Laravel配置全局公共函数的方法步骤

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'));
