How do I write a function that can accept unlimited number of parameters?
What am trying to do is create a function within a class that wraps the following:
$stmt->bind_param('sssd', $code, $language, $official, $percent);
php
arguments

You can use either:
example($argument1, '', 'test');
Or
example($argument1, NULL, 'test');
You can always check for NULL using instead of empty string:
if ($argument === NULL) {
//
}
I think it all depends on what happens inside the function with the args.

You can try something like this:
//routes.php
Route::get('{pageLink}/{otherLinks?}', 'SiteController@getPage')->where('otherLinks', '(.*)');
Remember to put the above on the very end (bottom) of routes.php file as it is like a 'catch all' route, so you have to have all the 'more specific' routes defined first.
//controller
class SiteController extends BaseController {
public function getPage($pageLink, $otherLinks = null)
{
if($otherLinks)
{
$otherLinks = explode('/', $otherLinks);
//do stuff
}
}
}
This approach should let you use unlimited amount of params, so this is what you seem to need.

In PHP, use the function func_get_args to get all passed arguments.
<?php
function myfunc(){
$args = func_get_args();
foreach ($args as $arg)
echo $arg."/n";
}
myfunc('hello', 'world', '.');
?>
An alternative is to pass an array of variables to your function, so you don't have to work with things like $arg[2]; and instead can use $args['myvar']; or rewmember what order things are passed in. It is also infinitely expandable which means you can add new variables later without having to change what you've already coded.
<?php
function myfunc($args){
while(list($var, $value)=each($args))
echo $var.' '.$value."/n";
}
myfunc(array('first'=>'hello', 'second'=>'world', '.'));
?>

Use debug_backtrace instead. It will give you the whole trace and doesn't trim arguments as far as I know.
On a second thought: You might get away with it by using
try {
...
} catch (Exception $e)
var_dump($e->getTrace());
}
instead.

The above suggests are all good, but I don't think they will be suitable for your situation.
If you want to wrap this function, you will need to pass references to the original argument variables to the bind_param function. I don't think func_get_args() gives you this, it gives you values instead. Thus it won't be possible to use these to pass to the parent function. I battled with a similar issue when trying to extend mysqli_stmt and never came to satisfactory solution.
This is not really an answer to your question I'm afraid, just a warning that other arguments may not work in your particular application of arbitrary number of arguments.
