What are the potential issues with passing variables between PHP pages using radio buttons and form submission?

The potential issue with passing variables between PHP pages using radio buttons and form submission is that the selected value may not be properly captured or processed. To solve this, you can use the $_POST superglobal array to retrieve the selected value from the form submission and then use it in the subsequent PHP page. 

// HTML form with radio buttons
<form method="post" action="process.php">
    <input type="radio" name="option" value="option1"> Option 1
    <input type="radio" name="option" value="option2"> Option 2
    <input type="submit" value="Submit">
</form>

// process.php to retrieve and use the selected value
<?php
if(isset($_POST['option'])){
    $selectedOption = $_POST['option'];
    
    // Use the selected option in your PHP logic
    echo "Selected option: " . $selectedOption;
}
?>
