Accessing data from external websites to 'create' own application of that data - php

Question

Wow, i hope i have written the title in a correct way, because i really have no idea how this is called.
Let me explain what i am looking for.
I have a simple application. And it contains the following:
- Frontpage (salespage)
- Admin area
- Member area
- Database to provide the app of data
I have hosted the basics of this application on a server, let's call it 'www.the.app'. And i have written it in PHP using Laravel.
Now i want to use the functions of the app, which is hosted on www.the.app and use the functions like the admin area, member area, the frontpage and create my own database on 'www.awesome.app'.
What would be the best way to make such a thing happen?
I am not looking for direct solutions. I am just looking for information to point me in the right direction to be able to make the above reality. Anything would be apreciated, like information, a name i can search on, what ever is related to this.
And if there is any more information needed, let me know please :)

Here is exactly how you can do it :
1) To Auto Login To The Site :
Note : As you will need to probably get data from login based site so you can auto login to the site through using CURL while using User Credentials with it.

2) Extracting Data After Logging In Through CURL :
Note : After logging to the site now you will need to use PHP DOM to extract data from the site.So you can extract data something like this way by using PHP Simple HTML DOM Parser Library.

//URL To Download Images From
$url = "http://www.facebook.com/"
// Create DOM from URL or file
$html = file_get_html($url);
// Find all images
$i=1;
foreach($html->find('img') as $element) {
$url = $element->src;
$img = "/my_folder/image_".$i.".png";
file_put_contents($img, file_get_contents($url));
$i++;
}
