Multi-threading php in the module

[QuentinJou]

Hello,

I am currently developing a module that imports products into Prestashop but it takes a long time to process so I would like to do it alongside running prestashop/in the background. Is it possible to do this? if yes how can i do?

Thank you for the help

Multithreading and php. A nightmare  
But there are different solutions like pthreads or parallel. 

But do you really have to run the import in the background? php and prestashop can handle multiple requests at a time, so you can still work in your shop, while the import is handled in another process.

Thank you for that answer. I see that...😅

I tried in parallel. It works in terminal but not in my webserver so I don't know if we can do with it?

For the multiple process of prestashop is it activated basic? I'm running my function in a back office hook like that, but can't do anything else beside it. Is it the good process ? How can I do this?

public function hookDisplayBackOfficeHeader()
    {
        if (Tools::getIsSet('initProduct')) {
        	$this->initAll();
        }

        $redirect = $_SERVER['REQUEST_URI'] . '&initProduct=1';
        $this->context->smarty->assign(
            [
                'redirect' => $redirect,
            ]
        );
    }

 

(sorry for my bad english)

You can configure how many php processes your webserver is allowed to start. Read here: https://www.php.net/manual/en/install.fpm.configuration.php 

Depending on your php configuration it should be pm.max_children which should be larger than 1. Or like it is written here

Inside this file, the most important setting is the pm.max_children setting. It must be greater than the max number of concurrent users you want to simulate during the bench.
