Note Submitter: kermodebear at kermodebear dot org ---- To kieran at kieran dot ca : Your initial code does not work because default value must be a static value. From the manual: "The default value must be a constant expression, not (for example) a variable, a class member or a function call." So, a default value cannot be sest to another variable. There are a lot of work arounds for this, including your method. Setting default parameters to FALSE then using === to compare works well, as does using func_num_args() in some cases. The best solution will, of course, depend on the problem. Hope this helps someone out there!
