列表中的php循环随机产品 [英] php loop random product from the list

问题描述

我有产品清单，从女巫那里我需要随机显示四个项目.

i have product list, from witch i need to display four items randomly.

<?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']];
} 
?>

因此，如您所见，我有列表蚂蚁需要只随机显示列表中的四个项目.

so as you see, i have list ant need to display only four items form the list randomly.

提前谢谢！

推荐答案

这可以通过php array_rand 首先要使用数组rand，您需要创建数组

this can be done by php rand() function or you can also use the array_rand to use the array rand first you need to create the array
