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 this bug report at https://bugs.php.net/bug.php?id=79262&edit=1
