在 PHP 中为 JSON return 创建对象的 table
Make table of object in PHP for JSON return
我正在使用这个脚本来制作 json :
<?php
header('Content-Type: application/json');
$feed = new DOMDocument();
$feed->load("http://www.feedforall.com/sample.xml");
//$feed->load($_GET['url']);
$json = array();
$json['title'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('title')->item(0)->firstChild->nodeValue;
$json['description'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('description')->item(0)->firstChild->nodeValue;
$json['link'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('link')->item(0)->firstChild->nodeValue;
$items = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('item');
$json['item'] = array();
$i = 0;
foreach($items as $item) {
$title = $item->getElementsByTagName('title')->item(0)->firstChild->nodeValue;
$description = $item->getElementsByTagName('description')->item(0)->firstChild->nodeValue;
$pubDate = $item->getElementsByTagName('pubDate')->item(0)->firstChild->nodeValue;
$guid = $item->getElementsByTagName('guid')->item(0)->firstChild->nodeValue;
$json['item'][$i++]['title'] = $title;
$json['item'][$i++]['description'] = $description;
$json['item'][$i++]['pubdate'] = $pubDate;
$json['item'][$i++]['guid'] = $guid;
}
echo json_encode($json);
?>
在 foreach 循环中，它把 feed 的所有项目一个接一个地放入项目 php table.
当我return时，没有table，所有物品属性都平发：

您每 属性 增加一次计数器。由于它设置为 0 开始，所以你应该只在最后这样做：
$json['item'][$i++]['title'] = $title;
$json['item'][$i++]['description'] = $description;
$json['item'][$i++]['pubdate'] = $pubDate;
$json['item'][$i++]['guid'] = $guid;
应该是：
$json['item'][$i]['title'] = $title;
$json['item'][$i]['description'] = $description;
$json['item'][$i]['pubdate'] = $pubDate;
$json['item'][$i]['guid'] = $guid;
# Increment the counter for the next iteration
$i++;
您每次添加新项目时都会递增 $i。试试这个：
$json['item'][$i++] = array(
'title' => $title,
'description' => $description,
'pubdate' => $pubDate,
'guid' => $guid,
);
或者：
$json['item'][$i]['title'] = $title;
$json['item'][$i]['description'] = $description;
$json['item'][$i]['pubdate'] = $pubDate;
$json['item'][$i]['guid'] = $guid;
$i++;
我正在使用这个脚本来制作 json :
<?php
header('Content-Type: application/json');
$feed = new DOMDocument();
$feed->load("http://www.feedforall.com/sample.xml");
//$feed->load($_GET['url']);
$json = array();
$json['title'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('title')->item(0)->firstChild->nodeValue;
$json['description'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('description')->item(0)->firstChild->nodeValue;
$json['link'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('link')->item(0)->firstChild->nodeValue;
$items = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('item');
$json['item'] = array();
$i = 0;
foreach($items as $item) {
$title = $item->getElementsByTagName('title')->item(0)->firstChild->nodeValue;
$description = $item->getElementsByTagName('description')->item(0)->firstChild->nodeValue;
$pubDate = $item->getElementsByTagName('pubDate')->item(0)->firstChild->nodeValue;
$guid = $item->getElementsByTagName('guid')->item(0)->firstChild->nodeValue;
$json['item'][$i++]['title'] = $title;
$json['item'][$i++]['description'] = $description;
$json['item'][$i++]['pubdate'] = $pubDate;
$json['item'][$i++]['guid'] = $guid;
}
echo json_encode($json);
?>
在 foreach 循环中，它把 feed 的所有项目一个接一个地放入项目 php table.
当我return时，没有table，所有物品属性都平发：

您每 属性 增加一次计数器。由于它设置为 0 开始，所以你应该只在最后这样做：
$json['item'][$i++]['title'] = $title;
$json['item'][$i++]['description'] = $description;
$json['item'][$i++]['pubdate'] = $pubDate;
$json['item'][$i++]['guid'] = $guid;
应该是：
$json['item'][$i]['title'] = $title;
$json['item'][$i]['description'] = $description;
$json['item'][$i]['pubdate'] = $pubDate;
$json['item'][$i]['guid'] = $guid;
# Increment the counter for the next iteration
$i++;
您每次添加新项目时都会递增 $i。试试这个：
$json['item'][$i++] = array(
'title' => $title,
'description' => $description,
'pubdate' => $pubDate,
'guid' => $guid,
);
或者：
$json['item'][$i]['title'] = $title;
$json['item'][$i]['description'] = $description;
$json['item'][$i]['pubdate'] = $pubDate;
$json['item'][$i]['guid'] = $guid;
$i++;
