php - 使用 RectorPHP 将 create_function() 重构为匿名函数

Question

为了兼容 php 7.2，我需要将以下 create_function() 重构为匿名函数：

function bbpp_thankmelater_shortcode_h($atts, $content = NULL) {
    extract(Bbpp_ThankMeLater_Shortcoder::atts(array(
        "email_type" => NULL,
        "comment" => NULL,
        "level" => 1
    ), $atts));
    
    if ($email_type == "text") {
        return str_repeat("*", $level) . " " . $content;
    }
    
    return "<h{$level}>" . $content . "</h{$level}>";
}

for ($i = 1; $i <= 6; $i++) {
    Bbpp_ThankMeLater_Shortcoder::add("h{$i}", create_function("\$atts,\$content", "\$atts[\"level\"]={$i};return bbpp_thankmelater_shortcode_h(\$atts, \$content);"));
}

当使用Rector自动执行此操作时，我收到此错误：

 [ERROR] Could not process "shortcodes/h.php" file, due to:                                        
         "Syntax error, unexpected T_NS_SEPARATOR, expecting ']':1".  

任何想法？提前谢谢您的帮助
