Simple BBCode To HTML Function In PHP

January 22, 2007

While working on a “secret” project I needed a simple BBCode to HTML converter. I’m sure there are a number of them out there, but I wanted to build my own. Here it is, a quick and dirty regex filled function.

function bbc2html($content) {
  $content = preg_replace('/(\[b\])(.*?)(\[\/b\])/','$2',$content);
  $content = preg_replace('/(\[i\])(.*?)(\[\/i\])/','$2',$content);
  $content = preg_replace('/(\[u\])(.*?)(\[\/u\])/','$2',$content);
  $content = preg_replace('/(\[ul\])(.*?)(\[\/ul\])/','
    $2
',$content); $content = preg_replace('/(\[li\])(.*?)(\[\/li\])/','
  • $2
  • ',$content); $content = preg_replace('/(\[url=)(.*?)(\])(.*?)(\[\/url\])/','$4',$content); $content = preg_replace('/(\[url\])(.*?)(\[\/url\])/','$2',$content); return $content; }

    In other news this is post #99 since I started the blog. Here’s to hoping #100 is stellar.

    Update (01/23/07)
    I just realized that PHP lets you use arrays in preg_replace, so a ‘better’ version would be…

    function bbc2html($content) {
      $search = array (
        '/(\[b\])(.*?)(\[\/b\])/',
        '/(\[i\])(.*?)(\[\/i\])/',
        '/(\[u\])(.*?)(\[\/u\])/',
        '/(\[ul\])(.*?)(\[\/ul\])/',
        '/(\[li\])(.*?)(\[\/li\])/',
        '/(\[url=)(.*?)(\])(.*?)(\[\/url\])/',
        '/(\[url\])(.*?)(\[\/url\])/'
      );
    
      $replace = array (
        '$2',
        '$2',
        '$2',
        '
      $2
    ', '
  • $2
  • ', '$4', '$2' ); return preg_replace($search, $replace, $content); }
