It's an interesting problem. I've came up with this proof of concept:

function format_phone_number($number){
$formats = array(
5 => "### ##",
6 => "## ## ##",
7 => "### ## ##"
);

$len = strlen($number);

if( isset($formats[$len]) ){
$format = strtr($formats[$len], array('#' => '%s'));
$digits = str_split($number);
return vsprintf($format, $digits);
}else{
return $number;
}
}

Basically, it converts your expression into a printf-compatible format.

Of course, it'd be easier to use such expression from the beginning:

function format_phone_number($number){
$formats = array(
5 => "%s%s%s %s%s",
6 => "%s%s %s%s %s%s",
7 => "%s%s%s %s%s %s%s"
);

$len = strlen($number);

if( isset($formats[$len]) ){
$digits = str_split($number);
return vsprintf($formats[$len], $digits);
}else{
return $number;
}
}

You could replace %s with %d if you validate that $number is an integer.
