Deprecation : passing null to parameter #2 ($flags) of type int is deprecated for ksort

[monnardj]

In php 8.1, the $flags argument for function ksort can no longer be null. In /local/kaltura/API/KalturaClientBase.php, line 442, this function is called with the $flags argument having the value null. This produces the following warning :

Deprecated: ksort(): Passing null to parameter #2 ($flags) of type int is deprecated in .../KalturaClientBase.php on line 442

In future versions of php, this warning might become a fatal error. The code should be modified so that $flags is never null. The $flags parameter could be removed from ksortRecursive, and ksort will use the default value SORT_REGULAR (see https://www.php.net/manual/en/function.ksort.php).
