What is the correct syntax for accessing variables in $_POST in PHP?

When accessing variables in $_POST in PHP, you need to use the associative array syntax with the variable name as the key. This allows you to retrieve data sent to the server using the POST method from a form. To access a specific variable, you need to specify the key corresponding to the input field name in the form.

// Accessing a variable in $_POST
$variable = $_POST['input_name'];
