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);
}
}
?>
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. =/

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