I plead that it's his statement that is not technically correct. 1. php does a soft comparison ('==' rather than '===') so the results of each case expression is auto-cast to a boolean (in the case of switch'ing on TRUE), ergo there is no 'as long', statements will always resolve to a boolean ... only they may not do it in a way that is readily understood by everyone. 2. the php engine specifically allows for 'complex expression' cases testing against a boolean switch value ... not best practice according to some but very much technically correct according to the php implementation. > Cheers, > > tedd >
