Bug #61537 [NEW]: json_encode() incorrectly truncates/discards information

From: joey Operating system: all PHP version: 5.4.0 Package: JSON related Bug Type: Bug Bug description:json_encode() incorrectly truncates/discards information Description: ------------ When json_encode() cannot correctly encode its argument into JSON, the expected behaviour is that it will return false, and people can check json_last_error() to see why it failed. Currently, it will replace all data it could not encode with the string 'null'. This can lead to what appears to be silently discarding data. Test script: --------------- <?php var_dump(json_encode(chr(215)), json_last_error()); Expected result: ---------------- bool(false) int(5) Actual result: -------------- string(4) 'null' int(5) -- Edit bug report at https://bugs.php.net/bug.php?id=61537&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61537&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61537&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61537&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61537&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61537&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61537&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61537&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61537&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61537&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61537&r=support Expected behavior: https://bugs.php.net/fix.php?id=61537&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61537&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61537&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61537&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61537&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61537&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61537&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61537&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61537&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61537&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61537&r=mysqlcfg
