Please tell me how to mark the concurrency order of: php curl.

I now have a set of data, which is then requested through the concurrency of curl, but I need to know exactly which piece of data has gone wrong in the past; can this curl concurrency know the order of requests?

for example, I now have a set of data:
$test = [

[
    abc: 1123
],
[
    abc: 3333
],

[
    abc: 444
]

];

when I request these three pieces of data concurrently, I want to know which abc has the wrong value. How to mark this order?

I have printed all kinds of return values. I don"t see any regularity. Do any friends know?

sample code is as follows:
$k = 0;

    

    $query = "{"0":{"extension_number":"101","password":"101"},"1":{"extension_number":"102","password":"102"},"2":{"extension_number":"103","password":"103"},"3":{"extension_number":"104","password":"104"},"4":{"extension_number":"105","password":"105"},"5":{"extension_number":"106","password":"106"},"6":{"extension_number":"107","password":"107"},"7":{"extension_number":"108","password":"108"},"8":{"extension_number":"109","password":"109"},"9":{"extension_number":"110","password":"110"},"access_token":"3371AFB69D4248FDACC742C556916B87"}";
    $query = json_decode($query, 1);

    foreach ($strarr as $key=>$value)
    {
        //10
        for ($i=0; $i<10; $iPP)
        {
            $value[$i]["access_token"] = "F11A7791C2684042BBF62C38AA01D428";

            $ch[$k] = curl_init();
            //url
            curl_setopt($ch[$k], CURLOPT_URL, $url);
            //
            curl_setopt($ch[$k], CURLOPT_HEADER, 1);
            //
            curl_setopt($ch[$k], CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch[$k], CURLOPT_SSL_VERIFYPEER, FALSE);
            curl_setopt($ch[$k], CURLOPT_SSL_VERIFYHOST, FALSE);
            //post
            curl_setopt($ch[$k], CURLOPT_POST, 1);
            curl_setopt($ch[$k], CURLOPT_POSTFIELDS, json_encode($value[$i]));

            curl_multi_add_handle($mh,$ch[$k]);
            $kPP;
        };
    }



    $active = null;
    // 
    do {
        $mrc = curl_multi_exec($mh, $active);
    } while ($mrc == CURLM_CALL_MULTI_PERFORM);

    while ($active && $mrc == CURLM_OK) {
        if (curl_multi_select($mh) != -1) {
            do {
                $mrc = curl_multi_exec($mh, $active);
            } while ($mrc == CURLM_CALL_MULTI_PERFORM);
        }
    }



    // 
    foreach ($ch as $n=>$m)
    {
        $content=curl_multi_getcontent($m);
        file_put_contents("hellow.php", $content."\r\n", FILE_APPEND);
        curl_close($m);
        curl_multi_remove_handle($mh, $m);
    }
    

    curl_multi_close($mh);

when I concurrently request, if any request fails, I need to know exactly which data request failed,
because I need to record the extension_number value of this failed record
