How to get Sub Array in PHP - Step by Step Examples

How to get Sub Array in PHP ?

To get a sub-array in PHP, you can use the `array_slice` function.

In this example,

We create an integer array named $numbers with some values.
We then use the array_slice function to get a sub-array from index 2 to index 4 (exclusive).
The array_slice function returns a new array with the specified range.
Finally, we print the sub-array.

<?php
$numbers = [1, 2, 3, 4, 5];
$subArray = array_slice($numbers, 2, 2);
echo 'Sub-array: ' . json_encode($subArray);
?>

Sub-array: [3,4]

In this example,

We create a string array named $colors with some values.
We then use the array_slice function to get a sub-array from index 1 to index 3 (exclusive).
The array_slice function returns a new array with the specified range.
Finally, we print the sub-array.

<?php
$colors = ['red', 'green', 'blue', 'yellow', 'orange'];
$subArray = array_slice($colors, 1, 2);
echo 'Sub-array: ' . json_encode($subArray);
?>

Sub-array: ["green","blue"]
