json配列をPHPの価格帯にリストアップ

Question

問題が残っています。私は範囲内のjson配列要素をリストする必要があります。

$search = $_POST['search']; 
$cat_id = $_POST['category']; 
$post1 = file_get_contents("....?search=".$search."&category=".$cat_id); 
$data = CJSON::decode($post1, true); 
$products = $data['products']; 
$pricerange = $_POST['pricerange']; 
$myArray = explode('-',$pricerange); 
$a =explode('$',$myArray[0]); 
$b =explode('$',$myArray[1]); 

$a

Controllerページ........行う方法を知ってはいけないの下限であると$bが上限である、$productsがリストされなければならJSON配列であります。

$productsの価格帯を$aから `$ b 'に設定する方法を知る必要があります。 $製品

Answer 1

私はあなたのための小さなスクリプトを作成して、それはあなたがJSONを変更することができ

function sortbyprice($a, $b) { 
     return $a['retail_price'] - $b['retail_price']; 
    } 
    $result_Array = array(
     array('id'=>'11027','retail_price'=>'9.99'), 
     array('id'=>'11548','retail_price'=>'10.99'), 
     array('id'=>'11528','retail_price'=>'3.99'), 
     array('id'=>'18548','retail_price'=>'55.99') 
    ); 
echo '<pre>'; 
print_r($result_Array); 
usort($result_Array, 'sortbyprice'); 
print_r($result_Array);
