Previous Comments: ------------------------------------------------------------------------ [2016-01-08 00:49:20] hungry dot rahly at gmail dot com Then a removal of the warning would be best, because with the warning, you are saying there is a problem, when in fact, there isn't. ------------------------------------------------------------------------ [2016-01-08 00:43:06] bwoebi@php.net This indeed is expected behavior; the only possible thing eventually subject to change in future is whether the warning will be removed. But a DivisionByZeroError is definitely not suitable here as divisions by zero are handled like floating point divisions. (Yielding ±INF or NaN) Just for integer divisions (intdiv) and modulo, there's no valid result, hence an exception is then thrown (instead of false like before). ------------------------------------------------------------------------ [2016-01-07 23:27:19] hungry dot rahly at gmail dot com Description: ------------ It doesn't seem to throw an exception for an ACTUAL division of 0 ($var1 / $var2) and still presents as a warning Test script: --------------- <?php echo PHP_VERSION."\n"; $x = 5; $y = 0; try { print "here1\n"; $z = $x % $y; print "here2 - $z\n"; } catch(Error $e) { print "here ERROR 1 ".get_class($e)."\n"; } try { print "here3\n"; $z = $x / $y; print "here4 - $z\n"; } catch(Error $e) { print "here ERROR 2 ".get_class($e)."\n"; } try { print "here5\n"; $x = intdiv((int)$x, $y); print "here6 - $z\n"; } catch(Error $e) { print "here ERROR 3 ".get_class($e).
