We declare a float array named $floatArray with predefined values using array literal notation.
We print the array to the output to demonstrate the initialization.

<?php 
$floatArray = [1.2, 3.4, 5.6];
print_r('Float Array:');
print_r($floatArray);
?>

Float Array:Array
(
    [0] => 1.2
    [1] => 3.4

)
