How to Join Arrays in PHP


How to Join Arrays in PHP ?

Answer

To join arrays in PHP, you can use the array_merge function, which merges the elements of one or more arrays together.



✐ Examples

1 Join Two Indexed Arrays

In this example,

  1. We create two indexed arrays named $arr1 and $arr2 with a few elements.
  2. We use the array_merge function to merge the two arrays into a new array named $result.
  3. Finally, we print the resulting array to standard output.

PHP Program

<?php
$arr1 = array("apple", "banana");
$arr2 = array("cherry", "date");
$result = array_merge($arr1, $arr2);
print_r($result);
?>

Output

Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
    [3] => date
)

2 Join Two Associative Arrays

In this example,

  1. We create two associative arrays named $arr1 and $arr2 with key-value pairs.
  2. We use the array_merge function to merge the two arrays into a new array named $result.
  3. Finally, we print the resulting array to standard output.

PHP Program

<?php
$arr1 = array("a" => "apple", "b" => "banana");
$arr2 = array("c" => "cherry", "d" => "date");
$result = array_merge($arr1, $arr2);
print_r($result);
?>

Output

Array
(
    [a] => apple
    [b] => banana
    [c] => cherry
    [d] => date
)
