How to Copy an Array in PHP ?

Answer

To copy an array in PHP, you can use the array_slice() function or assign the array directly.

✐ Examples

1 Copying an Array using array_slice()

In this example,

We create an array named $array1 with elements.
We then use array_slice($array1, 0) to create a copy of $array1 and store it in $array2.
array_slice() returns a copy of the array.

PHP Program

<?php 
$array1 = [1, 2, 3, 4, 5];
$array2 = array_slice($array1, 0);
echo 'Array 1: ' . print_r($array1, true) . "\n";
echo 'Array 2 (copy of Array 1): ' . print_r($array2, true) . "\n";
?>

Output

Array 1: Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)
Array 2 (copy of Array 1): Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)

2 Copying an Array by Assignment

In this example,

We create an array named $array1 with elements.
We then assign $array1 to $array2 directly.
This assigns the same array to $array2.

PHP Program

<?php 
$array1 = [1, 2, 3, 4, 5];
$array2 = $array1;
echo 'Array 1: ' . print_r($array1, true) . "\n";
echo 'Array 2 (copy of Array 1): ' . print_r($array2, true) . "\n";
?>

Output

Array 1: Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)
Array 2 (copy of Array 1): Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)
