1. 建立一個二維陣列將該陣列處理成以下格式（5分）

（原圖）

(效果圖)

$subject = [
    ['name' => '語文', 'label' => '2'],
    ['name' => '數學', 'label' => '0'],
    ['name' => '化學', 'label' => '0'],
    ['name' => '英語', 'label' => '0'],
    ['name' => '政治', 'label' => '2'],
    ['name' => '繪畫', 'label
 
' => '1'],
    ['name' => '攝影', 'label' => '1'],
];
$subjectDate = [
    '0' => '理科',
    '1' => '藝術',
    '2' => '文科'
];
$result=[];
foreach ($subject as $k=>$v){
    $label=$v['label'];
  $name=$subjectDate[$label];
$result[$name][]=$v['name'];

}
//print_r($result);

（2）：

如圖json字串轉化成陣列且處理成以下格式（5分）

{"type_name":"電腦","spec":[{"name":"顏色","value":["紅色","黑色","藍色"]},{"name":"記憶體","value":["64G","256G"]}],"attr":[{"name":"毛重","value":"10g"},{"name":"產地","value":"北京"}]}

(原圖)

（效果圖）

$json='{"type_name":"電腦","spec":[{"name":"顏色","value":["紅色","黑色","藍色"]},{"name":"記憶體","value":["64G","256G"]}],"attr":[{"name":"毛重","value":"10g"},{"name":"產地","value":"北京"}]}
 
';
 $new_json=json_decode($json,true);
$arr=[];
foreach ($new_json['spec'][0]['value'] as $k=>$v){
    $arr[$k]['type_name']=$new_json['type_name'];
    $arr[$k]['color']=$v;
}
print_r($arr);
