Hello Friends Today, through this tutorial, I will tell you How can i Convert From Feet to Centimeters Using PHP Script Code With HTML.
Here’s the HTML and PHP code for a Feet to cm converter:
feettocm.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Feet to Centimeters Converter</title>
</head>
<body>
<h1>Feet to Centimeters Converter</h1>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
<label for="feet">Enter value in feet:</label>
<input type="number" name="feet" id="feet" required>
<br>
<button type="submit">Convert</button>
</form>
<?php
// Conversion factor
$conversion_rate = 30.48;
// Check if form is submitted
if (isset($_POST['feet'])) {
$feet = (float) $_POST['feet'];
$converted_cm = $feet * $conversion_rate;
}
?>
<?php if (isset($_POST['feet'])): ?>
<p><b><?php echo $_POST['feet']; ?> feet is equal to <?php echo $converted_cm; ?> centimeters.</b></p>
<?php endif; ?>
</body>
</html>
Explanation:
HTML
1. Defines the basic structure with heading, form, and result display area.
2. Uses a form to submit the value entered for feet.
3. Checks if `$_POST[‘feet’]` is set in the PHP code to display the result only after conversion.
PHP
1. Defines the conversion rate (1 foot equals 30.48 centimeters).
2. Checks if the form is submitted using `isset($_POST[‘feet’])`.
3. Retrieves the entered value and converts it to centimeters.
4. Displays the converted value using string interpolation within the HTML code.
This code utilizes a simple form with PHP to perform the conversion and display the result within the HTML page.
