Edit report at https://bugs.php.net/bug.php?id=75700&edit=1 ID: 75700 Updated by: nikic@php.net Reported by: admin at twister-vl dot ru Summary: Incorrect number after json_encode -Status: Open +Status: Not a bug Type: Bug Package: JSON related Operating System: All PHP Version: 7.2.0 Block user comment: N Private report: N New Comment: The actual result is correct, please see https://3v4l.org/BfqFu. If you'd like to receive the old result (though you should ask yourself why you want that) you can either a) change the serialize_precision setting, understanding that you will no longer receive an accurate floating-point representation, or b) explicitly round your floating point numbers to a lower level of precision.
