Bug #73503 [NEW]: Missing entry in the migration guide

From: alec Operating system: PHP version: 7.1.0RC6 Package: Documentation problem Bug Type: Bug Bug description:Missing entry in the migration guide Description: ------------ I just hit the "regression" described in #53432 and I didn't find anything about this in the migration guide for PHP 7.1. I found only http://php.net/manual/en/migration71.incompatible.php#migration71.incompatible.empty-string-index-operator which is not the same. I think it should be stated in the migration guide that any use of [] operator on an empty string results in a warning ("Illegal string offset") and the operation does not work, leaving the variable to be an empty string still. -- Edit bug report at https://bugs.php.net/bug.php?id=73503&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73503&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73503&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73503&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73503&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73503&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73503&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73503&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73503&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73503&r=support Expected behavior: https://bugs.php.net/fix.php?id=73503&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73503&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73503&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73503&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73503&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73503&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73503&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73503&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73503&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73503&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73503&r=mysqlcfg
