PHP regular expression problem? ?

<code class="php">$pattern = "/(abcd){1,2}.*(efgh){1,2}/";
$string = "abcd123efgh456";
preg_match_all($pattern,$string,$result);</code>

---

I will write it like this. Put abcd and efgh into the result array. I hope to put abcd into the array instead of putting efgh into the array. How to write this pattern?

Thank you
