Clear all comments but leave PHPDoc

I'm creating a debugging/doc script and I want to ignore all the standard comments but leave the PHPDoc in tact.

The code I was using was:

    // Get file into an array line by line
    $line = file($file);

    // Trim all empty space and # or // comments
    array_map(function($v) {
        $v = trim($v);
        $v = preg_split("/\/\/|#/", $v)[0];
        return $v;
    }, $line);

The problem being, this would still leave the multi-line C-style comments like:

/*
This
means
nothing
*/

So I believe I'll have to read in the entire file, find every /* while ignoring /** (PHPDoc) and removing everything until */.

So the regex would need to be multi-line. I'm open to solutions using file() but I think file_get_content() would be more practical with the finding of C-style open and close comment tags on separate lines.

I reckon the best way about it is to use token_get_all().
