Use an array within itself in php

Question

is it possible to use array for internal like this?

$b = array(
  'a' => 'Adam',
  'b' => $b['a'].' and eve'
);

If you turned on any amount of error messaging you would get NOTICE Undefined variable: b on line number 5 pretty simple — nerdlyist

No this is not possible, what you can do is this:

$b = array(
    'a' => 'Adam'
);

$b['b'] = $b['a'] . ' and eve';

No that is not possible because the array $b hasn't been created yet when you try to add

'b' => $b['a'];

Instead you should create the array $b, then add the other element. Like so:

$b = array('a' => 'Adam');
$b['b'] = $b['a'] . ' and eve';

No not possible, as doing so would produce E_NOTICE : type 8 -- Undefined variable: b -- at line X _where X is the where you are 'b' => $b['a'] assigning a value to b

No, It's not possible, It will give Error like "Undefined variable: b". If you want to perform anyway, use this one

$b = array('a' => 'Adam'); $b['b'] = $b['a'];
