Deprecated: strpos(): Passing null to parameter

[calliko]

There is a warning in the admin panel:
Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in A:\OSPanel\home\homewp.ru\wp-includes\functions.php on line 7303

With these changes there will be no error:
function wp_is_stream( $path ) {
/*new code start*/

if($path===null){

return false;

}

/*new code end*/

$scheme_separator = strpos( $path, ':' );

if ( false === $scheme_separator ) {

$path isn't a stream.
return false;

}

$stream = substr( $path, 0, $scheme_separator );

return in_array( $stream, stream_get_wrappers(), true );

}

Hi there and welcome to WordPress Trac!

This has been reported a few times in the past and we're trying to keep all the discussions in one place. Hence I am closing this as a duplicate of #57580.

Also worth noting that we generally do not want to paper over deprecation warnings like this by adding sanity checks in low-level functions. These kinds of issues should ideally be addressed at the root.
