it is possible to perform something like this but a working solution:

if(preg_match("/<span style=\"\">(*.)</span>/i",$original))
{
      $original = str_replace('<span style="">(*.)</span>','',$original);
}

also i want to remove any </span> tags that "dont" have a opening <span>

Not possible until you write a simple parser which can detect closing spans/tags. But what next. Which is the wrong closing tag that should be removed? As the spans can be nested the whole thing must use a stack which is not possible with regular expressions.

To replace the content of all spans which have an empty style use:
$original = preg_replace('/\<span style=""\>(*.?)\<\/span\>/i',$original)

^ same question.

If you're trying to remove all with a style attr:

$original = preg_replace('#<span style=".*?">.*?</span>#si', '', $original);

To remove ALL <span></span> tags:

$original = preg_replace('#<span[^>]*?>.*?</span>#si', '', $original);

>>you are you trying to match ?? are you trying to remove all <span that have a style attr. ?

say i have this string:

$original = 'Some <span style="">value</span> that is wrapped with empty span tags';

well i want to remove the empty <span style=""></span> but keep the value in-between.
