syntax error in class

Hello guys, I encountered a syntax error, and cannot figure out the reason, for example: ============================== CODE ============================== 1:<?php 2:$opts = array ('header'=>'str1'.'str2'); 3:?> =============================== Works fine, but when I try to put it into a class, say: ============================== CODE ============================== 1:<?php 2:class Test 3:{

4:    var $opts = array ('header'=>'str1'.'str2');

5:} 6:?> ============================== OUTPUT ============================== Parse error: syntax error, unexpected '.', expecting ')' in C:\Documents and Settings\Administrator\Local Settings\Temp\VI42E5.tmp on line 4 PHP Parse error: syntax error, unexpected '.', expecting ')' in C:\Documents and Settings\Administrator\Local Settings\Temp\VI42E5.tmp on line 4 ==================================================================== I got the syntax error. Why?
