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>

Answer 1

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);
