PHP foreach迭代JSON數據輸出

好吧，所以我試圖把一些JSON數據輸出到PHP頁面。我的PHP代碼如下所示到目前爲止：PHP foreach迭代JSON數據輸出

從這裏輸出的顯示效果太棒了，但是飲料具有多種尺寸和價格根據大小。例如，你可以使用上面的代碼的鏈接來訪問我的JSON飼料，但這是飲料之一的一個片段，它是不同的尺寸/價格：

Year: 2015, 
Attributes: [ ], 
HasVintage: false, 
    Prices: [ 
    { 
    Size: 5, 
    Price: 2, 
    DisplayName: "Taster", 
    DisplaySize: 5.5, 
    UPCCode: null, 
    Glassware: "Nonic (Small)", 
    DisplayOnMenu: false 
    }, 
    { 
    Size: 9.5, 
    Price: 4, 
    DisplayName: "10oz", 
    DisplaySize: 10, 
    UPCCode: null, 
    Glassware: "Nonic (Small)", 
    DisplayOnMenu: true 
    }, 
    { 
    Size: 15.5, 
    Price: 6, 
    DisplayName: "16oz", 
    DisplaySize: 16, 
    UPCCode: null, 
    Glassware: "Nonic", 
    DisplayOnMenu: true 
    }, 
    { 
    Size: 35.2, 
    Price: 11, 
    DisplayName: "32oz", 
    DisplaySize: 32, 
    UPCCode: null, 
    Glassware: "Growler", 
    DisplayOnMenu: false 
    }, 
    { 
    Size: 70.4, 
    Price: 18, 
    DisplayName: "64oz", 
    DisplaySize: 64, 
    UPCCode: null, 
    Glassware: "Growler", 
    DisplayOnMenu: false 
    } 
    ], 
EventPrices: null, 
EventPricesActive: false, 
EventId: null, 
EventName: null, 
DateAdded: "2015-12-09T18:57:30.517Z", 
ProductFinished: false, 
BeverageNameWithVintage: "Eliot IPA", 
FullBeverageName: "Ex Novo Eliot IPA", 
FullProducerList: "Ex Novo", 
FullStyleName: "IPA - Hops (Galaxy, Simcoe, Centennial & Southern Cross)", 
EventItem: false, 
ReplaceableItem: false 
}, 
Active: true, 
DatePutOn: "2015-12-15T00:50:51.709Z", 
DatePulledOff: null 
},

所以我試圖做的是數字瞭解我可以如何輸出不同尺寸和價格以及我輸出的其他數據（請參閱上面的PHP代碼），並顯示各種可用的尺寸和價格，如下所示：

品酒師：$ 2 10oz：$ 4 16oz：$ 6 32oz：$ 11 64oz：$ 18

等等...

我想通了代碼，使其工作如下：

foreach($beverage['MenuItemProductDetail']['Prices'] as $price) { 
    echo '<p>'.$price['DisplayName'].': $'.$price['Price'].'</p>'; 
}

但我不能確定如何將這些代碼嵌入與下面的HTML輸出：

$percent_left_color = (max(0,min(255,511 * (1-$percent))) * 65536) + (max(0,min(255,511 * $percent)) * 256) + 40; 

    $html = 
     '<div class="keg-info">'. 
     '<div class="boxfielddata" title="'.$percent_remaining.'% remaining" >'. 

     '<div class="brewery">'.(!empty($producer_url) ? '<a href="http://'.$producer_url.'" target="_blank">' : '</a>').$producer_name.'</a> '.'</div>'. 
     '<div class="beverage-name">'.$beverage_name.'</div>'. 
     '<div class="beverage-type">'.$beverage_style.'</div>'. 
     '<div class="abv">ABV: '.$beverage_abv.'% | IBU: '.$beverage_ibu.'</div>'. 
     '<div class="reviews"> 
      <a href="'.$beer_advocate.'" target="_blank" rel="nofollow">BeerAdvocate.com</a> | <a href="'.$rate_beer.'" target="_blank" rel="nofollow">RateBeer.com</a> 
     </div>'. 
     '<div class="beverage-type">'.$displaySize.'</div>'. 
     '<span>'.($beverage_ps == '12oz' ? $beverage_ps : '').'</span>'. 
     '<span style="position:relative;">'.($in_bottles == TRUE 
? '<a href="/dev/?page_id=7&so=brewery">Available in bottles!</a>' : 
'').'</span>'.  
//PERCENTAGE AND COLOR 
     '<div class="percent-remaining" style="width:'.round(100 * $scale).'px;">'. 
     '<div style="width:'.round(max($percent*100,5) * $scale).'px; height: 20px; background-color: #'.substr("000000".dechex($percent_left_color),-6).';"></div>'. 
     '</div>'. 
     '<div class="percent-number">'.$percent_remaining.'%</div>'. 
     '</div></div>'. 

     ($t == $countnumrows ? '</div><div id="shim"></div><div id="datafieldcontainer">' : '');  

echo $html; 
$t++;  
} 

?>

您需要爲價格添加額外的foreach循環，並使用該循環代替特定的索引。 '''foreach（$ beverage ['MenuItemProductDetail'] ['Prices'] as $ price）''' – arma

嘗試此尺寸。你可以玩的過程中的標記和重構自己的喜好：

新線分別是：

線59-64：

$bottlePrices = $beverage['MenuItemProductDetail']['Prices']; 

$pricesSizesHtml = ""; 
foreach($bottlePrices as $prices){ 
    $pricesSizesHtml .= $prices['DisplayName'] . ": $" . $prices['Price'] . "<br>"; 
}

和線111-112：

//Prices and Sizes 
'<div class="prices-sizes">'.$pricesSizesHtml.'</div>'.

樣本輸出：

Ex Novo 
Eliot IPA 
IPA - Hops (Galaxy, Simcoe, Centennial & Southern Cross) 
ABV: 6.6% | IBU: 65 
BeerAdvocate.com | RateBeer.com 
70% 
Taster: $2 
10oz: $4 
16oz: $6 
32oz: $11 
64oz: $18

這非常有幫助，並且完全符合我的要求，它也非常有意義！有趣的是我現在正在考慮你自己的代碼，「這很容易，我忽略了它！」。 – DigitalSky
