Req #81417 [NEW]: Add a configuration option to determine if reading an undefined array key shoul

From: nicolas at gestixi dot com Operating system: PHP version: 8.0.10 Package: *Configuration Issues Bug Type: Feature/Change Request Bug description:Add a configuration option to determine if reading an undefined array key shoul Description: ------------ In some languages, such as JavaScript, accessing an undefined array key can be performed silently without throwing an error. We have a 10 years old code base which does conditions like this everywhere: if ($array['key']). With PHP 8, this coding style throws a warning if the key is not defined. Replacing it by `if (array_key_exists('key', $array) && $array['key'])` would take us weeks... and, I actually prefer our actual syntax which I found more readable. For these reasons, I do not plan to upgrade all our code base to avoid this warning. And I do not want to ignore all warnings just for this one... Would it be possible to add a configuration setting to determine if this coding style should throw a warning, a notice or be silently ignored? Another solution I see would be to be able to ignore specific warnings/notices. -- Edit bug report at https://bugs.php.net/bug.php?id=81417&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81417&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81417&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81417&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81417&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81417&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81417&r=support Expected behavior: https://bugs.php.net/fix.php?id=81417&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81417&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81417&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81417&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81417&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81417&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81417&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81417&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81417&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81417&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81417&r=mysqlcfg
