Default PHP: Turn relative links into absolute ones?

Hi,

does anyone know of a function to turn relative links in HTML code (<a href="..."></a>, <img src="...">, ...) into absolute links?

Any help is appreciated.

Try this function:

PHP Code:
function absolute_url($txt$base_url){
  
$needles = array('href="''src="''background="');
  
$new_txt '';
  if(
substr($base_url,-1) != '/'$base_url .= '/';
  
$new_base_url $base_url;
  
$base_url_parts parse_url($base_url);

  foreach(
$needles as $needle){
    while(
$pos strpos($txt$needle)){
      
$pos += strlen($needle);
      if(
substr($txt,$pos,7) != 'http://' && substr($txt,$pos,8) != 'https://' && substr($txt,$pos,6) != 'ftp://' && substr($txt,$pos,9) != 'mailto://'){
        if(
substr($txt,$pos,1) == '/'$new_base_url $base_url_parts['scheme'].'://'.$base_url_parts['host'];
        
$new_txt .= substr($txt,0,$pos).$new_base_url;
      } else {
        
$new_txt .= substr($txt,0,$pos);
      }
      
$txt substr($txt,$pos);
    }
    
$txt $new_txt.$txt;
    
$new_txt '';
  }
  return 
$txt;

$txt is your HTML code where you want to convert your relative links. Works like a charm for me!

Hey, that's a nice one. Does exactly what I need.

Thanks, tagammeer (btw, what is "tagammeer"? Is that a name, or does it mean something? Just curious... )

No, it's not a name, "Tag am Meer" is German for "a day at the beach". I hope it gets warmer soon...

Code:
$new_txt = absolute_url($txt, $base_url);
where $txt holds the text that you want to modify and $base_url is the URL of the site.
