What is the recommended method for accessing variables sent via a POST request in PHP?

When receiving variables sent via a POST request in PHP, the recommended method is to use the $_POST superglobal array. This array contains key-value pairs of all the variables sent via the POST request. To access a specific variable, you can use $_POST['variable_name'] where 'variable_name' is the name of the variable sent in the POST request. 

// Accessing a variable sent via POST request
if(isset($_POST['variable_name'])){
    $variable_value = $_POST['variable_name'];
    // Use $variable_value for further processing
}
