Description: ------------ json_encode returns false if the string contains ill-formed byte sequences. It is hard to find the problem since a lot of web applications don't expect the existence of ill-formed byte sequences. The one example is Symfony's JsonResponse class. https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundat ion/JsonResponse.php#L83 Introducing json_encode's option for replacing ill-formd byte sequences with substitute characters (such as U+FFFD) save writing the logic. function json_encode2($value, $options, $depth) { if (is_scalar($value)) { return json_encode($value, $options, $depth); } $value2 = []; foreach ($value as $key => $elm) { $value2[str_scrub($key)] = str_scrub($elm); } return json_encode($value2, $options, $depth); } // https://bugs.php.net/bug.php?id=65081 function str_scrub($str, $encoding = 'UTF-8') { return htmlspecialchars_decode(htmlspecialchars($str, ENT_SUBSTITUTE, $encoding)); } The precedent example is htmlspecialchars's ENT_SUBSTITUTE option which was introduced in PHP 5.4. json_encode shares the part of logic used such as php_next_utf8_char by htmlspecialchars since PHP 5.5. https://github.com/php/php-src/blob/master/ext/json/json.c#L369 Another reason for introducing the option is existence of JsonSerializable interface. Accessing jsonSerialize method's values come from private properties is hard or impossbile. The one of names of candiates for the option is JSON_SUBSTITUTE similar to htmlspecialchar's ENT_SUBSTITUTE option. json_encode($object, JSON_SUBSTITUTE); -- Edit bug report at https://bugs.php.net/bug.php?id=65082&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65082&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65082&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65082&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65082&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65082&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65082&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65082&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65082&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65082&r=support Expected behavior: https://bugs.php.net/fix.php?id=65082&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65082&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65082&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65082&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65082&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65082&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65082&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65082&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65082&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65082&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65082&r=mysqlcfg
