How to Convert a Set of Integers to a Set of Strings in PHP - Step by Step Examples

How to Convert a Set of Integers to a Set of Strings in PHP ?

Answer

In PHP, you can iterate over each element in the set and convert it to a string using type casting or the strval() function.


✐ Examples

1 Convert a Set of Integers to a Set of Strings using Type Casting

In this example,

  1. We have a set of integers named $intSet.
  2. We create an empty set named $stringSet.
  3. We iterate over each element of $intSet using a foreach loop.
  4. Inside the loop, we convert each integer element to a string using type casting and add it to the $stringSet.

PHP Program

<?php
$intSet = new DsSet([1, 2, 3, 4, 5]);
$stringSet = new DsSet();
foreach ($intSet as $num) {
    $stringSet->add((string)$num);
}
var_dump($stringSet);
?>

Output

object(Ds\Set)#2 (5) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
  [3]=>
  string(1) "4"
  [4]=>
  string(1) "5"
}

2 Convert a Set of Integers to a Set of Strings using strval() Function

In this example,

  1. We have a set of integers named $intSet.
  2. We create an empty set named $stringSet.
  3. We iterate over each element of $intSet using a foreach loop.
  4. Inside the loop, we convert each integer element to a string using the strval() function and add it to the $stringSet.

PHP Program

<?php
$intSet = new DsSet([1, 2, 3, 4, 5]);
$stringSet = new DsSet();
foreach ($intSet as $num) {
    $stringSet->add(strval($num));
}
var_dump($stringSet);
?>

Output

object(Ds\Set)#2 (5) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
  [3]=>
  string(1) "4"
  [4]=>
  string(1) "5"
}
