Question

i have been working on one tool lately. It grabs all the link addresses from the website.

My problem is that links in html code sometimes is different:

• /index.php
• index.php
• http://www.website.com/index.php

I need to make all links same:

/index.php                       -> http://www.website.com/index.php
index.php                        -> http://www.website.com/index.php
http://www.website.com/index.php -> http://www.website.com/index.php

Thanks for help.

Answer 1

Using preg_replace to fix relative urls

Requires:
$domain = the subject sites domain
$path = the document or string you are looking for relative links with in.

Returns:
$url = the doument or string with the links within it converted to proper urls with the domain given.

Code:

$url = preg_replace('<a\shref="([\/\?\w\.=\&]+)"([\s]rel="(\w+)")*>/', '<a href="http://{$site_domain}$1" rel="$3">' $path)  

good luck, let me know how it goes.
