dynamic arguments in php function

arguments, dynamic, function, php

Solution

See `func_get_args`:

function foo()
{
    $numArgs = func_num_args();

    echo 'Number of arguments:' . $numArgs . "\n";

    if ($numArgs >= 2) {
        echo 'Second argument is: ' . func_get_arg(1) . "\n";
    }

    $args = func_get_args();
    foreach ($args as $index => $arg) {
        echo 'Argument' . $index . ' is ' . $arg . "\n";

        unset($args[$index]);
    }
}

foo(1, 2, 3);

EDIT 1

When you call `foo(17, 20, 31)` `func_get_args()` don't know that the first argument represents the `$first` variable for example. When you know what each numeric index represents you can do this (or similar):

function bar()
{
    list($first, $second, $third) = func_get_args();

    return $first + $second + $third;
}

echo bar(10, 21, 37); // Output: 68

If I want a specific variable, I can ommit the others one:

function bar()
{
    list($first, , $third) = func_get_args();

    return $first + $third;
} 

echo bar(10, 21, 37); // Output: 47

Problem

Possible Duplicate: PHP get all arguments as array? Well, In java I can do this (pseudocode): ``` public hello( String..args ){ value1 = args[0] value2 = args[1] ... valueN = arg[n]; } ``` and then: ``` hello('first', 'second', 'no', 'matter', 'the', 'size'); ``` Is something like this in php? EDIT I now that I can pass an array like `hello(array(bla, bla))`, but may could exists the way mencioned above, right?
