You will find the name in the $_POST array.
您将在 $_POST 数组中找到该名称。
<?php
print_r($_POST);
?>
This way you will see everything in the $_POST array.
这样您将看到 $_POST 数组中的所有内容。
You can iterate through the array with:
您可以使用以下命令遍历数组：
foreach($_POST as $name => $content) { // Most people refer to $key => $value
echo "The HTML name: $name <br>";
echo "The content of it: $content <br>";
}

'submitbutton'is the name of your submit button.
you can get the names of super global $_POST array elements with array_keys()function
'submitbutton'是提交按钮的名称。您可以使用array_keys()函数获取超级全局 $_POST 数组元素的名称
$postnames = array_keys($_POST);

Its like any other POST variable, the name will be in the $_POST array. The name is the key in the $_POST array.
它与任何其他 POST 变量一样，名称将在 $_POST 数组中。该名称是 $_POST 数组中的键。
