What steps can be taken to troubleshoot issues with passing multiple variables in an AJAX request in PHP?

When passing multiple variables in an AJAX request in PHP, ensure that the data is properly formatted as key-value pairs in the AJAX request. Use the `data` parameter in the AJAX call to send an object with the variables as properties. In the PHP file, access the variables using `$_POST` or `$_GET` superglobals based on the method used in the AJAX request. 

// AJAX request
$.ajax({
    url: 'your_php_file.php',
    method: 'POST',
    data: {
        variable1: value1,
        variable2: value2
    },
    success: function(response) {
        // Handle the response
    }
});

// PHP file (your_php_file.php)
$variable1 = $_POST['variable1'];
$variable2 = $_POST['variable2'];

// Use $variable1 and $variable2 as needed
