Question

I got configuration file database.php

<?php defined('_ENGINE') or die('Access Denied'); return array (
  'adapter' => 'mysqli',
  'params' => 
  array (
    'host' => 'localhost',
    'username' => 'root',
    'password' => 'root',
    'dbname' => 'db',
    'charset' => 'UTF8',
    'adapterNamespace' => 'Zend_Db_Adapter',
  ),
  'isDefaultTableAdapter' => true,
  'tablePrefix' => 'engine4_',
  'tableAdapterClass' => 'Engine_Db_Table',
); ?>

How to get only password from this array?

something like echo $array['password'];

How do I get the array from database.php?

You’ll need to include the file and bind the returned value to a variable, such as in the below example.

$db_conf = require ('/path/to/database.php');

$db_conf will contain the data returned by database.php.

How do I read the specific value from my array?

Since you are working with a nested array the solution is not as far away as you might think. First use $a[key] to get to the array stored under params, and then get the value of password from there.

As in the below example.

$password = $array['params']['password'];

Note: The above is, in a logical sense, equivalent to;

$params   = $array['params'];
$password = $params['password'];

I tried the above but it’s just shouting "Access Denied" in my face, why?

To protect database.php from unintended access it has been protected with a check to see so that it’s being used inside of the engine.

The script will die if _ENGINE is not defined.

If you want to use database.php in a script outside of the thought of engine you’ll need to define the _ENGINE constant before includeing the file.

define ('_ENGINE', 1);

...

$db_conf = include ('database.php');
