<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>General: Remove a few `is_object()` checks followed by `instanceof` operator.
This is a minor performance enhancement:
* If an object is passed, the call to `is_object()` will be redundant.
* If a non-object is passed, the `instanceof` operator (a variant of `is_a()`) will first [https://github.com/php/php-src/blob/f42992f/Zend/zend_builtin_functions.c#L630-L631 check if it is an object] before doing any further processing.
Therefore, no additional processing cycles should be wasted in both cases.
