PHP - proxy checker multi-threaded - php

Question

I already made my personal single thread proxy checker using php,but I couldnt make it multi-thread,some days ago,I found one checker using multi-thread on github,can someone help to change it to save the good proxies into a file (ip:port format)?
https://raw.githubusercontent.com/samuel-allan/FastProxyChecker/master/checker.php
What i have tried:
original line 91:
echo json_encode($arr);
changed to:
$json = json_decode($arr);
$good_proxie = $json['arr']['result']['proxy']['ip'];
echo "$good_proxie";

I did not checked it, but think it'll work ^_^
function CheckMultiProxy($proxies, $timeout, $proxy_type)
{
$data = array();
foreach($proxies as $proxy)
{
$parts = explode(':', trim($proxy));
$url = strtok(curPageURL(),'?');
$data[] = $url . '?ip=' . $parts[0] . "&port=" . $parts[1] . "&timeout=" . $timeout . "&proxy_type=" . $proxy_type;
}
$results = multiRequest($data);
$holder = array();
foreach($results as $result)
{
$holder[] = json_decode($result, true)["result"];
}
$arr = array("results" => $holder);
foreach ($arr['results'] as $proxy) {
if ($proxy['success']) {
file_put_contents('YOUR_FILE_HERE', $proxy['proxy']['ip'].':'.$proxy['proxy']['port'].' '.$proxy['proxy']['type'].PHP_EOL, FILE_APPEND);
}
}
echo json_encode($arr);
}
