format_for_editor

WordPress Version: 4.5

/**
 * Formats text for the editor.
 *
 * Generally the browsers treat everything inside a textarea as text, but
 * it is still a good idea to HTML entity encode `<`, `>` and `&` in the content.
 *
 * The filter {@see 'format_for_editor'} is applied here. If `$text` is empty the
 * filter will be applied to an empty string.
 *
 * @since 4.3.0
 *
 * @see _WP_Editors::editor()
 *
 * @param string $text           The text to be formatted.
 * @param string $default_editor The default editor for the current user.
 *                               It is usually either 'html' or 'tinymce'.
 * @return string The formatted text after filter is applied.
