Playing around with regex is a difficult thing for me.

I am trying to get the "values" **149** and **150** out of this string:

```
a:1:{s:7:"sliders";a:1:{s:10:"fullscreen";a:5:{s:6:"slides";a:2:{i:47;a:4:{s:9:"attach_id";s:3:"149";s:10:"slide_type";s:5:"image";s:5:"title";a:2:{s:5:"value";s:0:"";s:5:"color";s:0:"";}s:7:"caption";a:2:{s:5:"value";s:0:"";s:5:"color";s:0:"";}}i:48;a:4:{s:9:"attach_id";s:3:"150";s:10:"slide_type";s:5:"image";s:5:"title";a:2:{s:5:"value";s:0:"";s:5:"color";s:0:"";}s:7:"caption";a:2:{s:5:"value";s:0:"";s:5:"color";s:0:"";}}}s:9:"fit_style";s:7:"default";s:8:"controls";s:7:"default";s:6:"thumbs";s:3:"yes";s:8:"autoplay";s:7:"default";}}}

```

I tried this without any good results:

```
/^.*_id";s:3:"(.*)";.*$/

```
