jsonからkey mtachedの値を取得する方法

Question

私はflipkart new product apiで作業していますが、実際には配列の位置を使用してapiからすべての値を得ましたが、キー値がtrueの場合は値を取得します。ここ

は参照 http://myperfectprice.com/flipkart.json

のデモで、ここに私のコード

<?php 
$url='http://myperfectprice.com/flipkart.json'; 
$decode=file_get_contents($url);   
$product = json_decode($decode,true); 
$keySpecs = $product['categorySpecificInfoV1']['keySpecs'][0]; 
$Brand = $product['categorySpecificInfoV1']['specificationList'][0] ['values'][1]['value'][0]; 
$model = $product['categorySpecificInfoV1']['specificationList'][0]['values'][2]['value'][0]; 
$sim_size = $product['categorySpecificInfoV1']['specificationList'][0]['values'][3]['value'][0]; 
$sim_type = $product['categorySpecificInfoV1']['specificationList'][0]['values'][4]['value'][0]; 

?> 
keySpecs=<?=$keySpecs; ?><br /> 
Brand=<?=$Brand; ?><br /> 
Model=<?=$model; ?><br /> 
Sim_size=<?=$sim_size; ?><br /> 

Answer 1

使用in_array()あなたの配列の"GENERAL FEATURES"を見つけて、存在する場合は、別の配列にspecificationListを割り当てる...

<?php 
$url='http://myperfectprice.com/flipkart.json'; 
$decode=file_get_contents($url);   
$product = json_decode($decode,true); 
if(in_array('GENERAL FEATURES',$product['categorySpecificInfoV1']['specificationList'][0])) 
{ 
    $specificationList = $product['categorySpecificInfoV1']['specificationList']; 
} 
echo "<pre>"; print_r($specificationList); 
?> 

Answer 2

である私は多分このような何かが動作する、非常によく質問を理解していませんか？

if ($product['categorySpecificInfoV1']['specificationList']['key'] == 'GENERAL FEATURES'){ 
    //get the specificationList 
}
