A small tip in PHP

[litewarez]

Thought i would share a small tip with you about php that not many people know.

Create a file called config.php

and in that file place the following.

return array(
    'db' => array(
        'host' => 'litewarez.com',
        'user' => 'usr'
        //ETC
    ),
);

Then when you need your config just go

$config = include 'config.php';
echo $config['db']['host']; // litewarez.com

I bet you never knew that

I used it before. Here's one pratical example from php.net I based something on a while back.

<?php
//EXAMPLE  of Multi-Dimentional Array where as an array's keys are an array itself.
//It's so easy to create one like this.

$movie_to_watch = array ('Action'=>
          array('Kanu Reeves' => 'Matrix Reloaded',
                      'Pearce Brosnan' => 'Die Another Day',
                      'Tom Cruz' => 'Mission Impossible',
                      'Jason Statham' => 'Crank',
                      'Danzel Washington' => 'Man on Fire'),
                'Comedy' =>
                array ('Charlie Chaplin' => 'City Lights',
                       'Jim Carrey'    => 'Cable Guy',
                       'Rowan Atkinson' => 'The Ultimate Disaster'));
$type_wanted = 'Action'; //You may switch type from Action to Comedy.
$hero_wanted = 'Pearce Brosnan'; // You may switch hero from Pearce Brosnan to Jim Carrey.

print ("$hero_wanted 's  $type_wanted movie is " . $movie_to_watch[$type_wanted][$hero_wanted].".");
// produces browser output as under:
// Pearce Brosnan 's Action movie is Die Another Day.
?>

As you can see instead of having just the 'db' like Litewarez has you can expand it and have more like 'Action' 'Comedy' and 'Drama' etc. Really useful.

Nice tip mate I didn't know this and it is certainly going to be helpful.

Thanks for this. I knew about it too but still needed a good example of implementation.

Thanks, but does this example explains multi dimensional array?

I was guessing what litewarez was doing was having these arrays written in a "return" form and could be retrieved with a variable.

Wow php is full of surprises :P

 

[litewarez]

Yea the tip is creating a php file that returns an array you can then use $variable = include 'some file.php';

And yea this is a multidimensional array lol

Returning inclusions can be useful sometimes but in the case of a config file I am unsure.

I'd definately consider it for some kind of array which, for some reason, I want to constantly name differently.
