好的，所以我尝试将一些JSON数据输出到PHP页面中。到目前为止，我的PHP代码如下所示：

<?php                                                                    
$string = 
    $string = 
    file_get_contents("https://service.digitalpour.com/BeerDashboard/api/v2/MenuItems/53716a8dfb890c0d68677264/1/Tap?apiKey=53926cc7fb890c0528735cde");

    $json_taps = json_decode($string, true);  


$t=1; 
echo '<div id="taplist-container">'; 

foreach ($json_taps as $beverage) { 

        $item_name = $beverage['MenuItemDisplayDetail']['DisplayName'];
        $producer_name = $beverage['MenuItemProductDetail']['FullProducerList'];
        $beverage_name = $beverage['MenuItemProductDetail']['BeverageNameWithVintage'];
        $beverage_style = $beverage['MenuItemProductDetail']['FullStyleName'];
        $beverage_color = $beverage['MenuItemProductDetail']['Beverage']['StyleColor'];
        $year = $beverage['MenuItemProductDetail']['Year'];
        $beverage_abv = $beverage['MenuItemProductDetail']['Beverage']['Abv'];
        $beverage_ibu = $beverage['MenuItemProductDetail']['Beverage']['Ibu'];

        $rate_beer = $beverage['MenuItemProductDetail']['Beverage']['RateBeerUrl'];

        $price = $beverage['MenuItemProductDetail']['Prices'][0]['Price'];
        $size = $beverage['MenuItemProductDetail']['Prices'][0]['DisplayName'];

        $producer_location = "";
        $producer_url = "";
        switch($beverage_type) {

                break;

                $producer_url = $beverage['MenuItemProductDetail']['Beverage']['SoftDrinkMaker']['Url'];
                break;
        }
        $date_put_on = $beverage['DatePutOn']; 
        $bottle_size = $beverage['MenuItemProductDetail']['Prices'][0]['Size'];   
        $bottle_price = $beverage['MenuItemProductDetail']['Prices'][0]['Price'];

这种产品的产量非常好，但是饮料有多种大小和价格取决于大小。例如，您可以使用上面代码中的链接访问我的JSON提要，但这是饮料的一个片段，它的大小/价格不同：

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
},

因此，我要做的是弄清楚如何用输出的其余数据(参见上面的PHP代码)输出不同的大小和价格，并显示各种饮料的可用大小和价格：

品尝者：$2 10盎司：$4 16盎司：$6 32盎司：$11 64盎司：$18

等等..。

我想出了让它在下面工作的代码：

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

但是，我不知道如何将代码与html输出放在一起：

    $percent_left_color = (max(0,min(255,511 * (1-$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">' : '');

试试这件衣服的尺寸。当然，您可以随意使用标记并根据自己的喜好重构：

新的项目如下：

第59-64行：

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

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

第111-112行：

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

样本输出：

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
