Here’s the code for converting meters to feet using PHP with HTML.

<h1>Meters to Feet Converter</h1>

<label for="meters">Enter value in meters:</label>
<input type="number" name="meters" id="meters" required>
<br>
<button type="submit">Convert</button>
</form>
<?php
// Conversion factor
$conversion_rate = 3.28084;
// Check if form is submitted
if (isset($_POST['meters'])) {
$meters = (float) $_POST['meters'];
$converted_feet = $meters * $conversion_rate;
}
?>
<?php if (isset($_POST['meters'])): ?>
<p><b><?php echo $_POST['meters']; ?> meters is equal to <?php echo $converted_feet; ?> feet.</b></p>
<?php endif; ?>

Explanation:
1. Defines the basic structure with a heading, form, and result display area.
2. Uses a form to submit the value entered for meters.
3. Checks if `$_POST[‘meters’]` is set in the PHP code to display the result only after conversion.
4. Defines the conversion rate (1 meter equals 3.28084 feet).
5. Checks if the form is submitted using `isset($_POST[‘meters’])`.
6. Retrieves the entered value and converts it to feet using the conversion rate.
7. 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.
