Bug #60111 [Fbk->Csd]: JSON_NUMERIC_CHECK option mangles certain values

Edit report at https://bugs.php.net/bug.php?id=60111&edit=1 ID: 60111 User updated by: digit6 at gmail dot com Reported by: digit6 at gmail dot com Summary: JSON_NUMERIC_CHECK option mangles certain values -Status: Feedback +Status: Closed Type: Bug Package: JSON related Operating System: FreeBSD PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: ^^ You are actually right on this. I was not taking into account that JSON_NUMERIC_CHECK's actual purpose is to look for strings of numeric values and automatically convert them to int values. In my example of forcing a string type on the numeric string, would still require NUMERIC_CHECK to reformat the var type. I was simply using JSON_NUMERIC_CHECK to ensure all my number values were integers, the fact that my platform may use a long set of numbers with no alpha chars in a "tracking number" field would break my implementation was not considered. I'm closing the bug, I'll have to just make sure I'm forcing int values where I require it manually. Thanks!

There is definitely a bug here. ------------------------------------------------------------------------ [2011-10-22 00:17:18] digit6 at gmail dot com Incorrect ACTUAL output entered in bug, here is the real actual output: {"test":3.43434343434e+15} ------------------------------------------------------------------------ [2011-10-21 22:56:05] digit6 at gmail dot com Description: ------------ json_encode will produce undesired results when used with JSON_NUMERIC_CHECK when one or more values is longer than 12 digits, ex: 3434343434343434. The resulting JSON encoded string has the above value listed as: 3434343434340000. Removing the JSON_NUMERIC_CHECK option fixes the problem, but then all other numeric values are returned as strings rather than integers. Test script: --------------- $test = array("test"=>3434343434343434); $test = json_encode($test, JSON_NUMERIC_CHECK); echo $test; Expected result: ---------------- {"test":3434343434343434} OR {"test":"3434343434343434"} Actual result: -------------- {"test":3434343434340000} ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60111&edit=1
