Description: ------------ The chr function translate a single Byte length integer into it's ASCII value. When providing a number bigger then 255, it returns the first byte instead of reporting an error about being out of range. Test script: --------------- echo chr(1000) . ' ' . ord(chr(1000)) . "\n"; Expected result: ---------------- chr must check the numeric boundaries and report on on an error when they are out of the range. Actual result: -------------- returns the first byte out of the result, making it appear like an integer overflow that the carry flag exception was captured. -- Edit bug report at https://bugs.php.net/bug.php?id=63510&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63510&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63510&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63510&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63510&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63510&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63510&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63510&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63510&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63510&r=support Expected behavior: https://bugs.php.net/fix.php?id=63510&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63510&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63510&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63510&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63510&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63510&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63510&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63510&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63510&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63510&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63510&r=mysqlcfg
