Is it possible to grab a variable number of parameters and send the appropriate amount to another function?

You can predefine function parameters: <?php function example($line1,$line2="There is no line 2.") { echo $line1."\n"; echo $line2."\n"; } example("This is a test.","This is another test."); /* Returns:

      This is a test.
      This is another test.

*/ example("This is a third test."); /* Returns:

      This is a third test.
      There is no line 2.

*/ ?> .... but more likely, you're looking for func_get_args().

      http://php.net/func_get_args

Fortunately, I am quite familiar with your example. However, I am more looking for something in which I could send any number of parameters to my own function, grab each one of those individually, and then send them each to another built-in function. Basically, I want to avoid hard-coding this. On top of looking ugly, it's bad practice. <?php function myFunction () { $args = func_get_args(); anotherFunction ($args[0], $args[1], $args[2], $args[3], $args[4], $args[5]); // And continue counting up to a random number where I don't // think I'll have more than, say, 10 arguments } ?> Of course, even if I did hard-code this nastiness, anotherFunction() would still complain about whatever parameters were not used. So, args 0 and 1 are filled, but 2-5 are not. "Warning! Warning! You can't have args 2 through 5, stoopud!" Alas, I feel I must take a different approach to solve this problem. ~Philip

Hi Phillip Why not use a foreach()? <?php function myFunction () { $args = func_get_args(); foreach($args as $arg) anotherFunction ($arg); } } ?>

This isn't exactly what I'm wanting to achieve. I don't want to send each parameter individually, I want to send them all at the same time. It's *almost* like I want to create a string of parameters that I can send...... <?php function myFunction () { $args = func_get_args(); foreach ($args as $arg) {

    $sendThis .= $arg . ', ';

} anotherFunction (rtrim ($sendThis, ', ')); } myFunction (1, 5, 'Hi'); // This will result in calling anotherFunction as such anotherFunction ('1, 5, Hi'); // and not anotherFunction (1, 5, 'Hi'); ?> But, of course, this won't work because now 'sendThis' is a single string - not what I want. Thanks for the thoughts anyhow. =/ ~Philip

That way you can send as many arguments as you please, without any ugly hardcoding... Igor
