How should this program be written

The method is a bit stupid, but it can achieve the effect you want. I hope it can help you. The code is as follows: public function index() { $array = [0.6, 0.7, 1, 0, -1, -2, -3, 0, 0, -1, -5, -6, 1, 3, 4]; $result = []; foreach ($array as $value) { $count = count($result); if ($count > 0) { $single = $result[$count - 1]; $index = end($single); if (0 === $index) { if (0 === $value) { $result = $this->handleArray($result, $single, $value, $count); } else { $result = $this->handleArrayTwo($result, $value); } } elseif ($index > 0) { if ($value handleArrayTwo($result, $value); } else { $result = $this->handleArray($result, $single, $value, $count); } } elseif ($index < 0) { if ($value >= 0) { $result = $this->handleArrayTwo($result, $value); } else { $result = $this->handleArray($result, $single, $value, $count); } } } else { $result = $this->handleArrayTwo($result, $value); } } var_dump($result); die; } private function handleArray($result, $single, $value, $index) { unset($result[$index - 1]); array_push($single, $value); array_push($result, $single); return array_values($result); } private function handleArrayTwo($result, $value) { $array = []; array_push($array, $value); array_push($result, $array); return $result; } // array(6) { //[0]=> // array(3) { //[0]=> // float(0.6) //[1]=> // float(0.7) //[2]=> // int(1) // } //[1]=> // array(1) { //[0]=> // int(0) // } //[2]=> // array(3) { //[0]=> // int(-1) //[1]=> // int(-2) //[2]=> // int(-3) // } //[3]=> // array(2) { //[0]=> // int(0) //[1]=> // int(0) // } //[4]=> // array(3) { //[0]=> // int(-1) //[1]=> // int(-5) //[2]=> // int(-6) // } //[5]=> // array(3) { //[0]=> // int(1) //[1]=> // int(3) //[2]=> // int(4) // } //}
