Merge multiple array in php laravel

Question

Let us say I have a set of data of the first name

first name : `{ "abc","bvd","jhhg", "jju","jju"}`
Last name : `{ "hhh","uuu","tre", "vvg","yyy"}`
Age : `{ "44","33","34", "34,"65"}`

I want the result to return as

{
"fname" : "abc",
"lname" : "hhh",
"age" : "44"
},
{
"fname" : "bvd",
"lname" : "uuu",
"age" : "33"
},
{
"fname" : "jhhg",
"lname" : "tre",
"age" : "34"
}

How to do it in php / laravel

I have achieved the result but the response is too slow

  $cart = array();

   for($i = 1;$i<=($qty);$i++)
   {

       $fnames = CreateFirstName::all()->random(1);

       $fname = ($fnames[0]->fname);

       $images = CreateImageName::all()->random(1);

       $image = ($images[0]->imagelocation);


       $lnames = CreateLastName::all()->random(1);
       $lname = ($lnames[0]->lname);

       $cart[] = [
           'id' => $images[0]->id,
           'fname' => mb_substr($fname, 0, 10),
           'lname' => mb_substr($lname, 0, 10),
           'age' => rand(18,43),
           'city' => $region_name,
           'image' => $image

       ];

   }


   $collection = collect($cart);

The response is coming more than 20000 ms on the server or local enviroment

Also, please add a little more detail: should only the first three datasets be returned? Or is jju somehow not permitted to be included? — user8034901

@kobid, do you need just 3 elements or all of them to returned in the way you have shared in expected output? — Danyal Sandeelo

As an alternative to the accepted answer you could also use array_map.

array_map will essentially take one or more arrays and iterate over them by passing the current iteration of each array to the callback function:

$people = array_map(function ($fname, $lname, $age) {
    return [
        'fname' => $fname,
        'lname' => $lname,
        'age'   => $age,
    ];
}, $firstNames, $lastNames, $ages);

You could then make it even shorter by using compact

$people = array_map(function ($fname, $lname, $age) {
    return compact('fname', 'lname', 'age');
}, $firstNames, $lastNames, $ages);

I assume the size of all the 3 arrays is same

$finalArray = array();
for($i=0;$i<count($firstArray);$i++){
    $finalArray[] = array("fname"=>$firstArray[$i], "lname"=>$lastArray[$i],"age"=>$ageArray[$i]);
}

$finalArray has what you have.

That will not return OP's desired result though, but all elements from the arrays

The "I want the result to return as" part still only has three elements
