Php 每4个实例分解一个字符串并创建一个新数组

我有一根这样的绳子

$string = "title1|1.99|www.website.com|www.website.com/img1.jpg|title2|5.99|www.website2.com|www.website2.com/img2.jpg|title3|1.99|www.website3.com|www.website3.com/img3.jpg|";

我希望将字符串分解为一个数组，但每4个管道实例创建一个新数组。也将是很好的名称以及下面的钥匙

例如：

等等

我如何才能做到这一点？

您正在寻找数组块：

您正在查找数组\u块：

以下是一种功能性方法：

Array
(
    [0] => Array
        (
            [title] => title1
            [price] => 1.99
            [url] => www.website.com
            [gallery] => www.website.com/img1.jpg
        )

    [1] => Array
        (
            [title] => title2
            [price] => 5.99
            [url] => www.website2.com
            [gallery] => www.website2.com/img2.jpg
        )

    [2] => Array
        (
            [title] => title3
            [price] => 1.99
            [url] => www.website3.com
            [gallery] => www.website3.com/img3.jpg
        )

)

输出：

注意：我从字符串中删除了尾随的|。您需要这样做，否则explode将返回一个额外的空白字符串。

这里有一个函数方法：

Array
(
    [0] => Array
        (
            [title] => title1
            [price] => 1.99
            [url] => www.website.com
            [gallery] => www.website.com/img1.jpg
        )

    [1] => Array
        (
            [title] => title2
            [price] => 5.99
            [url] => www.website2.com
            [gallery] => www.website2.com/img2.jpg
        )

    [2] => Array
        (
            [title] => title3
            [price] => 1.99
            [url] => www.website3.com
            [gallery] => www.website3.com/img3.jpg
        )

)
