ProgramGuruTo 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.
In this example,
$stringArray1 with values ["1.1", "2.2", "3.3"].array_map() function on $stringArray1 to transform each string value into its corresponding float value. We pass the floatval() function as the callback to array_map().$floatArray1.array_unique() function to remove duplicate values.<?php
$stringArray1 = ["1.1", "2.2", "3.3"];
$floatArray1 = array_unique(array_map("floatval", $stringArray1));
print_r($floatArray1);
?>[1.1, 2.2, 3.3]
In this example,
$stringArray2 with values ["4.5", "5.6", "6.7"].array_map() function on $stringArray2 to transform each string value into its corresponding float value. We pass the floatval() function as the callback to array_map().$floatArray2.array_unique() function to remove duplicate values.<?php
$stringArray2 = ["4.5", "5.6", "6.7"];
$floatArray2 = array_unique(array_map("floatval", $stringArray2));
print_r($floatArray2);
?>[4.5, 5.6, 6.7]
