Detailed explanation of function func_get_args

function foo()
{
    $numargs = func_num_args(); //Number of arguments
    echo "The number of arguments is: $numargs<br />\n";
    if ($numargs >= 2) {
        echo "The value of the second argument:" . func_get_arg(1) . "<br />\n";
    }
    $arg_list = func_get_args();
    for ($i = 0; $i < $numargs; $i++) {
        echo "{$i}th parameter value: {$arg_list[$i]}<br />\n";
    }
}
 
foo(1, 'd', 3,4);

Output: The
number of parameters is: 4
The value of the second parameter: d The value of
the 0th parameter: 1
The value of the 1st parameter: d
