关于curl的一个让我很纠结的问题，求解答
我用curl模拟访问百度的推广，我的目的是通过cookie来获取里面的json数据，现在情况如下：
1、通过模拟登陆到百度推广的网站
2、然后再通过cookie和post参数获取json数据
3、对拿到的json数据进行解析入库
现在问题就是：我在入库到一半的时候，代码显示无法拿到json数据了。然后我将脚本重新执行一次，结果是前面那一半的数据也拿不到了（虽然我已经将这一半数据入库了，但我重新获取，按道理来说是有json数据返回的）。
现在我的理解是，可能是在取json数据时，curl的访问出问题了（但这应该不是代码问题，因为前面已经获取到了一半的数据了，这种情况就像你上网突然断网了一样）
请问各位大侠使用curl时有没有出现过这种情况，求解答！
------解决方案--------------------
全拿到数据判断数据完整性再写入操作。。
------解决方案--------------------
不会出现这种情况吧，只有发送的请求完全返回curl才会获取，post一次，会得到一次响应，要不就是完整的要不就是什么都没有。这个不像显示网页，有时候只有一部分载入进来了，一部分不会显示。

对, 你请求发得太快,对方临时block你了,
请求之间sleep个几秒.....

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
