Dollar buy sell php script free download .Dollar buy sell WordPress Theme
Here’s a simple PHP script for a Dollar Buy/Sell system. It allows users to input an amount in dollars and get the equivalent in another currency (e.g., PHP or any other). It includes basic conversion logic.
Features:
âī¸ Live exchange rate fetching (optional)
âī¸ Manual exchange rate input (if no API is used)
âī¸ Simple UI with form submission
PHP Script (index.php)
<?php
// Function to fetch live exchange rate (optional)
function getExchangeRate($from_currency, $to_currency) {
$apiKey = 'YOUR_API_KEY_HERE'; // Replace with a real API key
$url = "https://api.exchangerate-api.com/v4/latest/$from_currency";
$response = file_get_contents($url);
if ($response) {
$data = json_decode($response, true);
return $data['rates'][$to_currency] ?? false;
}
return false;
}
$exchangeRate = 55; // Default exchange rate (e.g., USD to PHP)
if (isset($_POST['convert'])) {
$amount = floatval($_POST['amount']);
$type = $_POST['type']; // 'buy' or 'sell'
// Optionally fetch live exchange rate
$liveRate = getExchangeRate('USD', 'PHP');
if ($liveRate) {
$exchangeRate = $liveRate;
}
if ($type === 'buy') {
$total = $amount * $exchangeRate;
} else {
$total = $amount * ($exchangeRate - 0.5); // Slightly lower for selling
}
$message = "Converted Amount: " . number_format($total, 2) . " PHP";
}
?>

<h2>Dollar Exchange System</h2>
<form method="POST">
<label>Amount (USD):</label>
<input type="number" step="0.01" name="amount" required>
<label>Type:</label>
<select name="type">
<option value="buy">Buy</option>
<option value="sell">Sell</option>
</select>
<button type="submit" name="convert">Convert</button>
</form>
<?php if (isset($message)) : ?>
<h3><?php echo $message; ?></h3>
<?php endif; ?>
</body>
</html>
đ§ How It Works:
- The user enters an amount in USD.
- Selects Buy (USD to PHP) or Sell (PHP to USD).
- The script calculates the total based on a fixed or live exchange rate.
- Displays the converted amount.
đ Next Steps (Optional Enhancements)
- Use a database to store exchange rates.
- Allow admin to set custom rates.
- Implement an authentication system.
Would you like me to integrate this with a database or add more features? đ
