Optional Arguments Pass By Reference

[donoe]

hi guys,

what i'm trying to do is to do a function addslashes to all my arguments.. before putting them into the db.

im trying to achieve something like

all_adddslashes($arg1,$arg2,$arg3)

but i realised that this has to be done thru passing reference. any ideas how to handle optional arguments by reference?

e.g:

function all_addslashes() {
$numargs = func_num_args();
$arg_list = func_get_args();
for ($i = 0; $i < $numargs; $i++) {
addslashes($arg_list[$i]);
}
}

any help would be appreciated!! thanks!

I'm not entirely sure there is one, not without some hairy-looking stuff at least. Personally I find the idea a bit creepy, but side-effects do that to me.
I'd prefer to just bundle them into an array and

$arrayofarguments = array_map('addslashes', $arrayofarguments);

If need be the first $arrayofarguments could be replaced by a list() and the second by an array().

Cool idea. I had to try it out just to prove to myself it would work:

$str1 = "This here's a test.";
$str2 = 'This is \a test\.';
$str3 = "No slashes needed here.";
list($str1,$str2,$str3) = array_map('addslashes', array($str1,$str2,$str3));
echo "<pre>$str1\n$str2\n$str3</pre>\n";

Output:

This here\'s a test.
This is \\a test\\.
No slashes needed here.
