PHP change link address in html source code

Question

In source code I have address's like this /images/image.jpg js/file.js how to add to this address's server address that will be http://server.com/folder/file.jpg with str_replace() it will be hard, because each folder name is different.

Answer 1

Here is a solution using preg:

$content = '
  <script type="text/javascript" src="/js/script.js"></script>
  blah blah <a href="/images/image1.jpg">image1</a>
  blah blah <a href="/images/image2.jpg">image2</a>
  blah blah <a href="/folder/link1.htm">link1
';

$search = array('#"(/)images/#mi', '#"(/)folder/#mi', '#\"(/)js/#mi');
$replace = "http://site.com$1";

$content = preg_replace($search, $replace, $content);

Answer 2

declare a global variable for your server address, store all your folder names into an array, and traverse it with a loop, and then concatenate the strings. Example: see it in action here

  $server_addr = "http://server.com";   
  //considering $replace and $folder_names have 1:1 correspondence of search and replace values 
 $orig = array("/images/image.jpg", "js/file.js"); //and so on...
 $replace = array("images", "js"); //and so on...
 $folder_names = array('folder'); //and so on...

 for( $i=0; $i<=count($replace); $i++) {
  foreach ($orig as $o)
   $new_path[] = $server_addr . str_replace($replace[$i], $folder_names[$i], $o);
}
