Function declaractions follow the "one true brace" convention:
function fooFunction($arg1, $arg2 = '')
{
if (condition) {
statement;
}
return $val;
}
|
Arguments with default values go at the end of the argument list. Always attempt to return a meaningful value from a function if one is appropriate. Here is a slightly longer example:
function connect(&$dsn, $persistent = false)
{
if (is_array($dsn)) {
$dsninfo = &$dsn;
} else {
$dsninfo = DB::parseDSN($dsn);
}
if (!$dsninfo || !$dsninfo['phptype']) {
return $this->raiseError();
}
return true;
}
