[php-src] Issue #9296: `ksort(..., SORT_REGULAR)` behaves incorrectly on arrays with string and numeric keys since PHP 8.0

Issue: https://github.com/php/php-src/issues/9296 Author: Ramzeeset ### Description The behavior of the string and number comparison operators has been changed since php 8, but ksort and krsort functions still use the old rules. It leads to inconsistent situations, when after ksort the first key is ***greater*** than some of the next ones by according to the basic comparison operators. The following code: ```php <?php $array = ["600" => 0, "aaa" => 1]; ksort($array, SORT_REGULAR); var_dump($array); var_dump(array_key_first($array) <=> array_key_last($array)); ``` Resulted in this output: ``` array(2) { ["aaa"]=> int(1) [600]=> int(0) } int(1) ``` But I expected this output instead: ``` array(2) { [600]=> int(0) ["aaa"]=> int(1) } int(-1) ``` ### PHP Version PHP 8.0 ### Operating System _No response_
