#48214 [NEW]: mb_substr or mb_convert_encoding not working

From: b at ssel dot me Operating system: CENTOS 4.7 i686 PHP version: 5.2.9 PHP Bug Type: *Unicode Issues Bug description: mb_substr or mb_convert_encoding not working Description: ------------ for some reason when using mb_substr or mb_convert_encoding php page dies without any error even when error reporting is set to error_reporting(E_ALL); that will happen only if we changed php.ini settings to: upload_max_filesize: 10M post_max_size: 10M max_execution_time:120 max_input_time: -1 I don't think those settings are related to mb_substr, but that what was happening on php 5.2.5 and still happening on 5.2.9 Reproduce code: --------------- $intsub = mb_substr($intwalker[0], 0, 200); if ($intsub != $intwalker[0]){ $intsub = $intsub." ......"; } } $intsub = mb_convert_encoding($intsub, "utf8", "auto"); Expected result: ---------------- to see a text of the only 200 first chars of $intwalker[0] Actual result: -------------- nothing, just a white page no errors at all even if error_reporting(E_ALL); -- Edit bug report at http://bugs.php.net/?id=48214&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48214&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48214&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48214&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48214&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48214&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48214&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48214&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48214&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48214&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48214&r=support Expected behavior: http://bugs.php.net/fix.php?id=48214&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48214&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48214&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48214&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48214&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48214&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48214&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48214&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48214&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48214&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48214&r=mysqlcfg
