Forward undefined number of arguments to another function

Question

I will explain the question with a simple function accepting any number of function

function abc() {
   $args = func_get_args();
   //Now lets use the first parameter in something...... In this case a simple echo
   echo $args[0];
   //Lets remove this first parameter 
   unset($args[0]); 

   //Now I want to send the remaining arguments to different function, in the same way as it received
   .. . ...... BUT NO IDEA HOW TO . ..................

   //tried doing something like this, for a work around
   $newargs = implode(",", $args); 
   //Call Another Function
   anotherFUnction($newargs); //This function is however a constructor function of a class
   // ^ This is regarded as one arguments, not mutliple arguments....

}

I hope the question is clear now, what is the work around for this situation?

Update

I forgot to mention that the next function I am calling is a constructor class of another class. Something like

$newclass = new class($newarguments);

Sending the remaining arguments as an array is not an acceptable solution. I want to send the argument as the same way as "arg[1], arg[2].. so on and so forth... — Starx

for simple function calls

use call_user_func_array, but do not implode the args, just pass the array of remaining args to call_user_func_array

call_user_func_array('anotherFunction', $args);

for object creation

use: ReflectionClass::newInstanceArgs

$refClass = new ReflectionClass('yourClassName');
$obj = $refClass->newInstanceArgs($yourConstructorArgs);

or: ReflectionClass::newinstance

$refClass = new ReflectionClass('yourClassName');
$obj = call_user_func_array(array($refClass, 'newInstance'), $yourConstructorArgs);

What if the next function is a constructor of a class?

@Starx See the added example.

For the object creation, which one is preferred solution, first one or the second

Yoshi Over a year ago

@Starx I'd go for the first one.
