从php中的for循环推送关联数组

for 循环应该循环 10 次。 当我刚刚打印$fname, $lname and $email我正在获取 10 条数据（工作正常）

但我需要将这些值存储在关联数组中。

$assocDataArray = array();
foreach ($data as $key => $value) {
    foreach ($value['emails'] as $lead) {
        $fname = $lead['first_name'];
        $lname = $lead['last_name'];
        $email = $lead['value'];

        //put objects in array
        $assocDataArray += [ "First Name" => $fname ];
        $assocDataArray += [ "Last Name" => $lname ];
        $assocDataArray += [ "Email" => $email ];
    }
}

var_dump($assocDataArray);

var_dump只给了我一个数组 [预期 10]

本次作业：-

$assocDataArray += [ "First Name" => $fname ];
$assocDataArray += [ "Last Name" => $lname ];
$assocDataArray += [ "Email" => $email ];

错了，改成下面的样子

$assocDataArray[] = [ "First Name" => $fname ,"Last Name" => $lname ,"Email" => $email ];
