我有一个数组,如下所示:
Array
(
[count] => 2
[results] => Array
(
[0] => Array
(
[title] => My Title 1
[description] => My amazing description
[Images] => Array
(
[0] => Array
(
[pic_url] => https://my.pic.url/01/pic01-001.jpg
)
)
)
[1] => Array
(
[title] => My Title 2
[description] => Yet another amazing description
[Images] => Array
(
[0] => Array
(
[pic_url] => https://my.pic.url/02/pic02-001.jpg
)
[1] => Array
(
[pic_url] => https://my.pic.url/02/pic02-002.jpg
)
)
)
)
)
阵列中可能有1个项目或100个产品,每个产品可能具有1-5个[Images]
。我如何循环浏览它们中的每一个,以便最终获得类似于的内容
Title:
My Title 2
Description:
Yet another amazing description
Images:
https://my.pic.url/02/pic02-001.jpg
https://my.pic.url/02/pic02-002.jpg
例如,我可以用$decoded['results']['0']['title']
获得标题,但我不知道如何显示每个标题以及每个标题的未知(1到5)数量的图像URL。
您可以在此处轻松使用foreach
。此外,请确保您从迭代result
密钥(如$arr['result']
)开始。如果这个代码将被放在前端,你可以做这样的事情:
$arr = array( /* your array content */ );
foreach ($arr['results'] as $result) {
?>
<div>
<div>Title:<?= $result['title'] ?></div>
<div>Description:<?= $result['description'] ?></div>
<div>
Images:
<?php foreach ($result['Images'] as $image) { ?>
<div><?= $image['pic_url'] ?></div>
<?php } ?>
</div>
</div>
<?php
}
如果我理解你的问题,那就很容易了。循环遍历每个结果,然后在foreach中有另一个foreach,它循环遍历图像。例如
foreach($product as $prod)
{
//logic goes here
foreach($prod['images'] as $img)
{
//do stuff with image
}
}
