How to create a Set of Numbers from 1 to N in PHP ?

Answer

To create a set of numbers from 1 to N in PHP, you can use a loop to add each number to an array and then convert the array to a set using the array_unique function.



✐ Examples

1 Create Set of Numbers from 1 to 5

In this example,

  1. We initialize an empty array named numberArray.
  2. We use a for loop to iterate from 1 to 5 (inclusive).
  3. Inside the loop, we add each number to the array using the [] notation.
  4. We use the array_unique function to remove duplicate elements and convert the array to a set.
  5. The resulting set contains numbers from 1 to 5.

PHP Program

<?php
$numberArray = [];

for ($i = 1; $i <= 5; $i++) {
    $numberArray[] = $i;
}

$numberSet = array_unique($numberArray);

print_r($numberSet);
?>

Output

[1, 2, 3, 4, 5]

2 Create Set of Numbers from 1 to 10

In this example,

  1. We initialize an empty array named numberArray.
  2. We use a for loop to iterate from 1 to 10 (inclusive).
  3. Inside the loop, we add each number to the array using the [] notation.
  4. We use the array_unique function to remove duplicate elements and convert the array to a set.
  5. The resulting set contains numbers from 1 to 10.

PHP Program

<?php
$numberArray = [];

for ($i = 1; $i <= 10; $i++) {
    $numberArray[] = $i;
}

$numberSet = array_unique($numberArray);

print_r($numberSet);
?>

Output

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
