Correct way to run multithreading in a loop

I am running an online shop, and I have a big file with email addresses of customers, but the list is very old, like +15 years old. I bought code from codecanyon that checks the list, but it is very slow.



I tried to make it run multithreaded, but something is very wrong with my code, can you help me out?



The code works, but not the way I want it to. Now it checks the same email x %thread_nr. If I set 10 threads, it checks the same email 10x times.



What is wrong ?



<?php
require_once('email_checker.class.php');

class Task extends Threaded

private $value;

public function __construct(int $i)

$this->value = $i;

public function run()

$file_lines = file('mail.txt');
$emailChecker = new emailChecker; // Make a new instance

foreach ($file_lines as $line)

$response = $emailChecker->check($line);
foreach($response as $result)
echo $result['query'].'-'.$result['success']."n";






$file_lines = file('mail.txt');
# Create a pool of 4 threads
$pool = new Pool(4);
for ($i = 0; $i < 15000; ++$i)

$pool->submit(new Task($i));


while ($pool->collect());

$pool->shutdown();

If I was in that situation I would rework the code so its cleaner, and broken into the smallest functions. Checking that the functions work individually.



I would also test that the code works without multi-threading first, with a small portion of your emails.
