Foreach remove duplicate images

Question

I have code below that pulls the images of the products of the shopping cart of the Gento, but it is displaying duplicate, IE, when it lists the images it displays twice the same image.

<?php 
    $items = Mage::getSingleton('checkout/session')->getQuote()->getAllItems() ;  

        foreach($items as $item) {                                   
            echo '<img style="width: 75px; height: 75px;" src="'.$this->helper('catalog/image')->init($item->getProduct(), 'small_image').'"/>';

        }

?>

I’d like to show off just once, end this loop.

Answer 1

array_unique($array)

<?php 
    $items = Mage::getSingleton('checkout/session')->getQuote()->getAllItems() ;  

    $items = array_unique($items);

        foreach($items as $item) {                                   
            echo '<img style="width: 75px; height: 75px;" src="'.$this->helper('catalog/image')->init($item->getProduct(), 'small_image').'"/>';

        }

?>
