Sure, I can help you with that.
To send the radio button value in PHP using JavaScript, you can use the 
onchange event. The onchange event is triggered when the value of an element changes.
The following code shows how to send the radio button value in PHP using JavaScript:
JavaScript
// Get the radio button value.
var radioButtonValue = document.querySelector("input[name='my_radio_button']").value;
// Send the radio button value to PHP.
var xhr = new XMLHttpRequest();
xhr.open("POST", "/my_php_script.php");
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.send("radio_button_value=" + radioButtonValue);
In this code, the radioButtonValue variable is the value of the radio button that is selected. The
xhr variable is an XMLHttpRequest object that is used to send the radio button value to PHP. The
send() method of the xhr object is used to send the radio button value to PHP.
The my_php_script.php file can be used to process the radio button value. The following code shows a simple
my_php_script.php file:
PHP
andlt;?php
// Get the radio button value.
$radioButtonValue = $_POST['radio_button_value'];
// Do something with the radio button value.
echo "The radio button value is " . $radioButtonValue;
?>
In this code, the $_POST['radio_button_value'] variable is used to get the radio button value that was sent from JavaScript. The
echo statement is used to print the radio button value to the browser.
