関数宣言は、以下のような "K&R スタイル"にしたがいます。
<?php
function fooFunction($arg1, $arg2 = '')
{
if (condition) {
statement;
}
return $val;
}
?>
|
デフォルト値を有する引数は、引数リストの終わりに置きます。
適切でない場合を除き、関数は、意味のある値を返すようにします。
やや長い例を示します。
<?php
function connect(&$dsn, $persistent = false)
{
if (is_array($dsn)) {
$dsninfo = &$dsn;
} else {
$dsninfo = DB::parseDSN($dsn);
}
if (!$dsninfo || !$dsninfo['phptype']) {
return $this->raiseError();
}
return true;
}
?>

Note to previous post: the Allman style is not only used for functions but also for class definitions.
Note by: pear at alan hogan dot com
Allman style is defined here for those unfamiliar with it:
http://en.wikipedia.org/wiki/Indent_style
Please note that the PEAR coding standards *do not* follow Allman style for *control structures*, only for functions.
Note by: pear at alan hogan dot com
Again according to Wikipedia, it would seem that PEAR, in fact, advocates K&R style:
function foo ()
{
//do stuff();
}
while (true) {
if (true ) {
//x..
}
}
It should be noted that both Allman and K&R agree on how to format function definitions.
