Re: Re: Fwd: Re: #25494 [Com]: array_merge allowing "false" as argument (silent when non-array is passed)

In my opinion the change is fine, given the current state of affairs a transitional release between 4.3 & 5.0 does not seem likely. Therefor it would only seem logical to give people a fair warning (E_NOTICE) that the (wrong) behavior they are relying upon is not going work/last forever. Otherwise, without a word of warning working code will suddenly become broken code once they upgrade. Most people have their error reporting set to E_ALL ^ E_NOTICE (do not display notices) so it won't affect them anyway. Even then, the behavior itself implies a failure in some code, since an non-array value is passed to a function expecting an array. I venture it would help a number of people find errors in their code that before were nigh impossible to find and/or track down. And yes PHP is typeless, but all of the code using new argument parsing functions will most definitely reject strings passed to functions expecting arrays and vice versa. I see this situations as not being any different. Ilia
