辅助函数需要提前加载，加载方式
创建文件 app/Common/BladeGeneral.php，添加下方2个函数
并在index.php 内引入

index.php

require __DIR__.'/../vendor/autoload.php';
// 在这添加即可，其他代码不动
require __DIR__ . '/../app/Common/BladeGeneral.php';  // 引入

辅助函数

/**
 * 格式化参数格式化成url参数
 */
function ToXml($data){
    if(is_array($data) && count($data) > 0) {
        $xml = "<xml>";
        foreach ($data as $key=>$val) {
            $xml.="<".$key.">".$val."</".$key.">";
        }
        $xml.="</xml>";
        return $xml;
    }
    return "";
}

function ToUrlParams($data){
    $buff = "";
    foreach ($data as $k => $v)
    {
        if($k != "sign" && $v != "" && !is_array($v)){
            $buff .= $k . "=" . $v . "&";
        }
    }
    $buff = trim($buff, "&");
    return $buff;
}
