How to implement a function that can take arbitrary parameters in PHP?

Question

Does PHP have such a function?

Answer 1

You can use the following functions:

• func_get_arg http://php.net/manual/en/function.func-get-arg.php
• func_get_args " http://php.net/manual/en/function.func-get-args.php
• fung_num_args " http://php.net/manual/en/function.func-num-args.php

Example:   

function my_sum() { // <--- No parameters! :D
    $total = func_num_args();
    $numbers = func_get_args();

    if ($total < 1) {
        trigger_error('Less than one number :(');
        return 0;
    } else {
        // Calculate the sum
        $sum = array_sum($numbers);
        return ($sum / $total);
    }
}

// Usage:
echo my_sum(1, 2, 5, 109, 10231);
?>
