with default values go at the end of the argument list. Always attempt to return a meaningful value from a function if one is appropriate. Here is a slightly longer example: <?php function connect(&$dsn, $persistent = false) {     if (is_array($dsn)) {         $dsninfo = &$dsn;     } else {         $dsninfo = DB::parseDSN($dsn);     }

    if (!$dsninfo || !$dsninfo['phptype']) {
        return $this->raiseError();
    }

    return true;
}
?>

Split function definitions onto several lines

Functions with many parameters may need to be split onto several lines to keep the 80 characters/line limit. The first parameters may be put onto the same line as the function name if there is enough space. Subsequent parameters on following lines are to be indented 4 spaces. The closing parenthesis and the opening brace are to be put onto the next line, on the same indentation level as the "function" keyword. <?php

function someFunctionWithAVeryLongName
($firstParameter = 'something', $secondParameter = 'booooo',
    $third = null, $fourthParameter = false, $fifthParameter = 123.12,
    $sixthParam = true
) {
    //....
?>
