Bug #75986 [NEW]: JSON parser not following preposed RFC

From: welfordmartin at gmail dot com Operating system: Ubuntu Server 16.04 & Windows 10 PHP version: 7.2.2 Package: JSON related Bug Type: Bug Bug description:JSON parser not following preposed RFC Description: ------------ When using json_decode to decode a string value containing "{" or "}" the validation fails and it does not produce an object this even happens when both are UTF-8 encoded with "\x7B" and "\x7D" respectfully. both cases cause a 'JSON_ERROR_SYNTAX', While the JSON code has been manually checked against the RFC4627 and it says standard C strings well I can't believe I have to point this one out to you but using "{" and "}" are both ASCII chars so valid in a string. The JSON also parses correctly in Web Browsers both Chrome, Edge & IE parsers. JSON Code used: { "defaultModel":"Campaign", "routes" : { "getCampaignsForWebsite":{ "scope" : "read_campaigns", "api":{ "method" : "GET", "uri" : "/campaign/\x7BdisplayType\x7D/\x7Bwebsite_id:\d+\x7D" }, "perms":{ "module" : "website", "requirement" : "read" } }, "getSingleCampaign":{ "scope" : "read_campaigns", "api":{ "method" : "GET", "uri" : "/campaign/\x7Bcampaign_id:\d+\x7D" }, "perms":{ "module" : "campaign", "requirement" : "read" } } } } Test script: --------------- $raw = file_get_contents("test.json"); $json = json_decode($raw, true); switch (json_last_error()) { case JSON_ERROR_NONE: echo ' - No errors'; break; case JSON_ERROR_DEPTH: echo ' - Maximum stack depth exceeded'; break; case JSON_ERROR_STATE_MISMATCH: echo ' - Underflow or the modes mismatch'; break; case JSON_ERROR_CTRL_CHAR: echo ' - Unexpected control character found'; break; case JSON_ERROR_SYNTAX: echo ' - Syntax error, malformed JSON'; break; case JSON_ERROR_UTF8: echo ' - Malformed UTF-8 characters, possibly incorrectly encoded'; break; default: echo ' - Unknown error'; break; } Expected result: ---------------- I expect an array result when using assoc or a stdClass object when not. Actual result: -------------- Null and json_last_error results in JSON_ERROR_SYNTAX -- Edit bug report at https://bugs.php.net/bug.php?id=75986&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75986&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75986&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75986&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75986&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75986&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75986&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75986&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75986&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75986&r=support Expected behavior: https://bugs.php.net/fix.php?id=75986&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75986&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75986&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75986&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75986&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75986&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75986&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75986&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75986&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75986&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75986&r=mysqlcfg
