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

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

Answer

In PHP, you can convert a set of strings to a set of integers by iterating through the set and using the intval() function to convert each string to an integer.

✐ Examples

1 Convert a Set of Strings to a Set of Integers using intval()

In this example,

We have a set named $stringSet1 containing the elements '1', '2', '3', '4', '5'.
We iterate through $stringSet1 and use the intval() function to convert each string element to an integer.
We add the converted integers to a new set named $intSet1.
We print the resulting $intSet1 to the console.

PHP Program

<?php 
$stringSet1 = new Set(['1', '2', '3', '4', '5']);
$intSet1 = new Set();
foreach ($stringSet1 as $str) {
    $intSet1->add(intval($str));
}
print_r($intSet1);
?>

Output

Set {
  1,
  2,
  3,
  4,
  5,
}

2 Convert a Set of Strings to a Set of Integers using array_map() and intval()

In this example,

We have a set named $stringSet2 containing the elements '10', '20', '30', '40', '50'.
We use the array_map() function along with intval() to convert each string element to an integer.
We create a new set named $intSet2 containing the converted integers.
We print the resulting $intSet2 to the console.

PHP Program

<?php 
$stringSet2 = new Set(['10', '20', '30', '40', '50']);
$intSet2 = new Set(array_map('intval', $stringSet2->toArray()));
print_r($intSet2);
?>

Output

Set {
  10,
  20,
  30,
  40,
  50,
}
