如何在php中连接两个数组？ [重复]

I want to concatenate two arrays like this:

$cars=array("Volvo","BMW","Toyota");
$speed=array("210","220","330");
$merge=array_merge($cars,$speed);

Expected output:

array(
    0=>Volvo 210
    1=>BMW 220 
    2=>Toyota 330
)

</div>

You can also try this simplest one. Here we are using array_map to achieve desired output

Try this code snippet here

<?php

$cars = array('Volvo', 'BMW', 'Toyota');
$speed = array('210', '220', '330');

$result = array_map(function($car, $speed) {
    return $car . ' ' . $speed;
}, $cars, $speed);

var_dump($result);

1st : Loop the first array using foreach

2nd : concatenate the both variable

3rd : Push the value into new array .

<?php

$cars=array("Volvo","BMW","Toyota");
$speed=array("210","220","330");
$new_array =array();

foreach($cars as $key=>$c)
{
    $new_array[]=$c.' '.$speed[$key];   
}

print_r($new_array);

?>

Note : Above code will work only when both array have same count of elements and same index .

This will put all values into one array.

   <?php 
       $cars=array("Volvo","BMW","Toyota");
       $speed=array("210","220","330");
       $merge=[];
       for ($x = 0; $x < sizeof($cars); $x++) {
          array_push($merge,$cars[$x] .' '. $speed[$x]);
       } 
    ?>

EDIT As I have recieved a downvote for some unknown reason I will explain my answer.

Loop through one array in this case the cars array, then add a concatination of the two arrays to the merge array.

This code will achieve the same result as the accepted answer.

There is no method in php for such a scenario, but you can do this:

$cars=array("Volvo","BMW","Toyota");    
$speed=array("210","220","330");

$newArr = array();

foreach($cars as $cKey => $cVal){    
  $newArr[] = $cVal.' '.$speed[$cKey];    
}

print_r($newArr);

Combine both array and push into another array. See example:

$speed=array("210","220","330");
$merge=array_combine($cars,$speed);

$arr= array(); // new array for storing desired data

foreach($merge as $k=>$v){
$arr[] = $k .' '.$v;
}
print_r($arr);

Output: 
Array
(
    [0] => Volvo 210
    [1] => BMW 220
    [2] => Toyota 330
)
