Are there any best practices for handling a variable number of variables in PHP methods?

When dealing with a variable number of variables in PHP methods, one common approach is to use the func_get_args() function to retrieve all passed arguments as an array. This allows for flexibility in the number of arguments passed to the method. Another approach is to use the ... operator (also known as the splat operator) in PHP 5.6+ to capture a variable number of arguments into an array. 

// Using func_get_args() to handle a variable number of variables
function exampleMethod() {
    $args = func_get_args();
    foreach ($args as $arg) {
        echo $arg . "\n";
    }
}

exampleMethod('variable1', 'variable2', 'variable3');

// Using the splat operator to handle a variable number of variables in PHP 5.6+
function exampleMethod(...$args) {
    foreach ($args as $arg) {
        echo $arg . "\n";
    }
}

exampleMethod('variable1', 'variable2', 'variable3');
