note 86301 added to control-structures.foreach

I need help with my foreach loop

How do I return the value of the entire array? I used a foreach loop like this one:

<?php function Helpme()
	{
		global $hola;
		$invoice = $_SESSION['invoice'];
		$cart = $_SESSION['carrito'];	 
		$invoice->cart = $cart;
		$_SESSION['invoice'] = $invoice;
		
		foreach ($invoice->cart->items as $id=>$item ) 
		{
			$target = array($id," ");
			//print $target[0];
			$hola = implode("",$target);
			
			echo gettype($hola);
			//return $hola;
		} 
		
	}
	Helpme();
?>
I don't get the values of the array "$id"
