我需要创建一个 while/loop 来获取单独的电子邮件数据，我也尝试过

$obj = json_decode( file_get_contents( 'php://input' ) );
foreach ($obj as $value) {    
   $value->email;
}

但它始终仅返回第一个或最后一个值

Answer 1

如果您知道数组键，这应该对您有用，并且它消除了双循环。

$array = json_decode(file_get_contents( 'php://input' ), true);
foreach($array as $innerArray){
    $emails[] = $innerArray['email'];
    //or do whatever you want with each email as $innerArray['email'], repeat for each key.
}
