app目录下创建一个名为helpers.php的文件(app/helpers.php)并编辑其内容如下

## app\\helpers.php ##

<?php
    // 全局函数
    /**
     * 三个一组相加
     */
    if (!function_exists('sgsyz')) {
        
        function sgsyz($twowthrewNinetenw)
        {
        
            $n = 0;
            $y = 0;
            for ($i = 0; $i < count($twowthrewNinetenw); $i++) {
        
                $n++;
                $y++;
    
                if ($n == 3) {
        
                    $wu[] = $twowthrewNinetenw[$i];
                    $wu[] = $twowthrewNinetenw[$i - 1];
                    $wu[] = $twowthrewNinetenw[$i - 2];
                    rsort($wu);
                    $sor = $wu[0] + $wu[1] + $wu[2];
    
                    $one[$y - 3] = $sor;
                    $one[$y - 2] = $sor;
                    $one[$y - 1] = $sor;
    
                    $wu = array();
                    $n = 0;
                }
            }
            return $one;
        }
    }
    
    
    if (! function_exists('success')) {
        
        /**
         * @param array  $data
         * @param string $msg
         * @param int    $code
         *
         * @return array
         */
        function success($data = [], $msg = CommonConst::SUCCESS_CODE_MSG, $code = CommonConst::SUCCESS_CODE)
        {
        
            return [
                'code' => $code,
                'message'  => $msg,
                'data' => $data
            ];
        }
    }
    
    if (! function_exists('error')) {
        
        /**
         * @param int    $code
         * @param string $msg
         * @param array  $data
         *
         * @return array
         */
        function error($code = CommonConst::ERROR_CODE, $msg = CommonConst::ERROR_CODE_MSG, $data = [])
        {
        
            return [
                'code' => $code,
                'message'  => $msg,
                'data' => $data
            ];
        }
    }

要让应用能够正确找到 helpers.php 文件，还要修改项目根目录下 composer.json 的 autoload 配置：

## composer.json ##

composer.json
        "autoload": {
            "psr-4": {
                "App\\": "app/"
            },
            "classmap": [
                "database/seeds",
                "database/factories"
            ],
            "files": [
                "app/helpers.php"
            ]
        },

composer dump-autoload
    # 或
    composer dumpautoload

应用

# 找个控制器里放函数即可因为是全局的不用调用什么的
    sgsyz($twowthrewNinetenw)
    
    return response()->json(error('4001','error'));
