如何將來自特定數組鍵的所有值分配給 json 值。$cars = Array ( [0] => Array ( [category] => Most Selling [title] => BMW [price] => 20000 ) [1] => Array ( [category] => Most Selling [title] => Jeep [price] => 15000) [2] => Array ( [category] => Most Selling [title] => Lexus [price] => 18000 ) )foreach ( $cars as $car) { $data = [ 'model' => 'new', 'company' => $car['title'],];}$json = json_encode($data); 現在當我輸出 $json 我得到：{"model":"new","company":"Lexus"}為什么它沒有像這樣分配所有標題值？{"model":"new","company":"BMW, Jeep, Lexus"}

你不需要foreach循環。您可以使用implode和array_column
$data = [
'model' => 'new',
'company' => implode(', ',array_column($cars, 'title'))
];
echo $json = json_encode($data);

這應該會產生您需要的輸出。
$data = [
'model' => 'new',
'company' => '',
];
foreach ( $cars as $car) {
$data['company'] .= $car['title'] . ', ';
}
$data['company'] = substr($data['company'], 0, -2); // remove last comma and space
$json = json_encode($data);

$companyString = implode(', ', array_column($cars, 'title'));
$data = [
'model' => 'new',
'company' => $companyString
];
$json = json_encode($data);
