php循环列表中的随机产品[关闭]

我有来自女巫的产品列表，我需要随机显示四个项目。

<?php 

// my product list
function productlistX {
    $array = array( 

        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};
        $product {$name = 'product name', $link = 'product link', $img = "product image"};

    )

    // need to display 4 random products from the array above 
    foreach  {
        echo "<li>".$name . $link . $img . "</li>"
    }
}

// display these random products in my ajax tab (products.php?order=mytab)
$data['mytab'] = $productlistX;

if (isset($data[$_GET['order']])) { 
    echo $data[$_GET['order']];
} 
?>

正如您所看到的，我有一个列表，只需随机显示列表中的四个项目。

提前致谢！

这可以通过 php 来完成rand() http://php.net/manual/en/function.rand.php函数或者您也可以使用数组随机数 http://php.net/manual/en/function.array-rand.php要首先使用数组 rand，您需要创建数组
