two deprecated warnings in /wp-includes/functions.php

[rpayne7264]

two deprecated warnings in /wp-includes/functions.php:

1) Backtrace from warning strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated at /wp-includes/functions.php 7329:

this is the code causing the error: $scheme_separator = strpos( $path, '://' );

this is the adjusted code to fix it: $scheme_separator = strpos($path ?? '', '://');

2) Backtrace from warning str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated at /wp-includes/functions.php 2189:

here is the code causing the error: $path = str_replace( '\\', '/', $path );

this the adjusted code to fix it: $path = str_replace('\\', '/', $path ?? '');

Hi! Please look further back in the backtrace to discover which function sends a null value through wp_normalize_path(). Both wp_normalize_path() and wp_is_stream() require a string, and anything else could cause issues that are bigger than a deprecation notice.

According to #57580, a number of plugins have added null as the first parameter in add_submenu_page().
