Ticket #31248 on WordPress Trac

[tfrommen]

Originally, I just wanted to replace the missing short description of the get_inline_data function with the comment directly placed above the PHPDoc block. But then I fixed several other things that either my IDE complained about or that I just saw while plowing through the code.

Applying the attached patch does the following:

• add short description to get_inline_data function;
• replace default value '1' of int variable $position in wp_comment_reply function with 1;
• replace empty return; statements for _list_meta_row function with @return string PHPDoc comment with return '';;
• replace default value false of string variable $selected in wp_dropdown_roles function with '';
• replace loose comparison with strict string comparison in wp_dropdown_roles function;
• remove unused (last!) argument $limit_styles in iframe_header function (as well as the according PHPDoc comment);
• remove unused globalization of $current_user variable in iframe_header function;
• add missing @return string PHPDoc comment for get_submit_button function;
• replace default values null of string variable $text and array variable $other_attribues in get_submit_button function with appropriate values (i.e., '' and array());
• add missing @param PHPDoc comments for enqueue_scripts and dismiss_pointers_for_new_users functions.
