How do you write a function for which the number of variables to be inputted into it will change each time the function is used. Functions are generally written:

function name ($variable1, $variable2, $variable3) {
do something;
}

In the above function, the variables go up to $variable3, but I want to write a function in which they go up to $variableX where X is determined each time the function is run. Can anyone tell me how to do this? Specifically I am trying to do this in php, but I dont think that matters so much. Thanks guys!

Use an array, and loop through it.

Thanks, got it working.

use func_num_args() and func_get_args():

PHP Code:

function foo()
{
   $numargs = func_num_args();
   echo "this function was passed $numargs";
   
   $arg_list = func_get_args();
   for ($i = 0; $i < $numargs; $i++) {
       echo "Argument $i is: " . $arg_list[$i] . "<br />\n";
   }
}

foo(1, 2, 3);

Cool, that one actually works even better for me. When using the other method mentioned earlier in the thread, had to manually set the variables for the array, which meant that I would have had to do that each time I called the function. This method looks like I can skip that step.
