This is all a bit moot anyway, the RFC proposal is for warnings or notices on implicit casts only.
I'm not a voting member for RFCs so my opinion is mere food for thought, nonetheless my two cents is that: a) The proposal relies on a premise that an implicit cast of (non-zero fractional) float to int is inherently ambiguous or a mistake. I disagree with this as outlined in my previous messages; namely my objection is truncating a float on cast to int is the widely established normal behaviour in numerous programming languages. There should not be a penalty in the form of an error just for doing such a conversion implicitly, in accordance with how PHP's type coercion works by design. b) String offsets, where a warning occurs already, is something of a special case; this warning was added I believe (5.4?) because malformed string offset was a known common error in the community. It's not even entirely consistent; $foo["2"] is fine, $foo[2.5] is a warning with offset [2], $foo["2x"] is a warning with offset [2] and $foo["2.5"] is a TypeError. c) It's a substantial BC breaking change likely to affect a lot of existing code, even though that code works as intended. d) If it is implemented at all, it should not be an error level as high as a warning. -Dave On Sat, Feb 6, 2021 at 7:32 PM Rowan Tommins <rowan.coll...@gmail.com> wrote: > On 06/02/2021 14:47, Christian Schneider wrote: > > I'm sure there is a lot of code which takes user input and uses (int) > casts to ensure they are dealing with integers. > > There is also intval() as an alternative but my guess would be that real > world code uses 50% (int) and 50% intval() to do this. > > > My thoughts exactly.
