PHP deprecated: strstr(): Passing null to parameter

PHP 8.1, Open-Search 4.1.0

I’m getting multiple PHP Deprecated warnings when using Open Search:

[16-Jan-2024 16:31:44 UTC] PHP Deprecated: strstr(): Passing null to parameter #1 ($haystack) of type string is deprecated in /.../wp-includes/functions.php on line 1153
[16-Jan-2024 16:31:44 UTC] PHP Deprecated: stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /.../wp-includes/functions.php on line 1160
[16-Jan-2024 16:31:44 UTC] PHP Deprecated: stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /.../wp-includes/functions.php on line 1163

[16-Jan-2024 16:31:44 UTC] PHP Deprecated: str_contains(): Passing null to parameter #1 ($haystack) of type string is deprecated in /.../wp-includes/functions.php on line 1173

Backtrace:

0 /wp-content/plugins/open-search-document/includes/functions.php(52): add_query_arg('s', 'searchTerms', NULL)
1 /wp-content/plugins/open-search-document/templates/open-search-document.php(8): OpenSearchDocument\feed_url_template('atom')

Root cause:

Incorrect use of bloginfo() which always returns NULL

Fix:

Replace by get_bloginfo() in includes/function.php:

$feed_url_template = add_query_arg( 's', 'searchTerms', get_bloginfo( "{$feed}_url" ) );

Thanks for the fix,
Marc
