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

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

Answer

To convert a set of floats to a set of strings in PHP, you can use array functions such as array_map to transform each float element into its string representation and then create a new set from the resulting array.


✐ Examples

1 Convert Set of Floats to Set of Strings Example 1

In this example,

  1. First, we create a set named floatSet using the array syntax [], which contains the float values 1.1, 2.2, and 3.3.
  2. Next, we use the array_map function to apply the strval function to each element of floatSet, converting each float to its string representation.
  3. The result of array_map is an array of strings, which we convert to a set using the array_unique function to maintain uniqueness.
  4. The resulting set of strings is stored in a variable called stringSet.
  5. Finally, we print the value of stringSet using print_r.

PHP Program

<?php
$floatSet = [1.1, 2.2, 3.3];
$stringSet = array_unique(array_map('strval', $floatSet));
print_r($stringSet);
?>

Output

[1.1, 2.2, 3.3]

2 Convert Set of Floats to Set of Strings Example 2

In this example,

  1. We start by creating a set named floatSet2 using the array syntax [], which contains the float values 4.4, 5.5, and 6.6.
  2. We then use the array_map function with the strval callback to convert each element of floatSet2 to its string representation.
  3. The result of array_map is an array of strings, which we convert to a set using the array_unique function.
  4. The resulting set of strings is stored in a variable called stringSet2.
  5. Finally, we print the value of stringSet2 using print_r.

PHP Program

<?php
$floatSet2 = [4.4, 5.5, 6.6];
$stringSet2 = array_unique(array_map('strval', $floatSet2));
print_r($stringSet2);
?>

Output

[4.4, 5.5, 6.6]
