How to Declare a Float Array in PHP ?

To declare a float array in PHP, you can use array literal notation or the array() function.

In this example,

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
    [2] => 5.6
)

In this example,

We declare an empty float array named $emptyFloatArray using the array() function without any elements.
We print the array to the output to demonstrate the declaration.

<?php 
$emptyFloatArray = array();
print_r('Empty Float Array:');
print_r($emptyFloatArray);
?>
