oci8: deprecation warning in selectLimit() on PHP 8.1

[wesyah234]

This is to prevent a PHP 8.2 warning

Thanks for your contribution.

I assume that by null $inputArr you actually mean that the parameter has not been provided and the variable is therefore set to its default value of false (not null), triggering the Automatic conversion of false to array is deprecated warning at line 892, which does not occur when $inputarr === null.

I'm fine with the proposed change, even though it may be cleaner to change the parameter's default value to [] - but I'd rather not change the function's signature in a hotfix release.

Also, this deprecation was introduced in PHP 8.1, not 8.2.
