Dealing with European-style prices in PHP? Learn how to convert formats, calculate discounts, and localize outputs for international audiences! 🌍 #PHP #Programming #Localization

Problem Scenario

You’re given:

   Original Price: "1.234,56" (1,234.56 in standard format)
   Discounted Price: 987.65 (already in standard decimal format)

You need to:

1. Convert the original price to a standard decimal format for calculations.
2. Calculate the discount percentage.
3. Output the results in European-style format with appropriate separators.
4. Add new lines (\n) for command-line or text-based outputs.

Rules Summary:

1. Decimal Separator (,):

   • Used to separate whole numbers from fractional parts.
   • Example:
     • 100.25 (English) → 100,25 (German).

2. Thousand Separator (.):

   • Used to group numbers into thousands, millions, billions, etc.
   • Example:
     • 10,000,000 (English) → 10.000.000 (German).

PHP Code Solution

Here’s the PHP script to achieve this:

<?php
// European-style original price and standard decimal discounted price
  $originalPrice = "1.234,56"; // European format
  $discountedPrice = 987.65;    // Standard decimal format

// Convert the original price to standard decimal format
  $originalPrice = floatval(str_replace(',', '.', str_replace('.', '', $originalPrice)));

// Calculate the discount percentage
  $discountPercentage = (($originalPrice - $discountedPrice) / $originalPrice) * 100;

// Format to 2 decimal places
  $discountPercentage = round($discountPercentage, 2);

// Output results with new lines
  echo "Original Price: €" . number_format($originalPrice, 2, ',', '.') . "\n";
  echo "Discounted Price: €" . number_format($discountedPrice, 2, ',', '.') . "\n";
  echo "Discount Percentage: " . number_format($discountPercentage, 2, ',', '.') . "%\n";
?>

Step-by-Step Explanation

1. Handling European-Style Prices

The Original Price ("1.234,56") uses a comma as a decimal separator and a period for thousands. To make it usable for calculations:
    Remove the thousands separator (.).
     Replace the decimal comma (,) with a period (.)..

$originalPrice = floatval(str_replace(',', '.', str_replace('.', '', $originalPrice)));

2. Calculating the Discount Percentage

---

Here’s the code:

$discountPercentage = (($originalPrice - $discountedPrice) / $originalPrice) * 100;$discountPercentage = round($discountPercentage, 2);

3. Formatting the Output
To display the results in European-style formatting (e.g., €1.234,56), use number_format():

number_format($value, 2, ',', '.');

For example:

echo "Original Price: €" . number_format($originalPrice, 2, ',', '.') . "\n";

4. Adding New Lines

To ensure proper formatting for plain text output, use \n for new lines:

echo "Discount Percentage: " . number_format($discountPercentage, 2, ',', '.') . "%\n";

Example Output
If you run the script with the input values:

   Original Price: "1.234,56"
   Discounted Price: 987.65

You’ll get the following output:

Copycode>Original Price: €1.234,56Discounted Price: €987,65Discount Percentage: 20,00%
