Answer 1

您将使用$_GET['numeral']捕获URL变量，并使用$_POST['numeral']捕获表单变量（除非您的表单方法是GET 。

Answer 2

for $_REQUEST it depends on your php.ini how do variables get passed, read here , usually it's the $_POST that will pass, for the rest is the same:

$_GET['nameval'] = abc
$_POST['nameval'] = your input form
$_REQUEST['nameval'] = your input form
