通过延迟将循环过程分解成部分，需要建议

Question

i wanted to break down a process (loop) into some parts, for example if have 128 emails to send :

function subs_emails(){    
    $subscribers = //find subscribers

    if(!empty($subscribers )){
        foreach($subscribers as $i => $subscriber){
            sendEmail($subscriber->id);
            if($i % 15 == 0){ //<-- send email per 15
                sleep(60); //to pause the process for 60 seconds 
            }
        }
        return true;
    }else{
        return false;
    }
}

will this works ?? or is there any other "better approach" solution ?? need advice please

thanks

Answer 1

The usual approach would be to send only a few emails at once and mark the sent ones on the background(via database flag sent=1 for example)

Then call the script every few minutes via a cronjob

This way you dont run into problems with php timeouts when sending emails to a lot of subscribers
