Hello, I'm trying to implement a few simple wrappers for some PHP
functions.
Here's an example of what I'm trying to do:
function myWrapper() {
return defaultPhpFunction(func_get_args());
}
The example above is broken since I'm just passing an array to the original
function.
The only way to achieve the desired result that I've found is something
like
this:
function myWrapper() {
$argsNumber = func_num_args();
if ($argsNumber == 1) {
return defaultPhpFunction(func_get_arg(0));
}
elseif ($argsNumber == 2) {
return defaultPhpFunction(func_get_arg(0), func_get_arg(1));
}
// ...
// ...
// ...
}
Since the above code is clumsy to say the least any advice would be
welcome.
Thanks for your time!

Thank you very much for your suggestion.
I've looked into it but I guess this doesn't work with what I'm trying to
do, although what you suggested should indeed work perfectly with my
previous example.
Here's a snippet from the code that I'm having problems with:
class MainDatabase {
private static $mainDatabase = NULL;
private static $statement = NULL;
//...
//...
//...
public static function prepare($query) {
self::$mainDatabase-beginTransaction();
self::$statement = self::$mainDatabase-prepare($query);
}
public static function bindParam() {
self::$statement-call_user_func_array(array('PDOStatement','bindParam'),func_get_args());
// Results in:
// PHP Fatal error: Call to undefined method
PDOStatement::call_user_func_array() ...
// I've also tried with
call_user_func_array('PDOStatement::fetchAll',func_get_args());
// but no luck, same error.
}
//...
//...
//...
}
I thought that a solution for the previous example would work in this
scenario too, but I guess this isn't the case.
Any further suggestions would be very welcome, thanks.
Re: [PHP] Passing arguments as they are received to another function
On the line where you have
self::$statement-call_user_func_array(array('PDOStatement','bindParam'),func_get_args());
try this
call_user_func_array(array(self::$statement,'bindParam'),func_get_args());
see if that works...?

Thanks, this is working fine. I only had to make the following adjustment:
$args = func_get_args();
call_user_func_array(array(self::$statement,'bindParam'),$args);
since func_get_args as an argument is allowed only on user defined
functions.
Thank you very much for your time!
