特定网页的PHP子页面提取器

Question

Is it possible by PHP code to extract all subpages links for particular website For example We have completely independent and not linked pages in on web address

examplepage.com (contains just Hello World)
examplepage.com/1.php (contains some data)
examplepage.com/2.php (contains some data)
examplepage.com/3.php (contains some data)
...
examplepage.com/999999.php (contains some data)
examplepage.com/subfolder/1.php (contains some data)
examplepage.com/subfolder/2.php (contains some data)
examplepage.com/subfolder/3.php (contains some data)
...
examplepage.com/subfolder/999999.php (contains some data)
examplepage.com/subfolder/subfolder2/1.php (contains some data)
examplepage.com/subfolder/subfolder2/2.php (contains some data)
etc.

And I want my php code to scan examplepage.com for all subpages related with that domain and to give me report about all links of all pages (subpages of the main domain) in particular domain

examplepage.com (contains just Hello World)
    examplepage.com/1.php (contains some data)
    examplepage.com/2.php (contains some data)
    examplepage.com/3.php (contains some data)
    ...
    examplepage.com/999999.php (contains some data)
    examplepage.com/subfolder/1.php (contains some data)
    examplepage.com/subfolder/2.php (contains some data)
    examplepage.com/subfolder/3.php (contains some data)
    ...
    examplepage.com/subfolder/999999.php (contains some data)
    examplepage.com/subfolder/subfolder2/1.php (contains some data)
    examplepage.com/subfolder/subfolder2/2.php (contains some data)
    etc.

Is it possible such php code or not?
