调用 url 中的数组键

Question

大家好，我在做一个项目时遇到了一些麻烦。我需要能够获取数组的键并调用 www.blach.com/1 中的键 1 并且我需要显示该键内的所有值。我将如何去做，我已经搜索了一段时间，但到目前为止，我尝试过的一切都没有奏效，我们将不胜感激。

Array(
[0] => Array
    (
        [boxId] => 917
        [contentId] => 72
        [sectionType] => hp_spl_contestants
        [contentTypeId] => 83
        [categoryId] => 0
        [countryId] => 5
        [data] => {"title":"Contestant No.1","button_txt":"Latest From","image":"2d4f8f52d49d1ab9930bc40157013a31.jpg","author":"Meenakshi Negi","url":"","date":"2012-10-04 18:16:30","badget":0,"badget_date":""}
        [insertDate] => 2012-10-05 21:05:57
        [sortorder] => 1
        [sitename] => bb6
    )

[1] => Array
    (
        [boxId] => 918
        [contentId] => 63
        [sectionType] => hp_spl_contestants
        [contentTypeId] => 83
        [categoryId] => 0
        [countryId] => 5
        [data] => {"title":"Contestant No.2","button_txt":"Latest From","image":"37154a5322838f61fb60cc24c8b5fe04.jpg","author":"Meenakshi Negi","url":"","date":"2012-10-04 18:09:06","badget":0,"badget_date":""}
        [insertDate] => 2012-10-05 21:06:16
        [sortorder] => 2
        [sitename] => bb6
    )

我试过了

$obj = json_decode($ApiData);
$Array = json_decode(json_encode($obj), true);
$data = $Array;
$id = $_GET['id'];
foreach ($data[$id] as $key=>$value){
    echo "$key -> $value<br>";
}
    ?>

但是returns出现以下错误

Invalid argument supplied for foreach()

当删除 foreach 中的 [$id] 并传入数组时 returns this

0 -> Array
1 -> Array
2 -> Array
3 -> Array
4 -> Array
5 -> Array

Answer 1

.htaccess

RewriteEngine On
RewriteBase /
RewriteRule ^(.*)$ handler.php?id=

handler.php

<?php
$data = Array();
//here you load $data with whatever you want.
$id = $_GET['id'];
foreach ($data[$id] as $key=>$value){
    echo "$key -> $value<br>";
}
?>

Answer 2

你需要使用 get 方法来调用 url，你的 url 中的 1 有一些像数字这样的值，那么你可以这样做，$url = $_GET['number'];然后您可以使用 $url 作为数组键。

调用 url 中的数组键
