我解码了一个包含PHP中的键和值的JSON数组。 JSON看起来像(缩短以便于理解):
json_decode
在我Array ( [0] => stdClass Object ( [code] => 123 ) [1] => stdClass Object ( [identification] => Some item ) [2] => stdClass Object ( [price] => $20 ) )
之后,它看起来像这样:
foreach ($jarray as $key) {
echo 0->$key;
}
如何读取密钥和值?
我已经尝试过搜索SO了,并且已经尝试过这样的事情:
foreach ($jarray as $key => $value) {
echo $key;
echo $value;
}
会引发500(ISE)错误。
还试过这个:
code - 123
identification - Some item
price - $20
...
也会引发500错误。
我不知道如何做到这一点......
编辑:基本上,我只是希望通过整个事情进行迭代,并且每次都获得关键和值,如下所示:
var express = require('express')
var app = express();
var http = require('http').Server(app);
var path = require('path');
var port = process.env.port || 1337;
app.use(express.static(__dirname + 'client'));
app.get('/', function (req, res) {
res.sendFile(path.join(__dirname,'client', 'HTML1.html'));
});
http.listen(port, function () {
console.log(`listning on ${port}`);
})

$json = '[{"code":"123"},{"identification":"Some item"},{"price":"$20"}]';
$jarray = json_decode($json, true);
foreach ($jarray as $value) {
foreach ($value as $key => $val) {
echo $key;
echo $val;
}
}

I hope so it will reduce loop process confusion and simple to do this task.
$text = '[{"code":"123"},{"identification":"Some item"},{"price":"$20"}]';
$array = json_decode($text);**strong text**
foreach($array as $value)
{
$array = (array)$value;
$x = each($array);
echo $x['key'];
echo "====>>>>";
echo $x['value'];
echo "<br/>";
}
