我有一个具有以下结构的json文件：
[{
"Item": {
"name": "Item 1",
"schedule": {
"class": "Class",
"uic": "UIC"
},
"days": "Mondays",
"segment": {
"branding": "A1",
"location": [{
"location_type": "L1",
"time": "18:00"
}, {
"location_type": "L2",
"time": "18:15"
}, {
"location_type": "L3",
"time": "18:18"
}]
},
"transaction": "Trans"
}
}, { "Item": {
"name": "Item 2",
"schedule": {
"class": "Class",
"uic": "UIC"
},
"days": "Tuesdays",
"segment": {
"branding": "A2",
"location": [{
"location_type": "Lu1",
"time": "19:00"
}, {
"location_type": "L2",
"time": "19:15"
}, {
"location_type": "L3",
"time": "19:18"
}, {
"location_type": "L4",
"time": "19:25"
}]
},
"transaction": "Trans"
}
}]
我正在使用 php 的 json 解码来输出这些数据，但我不确定如何实现我想要的。我试图将此数据作为每个项目的每个 location_type 值的新行输出，基本上列出每个项目的每个组合。
下面的示例本质上是我想要输出的内容：
Item 1, Class, UIC, Mondays, A1, L1, 18:00, Trans
Item 1, Class, UIC, Mondays, A1, L2, 18:15, Trans
Item 1, Class, UIC, Mondays, A1, L3, 18:17, Trans
Item 2, Class, UIC, Tuesdays, A2, L1, 19:00, Trans
Item 2, Class, UIC, Tuesdays, A2, L2, 19:15, Trans
Item 2, Class, UIC, Tuesdays, A2, L3, 19:17, Trans
Item 2, Class, UIC, Tuesdays, A2, L4, 19:25, Trans
我假设我需要深入到该位置，然后循环遍历每个项目，但我的 php 有限，我找不到任何似乎可以实现此目的的东西。
谢谢。
如果您的 JSON 正确（但事实并非如此），代码将如下所示：
foreach($JSON as $item)
{
$item = $item->Item; // because you changed the code
for($i=0;$i<count($item->segment->location);$i++)
{
echo $item->name, ', ';
echo $item->schedule->class. ', ';
echo $item->schedule->uic. ', ';
echo $item->days. ', ';
echo $item->segment->branding. ', ';
echo $item->segment->location[$i]->location_type. ', ';
echo $item->segment->location[$i]->time. ', ';
echo $item->segment->transaction. '<br>';
}
}
假设你的 json 位于变量 $json
$array = json_decode($json);
foreach ($array as $value) {
foreach ($value->Item->segment->location as $loc) {
echo sprintf('%s, %s, %s, %s, %s, %s, %s, %s <br>',
$value->Item->name,
$value->Item->schedule->class,
$value->Item->schedule->uic,
$value->Item->days,
$value->Item->segment->branding,
$loc->location_type,
$loc->time,
$value->Item->transaction
);
}
}
这将输出
Item 1, Class, UIC, Mondays, A1, L1, 18:00, Trans
Item 1, Class, UIC, Mondays, A1, L2, 18:15, Trans
Item 1, Class, UIC, Mondays, A1, L3, 18:18, Trans
Item 2, Class, UIC, Tuesdays, A2, Lu1, 19:00, Trans
Item 2, Class, UIC, Tuesdays, A2, L2, 19:15, Trans
Item 2, Class, UIC, Tuesdays, A2, L3, 19:18, Trans
Item 2, Class, UIC, Tuesdays, A2, L4, 19:25, Trans

将 JSON 数据添加到 $json 变量中。如果您有任何其他疑问，请查看此示例
<?php $data = json_decode($json, true);
foreach ($data as $entry) {
$item = $entry['Item'];
$name = $item['name'];
$class = $item['schedule']['class'];
$uic = $item['schedule']['uic'];
$days = $item['days'];
$branding = $item['segment']['branding'];
$transaction = $item['transaction'];
foreach ($item['segment']['location'] as $location) {
$locationType = $location['location_type'];
$time = $location['time'];
echo "$name, $class, $uic, $days, $branding, $locationType, $time, $transaction<br>";
}
}
?>
