我试图了解如何从json结果中获取SKU(以及另外的ID)。当只有一组名为SKU的值时,我可以这样做,但是当有多个值时,我花了好几个小时试图了解如何执行此操作。
以下是我的json返回的示例
{
"variants": [
{
"id": 6852445,
"name": "Ikan VK7i 7\" LCD Monitor for Sony L with sun hood",
"sku": "VK7i-S-SHX7",
},
{
"id": 6852388,
"name": "ikan Flyweight DSLR",
"sku": "ELE-FLWDSLR",
},
{
"id": 6838367,
"name": "Atomos Sun Hood for Ninja/Ninja-2 including Double Adapter",
"sku": "AO-ATOMSUN001",
},
]
}

我目前有这个代码(我是新手)。我想要做的是使sku和ID都变量,但我只是碰到了一堵砖墙。目前我得到
警告:在第15行的/home/pearingc/public_html/returns/test2.php中为foreach()提供的参数无效
<?php
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Bearer *my token details* ")
)
);
$url = "http://api.tradegecko.com/variants/";
$data = file_get_contents($url, false, $context);
$json = json_decode($data, true);
$product = $json{'variant'}->{'sku'};
foreach ($product['sku'] as $sku) {
print $sku;
}
?>

编辑:这就是var_dump($ json);给我

我认为你的JSON格式不正确。注意:我在sku
之后删除了逗号。试试这个:
$data = '{
"variants": [
{
"id": 6852445,
"name": "Ikan VK7i 7\" LCD Monitor for Sony L with sun hood",
"sku": "VK7i-S-SHX7"
},
{
"id": 6852388,
"name": "ikan Flyweight DSLR",
"sku": "ELE-FLWDSLR"
},
{
"id": 6838367,
"name": "Atomos Sun Hood for Ninja/Ninja-2 including Double Adapter",
"sku": "AO-ATOMSUN001"
}
]
}';
之后:
$json = json_decode($data);
foreach ($json->variants as $row) {
print $row->sku;
}

<?php
$json = '{

"name": "Ikan VK7i 7\" LCD Monitor for Sony L with sun hood",

},
{
"id": 6838367,
"name": "Atomos Sun Hood for Ninja/Ninja-2 including Double Adapter",
"sku": "AO-ATOMSUN001"
}
]
}';
foreach(json_decode($json,true)['variants'] as $item) {
echo $item['sku'] . "<br />";
}
?>
凝聚了一点。
