Error in PHP Compatibility

  • I’d like to update out website to the most recent version of PHP (7.3), and when I ran a compatibility check with the PHP Compatibility Checker plugin, this plugin (Replace Default Words) came up with the following errors:

    FILE: /home/eugene23/public_html/wp-content/plugins/replace-default-words/replace-default-words.php
    ———————————————————————————————————————————————
    FOUND 4 ERRORS AFFECTING 2 LINES
    ———————————————————————————————————————————————
    83 | ERROR | Function mysql_escape_string() is deprecated since PHP 5.3 and removed since PHP 7.0; Use mysqli::real_escape_string() instead
    83 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0; Use mysqli instead
    84 | ERROR | Function mysql_escape_string() is deprecated since PHP 5.3 and removed since PHP 7.0; Use mysqli::real_escape_string() instead
    84 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0; Use mysqli instead

    Please let me know if/how this will affect my update. Will the plug-in still work? Is there anything I can do to fix it? Or do I need to find a similar plug-in to use instead? Thank you.
