------解决方案--------------------

$str = 'tmap 116.123456,39.123456';
preg_match_all('/[^\s]+/', $str, $match);
$numstr = $match[0][1];
print_r(explode(',',$numstr));


Array
(
[0] => 116.123456
[1] => 39.123456
)

------解决方案--------------------
$s = 'tmap 116.123456,39.123456';
preg_match_all('/[\d.]+/', $s, $r);
print_r($r[0]);
