From: juzna dot cz at gmail dot com Operating system: Ubuntu 10.04 PHP version: 5.4.6 Package: JSON related Bug Type: Bug Bug description:errors json_encode do NOT call error handler
Description: ------------ When there is an error within json_encode (e.g. due to invalid utf8), E_WARNING should be raised. However, that doesn't happen in some cases. It doesn't happen when display_errors is set to On. In latest snapshot of 5.4 it does not happen at all. Test script: --------------- <?php /** * WTF? Error handler is not called, when display_errors=On * * _errorHandler must be called in each case, but it's not. * * Results differ on different PHP versions. */ function _errorHandler($severity, $message, $file, $line, $context) { $GLOBALS['err'] = func_get_args(); // echo "Error ($severity) $message in $file:$line\n"; } set_error_handler('_errorHandler'); // display_errors = Off, works fine { ini_set('display_errors', 0); // Calls error handler, fine $err = NULL; $tmp = substr(new stdClass(), 1, 1); var_dump($err[0], $err[1]); // Calls error handler, fine $err = NULL; $tmp = json_encode(array("bad utf\xFF")); var_dump($err[0], $err[1]); } // display_errors = On, WTF??? { ini_set('display_errors', 1); // Calls error handler, fine $err = NULL; $tmp = substr(new stdClass(), 1, 1); var_dump($err[0], $err[1]); // Does NOT call error handler, WTF??? $err = NULL; $tmp = json_encode(array("bad utf\xFF")); var_dump($err[0], $err[1]); } Expected result: ---------------- int(2) string(55) "substr() expects parameter 1 to be string, object given" int(2) string(49) "json_encode(): Invalid UTF-8 sequence in argument" int(2) string(55) "substr() expects parameter 1 to be string, object given" int(2) string(49) "json_encode(): Invalid UTF-8 sequence in argument" Actual result: -------------- On 5.4.6: int(2) string(55) "substr() expects parameter 1 to be string, object given" int(2) string(49) "json_encode(): Invalid UTF-8 sequence in argument" int(2) string(55) "substr() expects parameter 1 to be string, object given" NULL NULL On 5.4-latest: int(2) string(55) "substr() expects parameter 1 to be string, object given" NULL NULL int(2) string(55) "substr() expects parameter 1 to be string, object given" NULL NULL -- Edit bug report at https://bugs.php.net/bug.php?id=63004&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63004&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63004&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63004&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63004&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=63004&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=63004&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63004&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63004&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63004&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63004&r=support Expected behavior: https://bugs.php.net/fix.php?id=63004&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63004&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63004&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63004&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63004&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63004&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63004&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63004&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63004&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63004&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63004&r=mysqlcfg
