如何避免在不更改php.ini max_execution_time的情况下超过Laravel 60秒的最大执行时间

我的代码有一个问题，我将导出到包含100000多个数据的CSV，在这里我使用了

chunk

2次，第一次是

getData

变量，其中该变量在另一个类中使用

AssetRepository

函数，另一次是我在

foreach

时的使用，如果使用

限制加载1000个数据

，则可以导出数据。是否可以在

php.ini

上加载数据而不更改

max\u execute\u time

，并且仅使用

chunk

？ 如果可以，我如何优化我的代码

在本例中，我使用的是PostgreSQL

下面是

AssetRepository.php

class AssetRepository
{
    public $query = null;
    private $trashed = false;

    public static function query()
    {
        $repo = new AssetRepository();
        $repo->query = DB::table('assets as a')
        ->select(
            DB::raw("distinct a.id"),

            "a.duration as duration",
            DB::raw("COALESCE( NULLIF(a.qr_code,'') , 'QR Code Not Set' ) as qr_code"),

如果需要，请忽略

AssetController.php

这是我的代码中使用的查询

最好异步执行这些长时间运行的任务。在拉威尔，你可以用它。当队列在CLI上运行时，您可以为此配置不同的

max\u execution\u time

。如果希望保持执行时间不变，则应尝试将正在执行的任务拆分为多个部分。如果这些部分中的每一部分都不超过1分钟，那么您就可以开始了。

您可以调用

set\u time\u limit（0）

从其余的执行中删除时间限制，或者在循环的每次迭代（例如）中调用

set\u time\u limit（n）

将计时器重置n秒以上

---

也许这个查询返回的元素太多了，PHP大部分时间都只是在它们周围包装一个

集合

对象。如果您想查看查询本身花费了多少时间，可以直接在

PostgreSQL Server

、控制台（

php artisan tinker

）上运行它，或者在代码中使用

DB:：listen

公共函数exportAll（请求$Request）
{
//PHP>=7.4.0
DB:：listen（fn（$query）=>dump（$query->sql，$query->bindings，$query->time））；
//PHP<7.4.0
DB:：listen（函数（$query）{dump（$query->sql，$query->bindings，$query->time）；}）；
...
}

如果出现

集合

包装问题，请尝试使用

懒散集合

。它从Laravel 6.0开始提供。您可以通过调用

$data->cursor（）

而不是

$data->get（）

来使用它

LazyCollection

基本上是一个对象，您可以在其上迭代并使用一些

Collection

方法。它们允许您处理数据，而无需为X行构建一个大的

集合




我将重新发布您的
exportAll
函数，其中包含一些我认为会对性能产生积极影响的更改
