我正在进入一个项目，我试图从json响应中获取信息（再次），这是我从谷歌+获得的。 我需要在使用json响应中的一些信息填充数组后返回一个数组。
[修改] json响应是：

这就是我正在做的事情：
function google_pluss() {
$file_dir = strtolower(realpath(APPPATH . '..' . DIRECTORY_SEPARATOR . 'assets'));
$json_file = $file_dir . DIRECTORY_SEPARATOR . 'stackoverflow' . '.json'; // I have the file locally...
$json_data = json_decode(file_get_contents($json_file));
$data = array();
if (isset($json_data)) {
$x = 0;
foreach ($json_data->items as $item) {
if (isset($item->object->attachments)) {
foreach ($item->object->attachments as $attachment) {
$data['number'][$x] = $attachment->content;
$data['image'][$x] = $attachment->fullImage->url;
}
$data['title'][$x] = $item->title;
$x++;
}
}
}
print_r($data);
}
这是我得到的输出：
Array
(
[number] => Array
(
[0] => 123
[1] => 456
[2] => 789
)
[image] => Array
(
[0] => https://lh5.googleusercontent.com/-2dgjFRSDSDD8/VcyMSDSDSI/BAAHYGHDSJHDSIKA/0XtjIUYDIGIDGerY/11017878_1655020DSDKHSJ612_1878283374SDSDSD30482_n.jpg

)
[title] => Array
(
[0] => first title
[1] => second title
[2] => third title
)
)
但是，这是我实际需要的输出：
Array
(
[0] => Array
(
[number] => 123
[image] => https://lh5.googleusercontent.com/-2dgjFRSDSDD8/VcyMSDSDSI/BAAHYGHDSJHDSIKA/0XtjIUYDIGIDGerY/11017878_1655020DSDKHSJ612_1878283374SDSDSD30482_n.jpg

[title] => second title
)
[2] => Array
(
[number] => 789
[image] => https://lh3.googleusercontent.com/-uihfjbsdhgsdilop/VcvPJmJ0bUI/wERRDFFAAAAN8/XyghFGF2TgBak/w562-h562/PicsArt_1438914428134.jpg
[title] => third title
)
)
如果有人告诉我如何实现这一点，我真的很感激，谢谢。
顺便说一句，我使用$x变量并递增它，以停止数组不包含attachments的循环。我也很高兴，如果看到如何做这个整洁。
答案 0 :(得分：1)
乍一看，我会说改变
foreach ($item->object->attachments as $attachment) {
$data['number'][$x] = $attachment->content;
$data['image'][$x] = $attachment->fullImage->url;
}
到
foreach ($item->object->attachments as $attachment) {
$data[$x]['number'] = $attachment->content;
$data[$x]['image'] = $attachment->fullImage->url;
}
