In PHP, what are the implications of comparing percentage values with currency values when finding the maximum value in an array?

When comparing percentage values with currency values in PHP, it's important to note that percentage values are typically represented as decimals (e.g., 0.5 for 50%) while currency values are represented as floats or integers. When finding the maximum value in an array containing both percentage and currency values, it's crucial to convert the percentage values to their equivalent currency values before comparison to ensure accurate results. 

// Sample array containing percentage and currency values
$values = [0.25, 50.00, 0.75, 100.00];

// Convert percentage values to currency values
foreach ($values as $key => $value) {
    if ($value < 1) {
        $values[$key] = $value * 100; // Convert percentage to currency
    }
}

// Find the maximum value in the array
$maxValue = max($values);

echo "The maximum value in the array is: $maxValue";
