Input field name syntax

Question

I have got code from a website as:

<input type="text" class="username" name="f[username]" />

While when I want to get form value in php as

echo $_POST["f[username]"];

It shows nothing

check print_r($_POST); and you will come to know how to get value — Death-is-the-real-truth

PHP special cases [] characters in field names in data which populates $_POST and $_GET. It uses them to generate arrays.

$_POST['f']['username']

Well another answer from planet, don't make yourself hard to solve something, just change the name with familiar

<input type="text" class="username" name="username" />

then echo it in your php

echo $_POST['username'];
