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

Answer

To convert a set of strings to a set of floats in PHP, you can use the array_map() function along with the floatval() function to transform each string value into its corresponding float value.


✐ Examples

1 Convert a Set of Strings ["1.1", "2.2", "3.3"] to Floats

In this example,

  1. First, we create an array of strings named $stringArray1 with values ["1.1", "2.2", "3.3"].
  2. Next, we use the array_map() function on $stringArray1 to transform each string value into its corresponding float value. We pass the floatval() function as the callback to array_map().
  3. We store the result of this transformation in a new array called $floatArray1.
  4. Finally, we convert the array to a set using the array_unique() function to remove duplicate values.

PHP Program

<?php 
$stringArray1 = ["1.1", "2.2", "3.3"];
$floatArray1 = array_unique(array_map("floatval", $stringArray1));
print_r($floatArray1);
?>

Output

[1.1, 2.2, 3.3]

2 Convert a Set of Strings ["4.5", "5.6", "6.7"] to Floats

In this example,

  1. First, we create an array of strings named $stringArray2 with values ["4.5", "5.6", "6.7"].
  2. Next, we use the array_map() function on $stringArray2 to transform each string value into its corresponding float value. We pass the floatval() function as the callback to array_map().
  3. We store the result of this transformation in a new array called $floatArray2.
  4. Finally, we convert the array to a set using the array_unique() function to remove duplicate values.

PHP Program

<?php 
$stringArray2 = ["4.5", "5.6", "6.7"];
$floatArray2 = array_unique(array_map("floatval", $stringArray2));
print_r($floatArray2);
?>

Output

[4.5, 5.6, 6.7]
