Is it possible to grab a variable number of parameters and send the

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.

Hi Phillip
Why not use a foreach()?
<?php
function myFunction () {
$args = func_get_args();
foreach($args as $arg)
anotherFunction ($arg);
}
}
?>
That way you can send as many arguments as you please, without any ugly
hardcoding...
