获取具有数组名称的表单控件的值

Question

I have a named form control:

<input class="form-control" name="user['first_name']" value="">

How can I get its value after it has been submitted via POST?

I tried these and none of them seems to work:

echo $_REQUEST['user']->fname;
echo $_POST['user[fname]'];
echo $_POST['user']['fname'];

Answer 1

Try this, get all value using foreach loop

foreach ($_POST as $key => $value) {
    //do something
    echo $key . ' has the value of ' . $value;
}
