From: slevy1 at pipeline dot com Operating system: n/a PHP version: 7.0.0RC3 Package: *General Issues Bug Type: Bug Bug description:ord() no longer yields correct results consistently Description: ------------ I used ord() in combination with mb_strcut() to obtain the byte values of a multibyte char utf-8 encoded. This used to work in PHP 5.4.8 - 5.5.29. But in PHP5.6-PHP7.00rc3 it doesn't work any more :( Test script: --------------- <?php $str = "♥"; // 3 byte values per above var_dump( ord(mb_strcut($str, 0, 1) )); var_dump( ord(mb_strcut($str, 1, 1) )); var_dump( ord(mb_strcut($str, 2, 1) )); see live code: https://3v4l.org/OoFus Expected result: ---------------- I expected the var dumps to produce decimal results as follows: 226 153 165 Actual result: -------------- 0 0 0 -- Edit bug report at https://bugs.php.net/bug.php?id=70591&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70591&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70591&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70591&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70591&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70591&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70591&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70591&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70591&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70591&r=support Expected behavior: https://bugs.php.net/fix.php?id=70591&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70591&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70591&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70591&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70591&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70591&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70591&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70591&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70591&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70591&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70591&r=mysqlcfg
