可以使用maybe_unserialize(get_theme_mods()) 和get_theme_mod() WP功能并遵循以下步骤：

在WP安装的根文件夹中创建一个php文件（路径与wp-load.php).

require_once("wp-load.php");
$r = maybe_unserialize(get_theme_mods());
foreach ($r as $k => $v){
    if(!empty($k)){
        $ListOptions[] = $k;
    }
}
foreach($ListOptions as $option){
    $str = get_theme_mod($option);
    $str = str_replace(\'http://localhost\', \'https://mywebsite.com\', $str);
    $str = str_replace(\'http:\\\\/\\\\/localhost\', \'https:\\\\/\\\\/mediadroit.fr\', $str);
    set_theme_mod($option, $str);
    var_dump(\'|\'.$option.\': \'.get_theme_mod($option).\' ===> \'.$str);
    echo "\\n";
}
