完成工作的方法：

$var = "100 1-testB/10000 20000.100 200 2-testB/2/20000 20000.200 300 3-testB/30000 30000.3000";
$output = explode(' ', $var);
foreach ($output as $k => $v) {
  if (FALSE !== strpos($v, '.')) {unset($output[$k]);}
}
$output = implode(' ', $output);
echo $output;  // 100 1-testB/10000 200 2-testB/2/20000 300 3-testB/30000
