What are the workarounds for handling variable parameters in PHP functions?

When dealing with variable parameters in PHP functions, one common workaround is to use the func_get_args() function to retrieve all passed arguments as an array. Another approach is to use the func_num_args() function to determine the number of arguments passed to the function. These functions allow you to create flexible functions that can handle different numbers of parameters. 

function sum() {
    $args = func_get_args();
    $total = 0;
    
    foreach ($args as $arg) {
        $total += $arg;
    }
    
    return $total;
}

echo sum(1, 2, 3, 4); // Output: 10
