PHP regular expression question

Here’s some sample XHTML.

 <!-- 5-image layout -->
 <div class="loa_line">
  <div class="loa_trailer">{BOX_TRAILER}</div>
  <div class="loa_img1">{BOX1_IMAGE}</div>
 </div>
 <div class="header"></div>
 <div class="loa_line">
  <div class="loa_img2">{BOX2_IMAGE}</div>
  <div class="loa_img2">{BOX3_IMAGE}</div>
  <div class="loa_links">{BOX4_TEXT}</div>
 </div>

Let’s say I want to extract {*} from this and store them as an array. My current preg_split regex is:

"[\{(.*?)\}]"

This however gives me the following output:

Array ( [0] =>
[1] =>
[2] =>
[3] =>
[4] =>
[5] =>
)

It’s counted the number of {} instances correctly (er, I think. It seems to have added one). However, it did not return the {}. The array is populated with empty values.

How would I go about getting the "{*}"s as strings in an array? I want to use them for a later function, see.
