Greetings list.
Say I have a function that escapes a string before being passed to MySQL
like so:
function escape($id, &$string)
{
$string = mysql_real_escape_string($string, $id);
}
I'm passing $string as a reference so I don't have to reassign it like so:
$foo = escape($id, $foo);
Simply calling
escape($id, $foo);
works just fine.
How can I do this if I have a variable number of arguments? I know I
can use func_get_args(), func_num_args() and so forth to get the
arguments but can I still pass by reference?
It'd be so much easier to do
escape($id, $a, $b, $c, $d);
Than
$a = escape($id, a);
and so forth.
Does this make sense? Is it possible to do?
Thanks in advance,
Jay
What about something like (untested):
list($id, $a, $b, $c, $d) = escape($id, $a, $b, $c, $d);
And then instead of altering the actual values in your function by using
pass-by-reference, you can just return an array of elements instead.

Yeah, I had considered doing it that way as well. I just wanted to
remove the need to type each variable twice. It gets to be a pain when
you have longer variable names.
Thanks for the suggestion.
