回复讨论(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
)

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

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

$s='tmap 116.123456,39.123456';$ar = preg_split('/[\s,]+/',$s);print_r($ar);

$str = 'tmap 116.123456,39.123456';print_r(preg_split('/[\s,]/', $str));
