Bug #79262 [NEW]: Calling key() on ArrayObject returns nothing

From: alexander at sulu dot io Operating system: MACOS Mojave PHP version: 7.4.2 Package: Arrays related Bug Type: Bug Bug description:Calling key() on ArrayObject returns nothing Description: ------------ I updated a library which did use \ArrayObject and access its key with the key function. I tested the script with both 7.4.0 and current 7.4.2 the result of the key() call on \ArrayObject does return in 7.4 always null instead on 7.3 it returns successfully the key. For me it looks like all array functions has no effect on the \ArrayObject. Test script: --------------- // should return string(4) "test" will return instead NULL var_dump( key( new \ArrayObject(["test" => "123"]) ) ); -- Edit bug report at https://bugs.php.net/bug.php?id=79262&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79262&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79262&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79262&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79262&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79262&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79262&r=support Expected behavior: https://bugs.php.net/fix.php?id=79262&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79262&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79262&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79262&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79262&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79262&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79262&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79262&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79262&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79262&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79262&r=mysqlcfg
