Bug #73991 [Asn]: JSON_OBJECT_AS_ARRAY flag does not function.

Edit report at https://bugs.php.net/bug.php?id=73991&edit=1 ID: 73991 Updated by: pollita@php.net Reported by: kruithne at gmail dot com Summary: JSON_OBJECT_AS_ARRAY flag does not function. Status: Assigned Type: Bug Package: JSON related Operating System: All PHP Version: 7.1.1 Assigned To: pollita Block user comment: N Private report: N New Comment: Best as I can recall, the thinking was that internally, options would replace the usage of the separate (zend_bool assoc) flag. Externally.... I'm not sure why we actually exposed the constant :/ As a BC-safe compromise, I'll parse the bool $assoc param as nullable, json_decode($json, null, $options) will then respect the use of JSON_OBJECT_AS_ARRAY in $options. An explicit true/false however will still override the $options integer. Previous Comments: ------------------------------------------------------------------------ [2017-01-25 14:39:12] kruithne at gmail dot com While a very minor thing, I feel it would make more sense to have the associative behavior activated based on EITHER the $assoc (second parameter) or the $options flag (JSON_OBJECT_AS_ARRAY) being true, rather than having the $assoc take undocumented precedence over the activation. ------------------------------------------------------------------------ [2017-01-25 12:20:26] requinix@php.net $assoc always overrides the OBJECT_AS_ARRAY flag, so in that fourth test PHP deliberately unsets it because you passed $assoc=false. I don't know the reasoning behind that (which came from @pollita back in 2010 and PHP 5.4.0) but while removing the unsetting behavior makes sense to me, I'd be wary of changing anything now. ------------------------------------------------------------------------ [2017-01-25 11:38:55] kruithne at gmail dot com Description: ------------ The documentation states that the fourth parameter for json_decode() is a bit-mask value, it goes on to list two possible flags: JSON_OBJECT_AS_ARRAY and JSON_BIGINT_AS_STRING. Despite being redundant (superseded by the second parameter), the JSON_OBJECT_AS_ARRAY flag has no effect on the decoded result when supplied. Test script: --------------- <?php $json = '{"test": "From there to here, and here to there, funny things are everywhere.", "number": 12345678901234567890}'; // Prove json_decode is working by default. // Expected: object(stdClass) (2) {["test"] => string(67) ["number"] => float()} // Result: object(stdClass) (2) {["test"] => string(67) ["number"] => float()} $decoded = json_decode($json); var_dump($decoded); // Prove that passing bit-mask options works. // Expected: object(stdClass) (2) {["test"] => string(67) ["number"] => string(20)} // Result: object(stdClass) (2) {["test"] => string(67) ["number"] => string(20)} $decoded = json_decode($json, false, 512, JSON_BIGINT_AS_STRING); var_dump($decoded); // Prove that the second parameter works for associative conversion. // Expected: array(2) {["test"] => string(67) ["number"] => string(20)} // Result: array(2) {["test"] => string(67) ["number"] => string(20)} $decoded = json_decode($json, true, 512, JSON_BIGINT_AS_STRING); var_dump($decoded); // Attempt to use JSON_OBJECT_AS_ARRAY for associative conversion fails. // Expected: array(2) {["test"] => string(67) ["number"] => string(20)} // Result: object(stdClass) (2) {["test"] => string(67) ["number"] => string(20)} $decoded = json_decode($json, false, 512, JSON_OBJECT_AS_ARRAY); var_dump($decoded); Expected result: ---------------- object(stdClass) (2) {["test"] => string(67) ["number"] => float()} object(stdClass) (2) {["test"] => string(67) ["number"] => string(20)} array(2) {["test"] => string(67) ["number"] => string(20)} array(2) {["test"] => string(67) ["number"] => string(20)} Actual result: -------------- object(stdClass) (2) {["test"] => string(67) ["number"] => float()} object(stdClass) (2) {["test"] => string(67) ["number"] => string(20)} array(2) {["test"] => string(67) ["number"] => string(20)} object(stdClass) (2) {["test"] => string(67) ["number"] => string(20)} ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73991&edit=1
