How to get Subset from a Set in PHP ?

Answer

To get a sub Set in PHP, you can use the array_slice function.

✐ Examples

1 Get Sub Set with Items

In this example,

We define an array named mySet containing elements of a specific type.
We specify the range of indices to extract the sub Set.
We use the array_slice function with the specified range to get the sub Set.

PHP Program

<?php
// Define array with items
$mySet = ['apple', 'banana', 'orange', 'grape', 'melon'];

// Get sub Set with items
$subSet = array_slice($mySet, 1, 3);
echo 'Sub Set with items: ' . json_encode($subSet);
?>

Output

Sub Set with items: ["banana","orange","grape"]

2 Get Sub Set from Empty Set

In this example,

We define an empty array named mySet.
We attempt to get a sub Set from the empty array, which results in an empty sub Set.

PHP Program

<?php
// Define empty array
$mySet = [];

// Get sub Set from empty array
$subSet = array_slice($mySet, 1, 3);
echo 'Sub Set from empty array: ' . json_encode($subSet);
?>

Output

Sub Set from empty array: []
