Question

Goal:
User only selects one, only one option at a given time for the denomination, either some value of Nickels only,
some value of Dimes only, or some value of Quarters only.

Problems: Currently the code only defaults to Nickels only?

Pre-existing condtion:
If I select a different denomination, for example, Quarters only, I only get the values for Nickels, the same applies for Dimes?

Code Snippet:

if($denomination["Nickels"] != NULL)

{
$value = $denomination["Nickels"];
echo $value . " is the value of selected Nickels";
}

else if ($denomination["Dimes"] != NULL)
{
$value = $denomination["Dimes"];
echo $value . " is the value of  selected Dimes";
}

else if ($denomination["Quarters"] != NULL)
{
$value = $denomination["Quarters"];
echo  $value . "is the value of selected Quarters";
} 

Answer 1

To make it short:

<?php
$value = array_shift(array_filter($denomination));
echo  $value . "is the value of selected Quarters";

With this you don’t have to put in a if for every new element.
