答：
private static function handleData($result,$user_id){
foreach ($result as $k1 => $v1) {
if (!empty($v1['coupon_log'])) {
$num = 0;
foreach ($v1['coupon_log'] as $k2 => $v2) {
if ($v2['user'] == $user_id) {
$num = $num + 1;
}
$result[$k1]['receive_number'] = $num; // 新增单元并赋值
}
} else {// 如果数组为空
$result[$k1]['receive_number'] = 0;
}
// 处理其他业务逻辑...
if($v1['limit_number']!==0){
if($v1['receive_number'] >= $v1['limit_number']){
unset($result[$k1]);
}
}
unset($result[$k1]['coupon_log']);// 移除
}
return array_values($result);// array_values() 原始数据是数组，经过unset后，多出了下标，变成了对象,让数组只返回值，不返回键名
}
