Merge two flat arrays into a 2d array with predefined keys in each row

I want to achieve this kind of array using PHP.

[
  {
    "url": "https://url1.com",
    "code": "BNXl421s"
  },
  {
    "url": "https://url2.com",
    "code": "BNKpt1L2"
  },
  {
    "url": "https://url3.com",
    "code": "BMwhPRih"
  }
]

While i have these arrays :

$urls = 
  [
    "https://url1.com",
    "https://url2.com",
    "https://url3.com"
  ]

$codes= 
  [
    "BNXl421s",
    "BNKpt1L2",
    "BMwhPRih" 
  ]

I tried writing 2 foreach statements but it duplicates results since I had no idea how to achieve that.

Here, try this ( Or the demo here ):

function merge($array1,$array2){
    $output = [];
    for($i = 0; $i < count($array1); $i++){
        $output[$array1[$i]] = $array2[$i];
    }
    return $output;
}


var_dump(merge($urls,$codes));

This will output an array like this

Array(
        "https://url1.com" => "BNXl421s",
        "https://url2.com" => "BNKpt1L2",
        "https://url3.com" => "BMwhPRih"
    )

To make your direct wanted result, try this:

---

function merge($array1,$array2){
    $output = [];
    for($i = 0; $i < count($array1); $i++){
        $output[] = array("url" => $array1[$i], "code" => $array2[$i]);
    }
    return $output;
}
var_dump(merge($urls,$codes));

Same idea, but this output:

array(3) {
  [0]=>
  array(2) {
    ["url"]=>
    string(16) "https://url1.com"
    ["code"]=>
    string(8) "BNXl421s"
  }
  [1]=>
  array(2) {
    ["url"]=>
    string(16) "https://url2.com"
    ["code"]=>
    string(8) "BNKpt1L2"
  }
  [2]=>
  array(2) {
    ["url"]=>
    string(16) "https://url3.com"
    ["code"]=>
    string(8) "BMwhPRih"
  }
}
