PHP Program to merge two array using array_merge() function

How to merge two arrays?

In this program, we are going to merge two arrays. Here we are using the built-in function array_merge() to merge the array. For example, if the two arrays are [4,5,8,9] and [9,7,6,3] after merging these arrays the result will be [4,5,8,9,9,7,6,3]

Syntax of function array_merge()


array_merge(array1, array2, array3, ...)
 

 

How to merge two arrays using PHP?

To merge two arrays first we have to initialize the arrays arr1 and arr2 with values. Then we have to use the built-in function array_merge() with arguments arr1 and arr2 to merge the arrays. After that we can print the elements in the arrays arr1[] as the first array, arr2[] as the second array, and arr3[] as the merged array

ALGORITHM

Step 1: Initialize the arrays arr1 and arr2 with values

Step 2: Use the built-in function array_merge(arr1,arr2) to merge the arrays

Step 3: Print the elements in the arrays arr1[] as the first array, arr2[] as the second array, and arr3[] as the merged array

PHP Source Code

                                          <?php
$arr1 = array(1, 2, 3, 4, 5);
$arr2 = array(6, 7, 8, 9, 2);
$arr3 = array_merge($arr1, $arr2);
echo "First array: \n";
foreach ($arr1 as $x) {
    echo "$x ";
}
echo "\nSecond array: \n";
foreach ($arr2 as $x) {
    echo "$x ";
}
echo "\nArray after merge: \n";
foreach ($arr3 as $x) {
    echo "$x ";
}
?>
                                      

OUTPUT

First array:
1 2 3 4 5
Second array:
6 7 8 9 2
Array after merge:
1 2 3 4 5 6 7 8 9 2
