我试图使用php解析包含我商店产品的json文件，但是没有运气！我是php的新手，我尝试过在线搜索，但没有答案。这是我的json文件的一部分：
[
{
"_type": "default",
"description": [
"Product Description comes here"
],
"url": "here is the url to my seo friendly url",
"price": [
"11.64"
],
"sizes": [
"sizes come here"
],
"images": [
"image name and address is here"
],
"_template": "5c1333451e128f546e451197f6c6061b3a66d1ee",
"_cached_page_id": "5119b553b1512ae1a19d6cd0d3f29e51e111a90c",
"name": [
"product name is here"
]
},
{
"_type": "default",
"description": [
"Product #2 Description comes here"
],
"url": "here is the url to my seo friendly url",
"price": [
"11.64"
],
"sizes": [
"sizes come here"
],
"images": [
"image name and address is here"
],
"_template": "5c1333451e128f546e451197f6c6061b3a66d1ee",
"_cached_page_id": "5119b553b1512ae1a19d6cd0d3f29e51e111a90c",
"name": [
"product #2 name is here"
]
}
]
这只是整个json文件的示例，但它遵循这种格式。我尝试编写以下php代码对其进行索引，但正如我所说，没有运气：
<?php
// this code reads from the files provided to it and populates the database with products
$jsondata = file_get_contents("55products.json");
$json = json_decode($jsondata, true);
foreach ($json["products"] as $product)
{
// now lets split it into smaller pieces
foreach ($product as $product_infos) {
print_r($product_infos);
echo "<br /><br /><br />";
}
}
但是仍然无法访问内容或具体来说，我不知道如何访问其中的数据存储。我知道这可能是一个非常愚蠢的问题，但是所有在线教程都没有类似的语法，因此请帮助我。最好的祝福。
内部元素本身就是数组，您需要使用索引0访问值
$obj = json_decode($json,true);
// var_dump($obj);exit;
foreach ($obj as $product)
{
print $product["description"][0] . "<br/>";
print $product["images"][0] . "<br/>";
print $product["url"] . "<br/>";
print $product["name"][0] . "<br/>";
}
将输出
Product Description comes here
image name and address is here
here is the url to my seo friendly url
product name is here
Product #2 Description comes here
image name and address is here
here is the url to my seo friendly url
product #2 name is here
