Deprecated help for a newbie

[bjenn85]

function format_bbcode( $text )
  {
  $search  = array( '#\[url=(http|https|ftp)://(.+?)\](.+?)\[/url\]#ie', '#\[url\](http|https|ftp)://(.+?)\[/url\]#ie' );
  $replace = array( 'trunc_url(\'\\1://\\2\',\'\\3\')', 'trunc_url(\'\\1://\\2\',\'\\1://\\2\')' );
  return preg_replace( $search, $replace, $text );
  }
function make_urls( $text )
  {
  $search  = array( '#(^|\s)(http|https|ftp)(://[^\s\[]+)#i' );
  $replace = array( '\\1[url]\\2\\3[/url]' );
  return preg_replace( $search, $replace, $text );
  }

old tiny forum I use and since the latest PHP upgrade I've been building up a huge error_log for deprecated preg_replace

 

can someone please show me how to use preg_replace_callback on these two?

Try changing the format_bbcode function to be

function format_bbcode( $text )
{
    $search  = array( 
        '#\[url=(http|https|ftp)://(.+?)\](.+?)\[/url\]#i', 
        '#\[url\](http|https|ftp)://(.+?)\[/url\]#i'
    );
    
    $text = preg_replace_callback($search, function($m) {
                                                $url = $m[1] . '://' . $m[2];
                                                $link_text = isset($m[3]) ? $m[3] : $url;
                                                return trunc_url($url, $link_text);
                                           }
                                        , $text);

    return $text;
}
