如何忽略 PHP foreach 循环中的提交输入

Question

I want to create a PHP foreach loop that automatically loops through and retrieves submitted any form data. The problem is:

foreach($_POST as $key => $value) { if(!empty($value)) echo $key. “ - “. $value.”<br>”;

will also print out the final

<input type=“submit” name=“foo” value=“bar”>

input, which I want to ignore.

This works if I change from input to button tag, however I prefer to keep input tag. Ta.

For get all Get And Post Fields From Request

public function getAll()
{
   $request = $_SERVER['REQUEST_METHOD'];
   $data = [];
        if ($request === 'GET') {
            foreach ($_GET as $key => $value) {
                $data[$key] = filter_input(INPUT_GET, $key, FILTER_SANITIZE_SPECIAL_CHARS);
            }
        }
        if ($request === 'POST') {
            foreach ($_POST as $key => $value) {
                $data[$key] = filter_input(INPUT_POST, $key, FILTER_SANITIZE_SPECIAL_CHARS);
            }
        }
        return $data;
}

For take only non empty fileds..do..inside foreach loop

if(!empty($value))
{
  $data[$key] = filter_input(INPUT_POST, $key, FILTER_SANITIZE_SPECIAL_CHARS);  
}
