I am doing a preg\_replace:

```
$pattern = '/<ul>/';
$replacement = "";
$string = "hello <ul> how are you doing </ul>";
echo preg_replace($pattern, $replacement, $string);

```

That will replace my `<ul>` with `""` but Id like to replace anything that is a `<ul>` or `</ul>`, I am not getting how to use the `|` (or) character though.

I try like this, but it is not working right:

```
$pattern = '/<ul>|</ul>/';
$replacement = "";
$string = "hello <ul> how are you doing </ul>";
echo preg_replace($pattern, $replacement, $string);

```

Any help would be surely appreciated

Thanks,
Bryan
