What Is The Right Way Of Usig " And ' Inside Sub-arrays In PHP And HTML?

Which of the following ways is the right one in using the characters ' and ' inside PHP's sub-arrays? #1 Way in debugging PHP code $_POST['login['username']']; #2 My original way

Solution 1:

You don't need to quote the array keys in HTML, this is correct:

<input name="login[password]" type="password" cols="92" />

This will create in $_POST a key 'login' whose value is another array having the key 'password', so you can access it like:

$_POST['login']['password']

Solution 2:

First of all, the correct form in html is what you have for #22 (no quotes).

Secondly, the entire point of doing this is because it will convert it into an array. When this form is posted, an array is created INSIDE of $_POST called login. To access it, try this:

echo $_POST['login']['username']; //echos username
echo $_POST['login']['password']; //echos password

Here's a quick overview of how the nesting looks:

'_POST' =>
    array
      'login' => 
        array
          'username' => string 'myusername' (length=10)
          'password' => string 'mysecretpassword' (length=16)

Try doing this to get a good idea of what's going on and get output like above:

echo "<pre>";
var_dump($_POST);
echo "</pre>";

You'll be able to see all the nesting.

Solution 3:

just give your variables normal names: username, password and email. you're creating your own problem.
