How to create an associative array from two arrays?

Question

I have two arrays one for keys and another for values. The values array is an array of array.

Keys array:

$keyArray = array("clientId","clientName","clientAdsress","clientPhone");

Values array:

$valuesArray = array(
                "0"=>array("1001","aaaaa","ddddddd","22222222"),
                "1"=>array("1002","bbbbbb","ddddddd","11111111"),
                "2"=>array("1003","ccccc","ddddddd","33333333")
              );

Expected Output:

$finalData = array(
                    "clientId"=>array("1001","1002","1003"),
                    "clientName"=>array("aaaaa","bbbbbb","ccccc"),
                    "clientAdsress"=>array("ddddddd","ddddddd","ddddddd"),
                    "clientPhone"=>array("22222222","11111111","33333333")
                  );

I have tried this code:

$finalData = array();
for($i=0;$i<count($keyArray);$i++){

    for($j=0;$j<count($valuesArray);$j++){
        $rowArray = $valuesArray[$j];
       $finalData[$keyArray[$i]] = array($rowArray[$i]);
    }
}

echo '<pre>';print_r($finalData);echo '</pre>';

Output:

Array
(
    [clientId] => Array
        (
            [0] => 1003
        )

    [clientName] => Array
        (
            [0] => ccccc
        )

    [clientAdsress] => Array
        (
            [0] => ddddddd
        )

    [clientPhone] => Array
        (
            [0] => 33333333
        )

)

I am getting the last values of arrays. How can I get my expected output?

A simple foreach solution:

<?php

$keyArray = array("clientId", "clientName", "clientAdsress", "clientPhone");
$valuesArray = array(
    "0" => array("1001", "aaaaa", "ddddddd", "22222222"),
    "1" => array("1002", "bbbbbb", "ddddddd", "11111111"),
    "2" => array("1003", "ccccc", "ddddddd", "33333333")
);
$expected = array(
    "clientId" => array("1001", "1002", "1003"),
    "clientName" => array("aaaaa", "bbbbbb", "ccccc"),
    "clientAdsress" => array("ddddddd", "ddddddd", "ddddddd"),
    "clientPhone" => array("22222222", "11111111", "33333333")
);

$result = [];
foreach ($keyArray as $key => $keyName) {
    foreach ($valuesArray as $value) {
        $result[$keyName][] = $value[$key];
    }
}

var_dump($result === $expected);

Output for 7.1.25 - 7.3.2
