我不确定我所问的是否合理,但我会尽力解释。我有一些JSON数据,我使用cURL打印出来,对象的一部分打印出来,
国内啤酒(0.5升吃水),餐厅
然后下一行将是
新鲜白面包(500克),市场
我想知道是否有可能遍历数据数组并查看哪些部分包含“餐馆”一词并将它们组合成一个变量,然后对makets执行相同操作?
到目前为止,这是我的数组代码
$json = json_decode($r);
$json->monthLastUpdate;
// search through data for printing
echo "<div id='results'>";
echo "<h2> Prices for $country </h2>";
foreach($json->prices as $prices) {
// echos out the selected items into a list
echo "</div>";
echo "<p>" . $prices->item_name . " <br><b> Average price </b>";
$pricedata ="$prices->average_price";
//rounds the numbers down to readable format
echo number_format((float)$pricedata, 2, '.', '');
echo "(";
echo $currency;
echo ")";
这是我从查询
收到的JSON数据 {
"monthLastUpdate": 3,
"contributors": 4424,
"name": "India",
"prices": [
{
"average_price": 0.984819890047,
"item_name": "Meal, Inexpensive Restaurant, Restaurants",
"highest_price": 1.96963978009,
"item_id": 1,
"lowest_price": 0.64013292853
},
{
"average_price": 4.92409945023,
"item_name": "Meal for 2, Mid-range Restaurant, Three-course, Restaurants",
"highest_price": 7.87855912037,
"item_id": 2,
"lowest_price": 3.0005
},
答案 0 :(得分:0)
如果格式是一致的并且假设项目名称中没有逗号,则可以执行以下操作:
$itemCatalog = array();
foreach($items as $item){
$chunks = explode("," $item);
$category = $chunks[1];
$itemName = $chunks[0];
$itemCatalog[$category][] = $itemName;
}
之后,您将拥有一个多维数组,其中包含按类别排序的项目。
