How to Reverse an Array in PHP ?

Answer

To reverse an array in PHP, you can use the built-in `array_reverse()` function.

✐ Examples

1 Reverse Array of Integers

In this example,

We have an array named $intArray containing integers.
We use the array_reverse() function on $intArray to reverse its elements.
We print both arrays to demonstrate the reversal.

PHP Program

<?php
$intArray = [1, 2, 3, 4, 5];
$reversedArray = array_reverse($intArray);
echo 'Original Array: ' . json_encode($intArray) . "\n";
echo 'Reversed Array: ' . json_encode($reversedArray) . "\n";
?>

Output

Original Array: [1,2,3,4,5]
Reversed Array: [5,4,3,2,1]

2 Reverse Array of Strings

In this example,

We have an array named $strArray containing strings.
We use the array_reverse() function on $strArray to reverse its elements.
We print both arrays to demonstrate the reversal.

PHP Program

<?php
$strArray = ['apple', 'banana', 'cherry'];
$reversedArray = array_reverse($strArray);
echo 'Original Array: ' . json_encode($strArray) . "\n";
echo 'Reversed Array: ' . json_encode($reversedArray) . "\n";
?>

Output

Original Array: ['apple','banana','cherry']
Reversed Array: ['cherry','banana','apple']
