Can formData append be passed in? How does PHP get the value added by append?

You can also continue to add new key-value pairs based on the existing form data, as follows:

<code>var formElement = document.getElementById("myFormElement");
formData = new FormData(formElement);
formData.append("number", 123);
oReq.send(formData);

那么php怎么获取到number123</code>
