 My practice is that I initialize only arrays and boolean variables,
 I rarely set a string to '' (if not really required) and I 
 suggest to use the same practice here (as PHP has weak typing anyway
 and this only clutters up code IMHO).

 Another change in connection with this is to return 'true' or 'false' 
 explicitly where a boolean return value is expected
 (see my mail about the matchcondition patch yesterday).
