如何在回聲後插入foreach？

Question

這可能是一個愚蠢的問題，所以請接受我的道歉。

我寫了一個代碼片段，用於列出餐館的wordpress網站。您輸入場地的instagram ID（如果有的話），並顯示他們上傳的最新instagram照片。如果instagram id值留空，我希望它不迴應任何內容。我已經編寫了代碼，並且它適用於帶有instagram id的地方，但由於我無法在echo部分中找到最後一段代碼（以foreach開頭），所以即使id爲空也會嘗試顯示它我得到了一個「爲foreach（）提供的無效參數」錯誤。你能幫我一把，這樣我就可以將這段代碼包含在echo部分中，這樣當id爲空時它就不會調用那段代碼了嗎？首先十分感謝。

<?php 
if ($instagramid) { 
echo "

也許就像有人說的，你需要把你的循環中，如果statment這樣

<?php 
if ($instagramid) { 

// Your old code is here "your echo" 
// but before end of if statment, and after echo"" put loop 

foreach ($result->data as $fotos){ ?> 
    <!-- Renders images. @Options (thumbnail,low_resoulution, high_resolution) --> 
    <span style="font-size: 12px; float:left; margin:5px 0 2px 10px;"> 
    <a target="_blank" class="group" rel="group1" href="<?= $fotos->link ?>"> 
    <img width="90" src="<?= $fotos->images->thumbnail->url ?>"></a> 
    <span style="font-weight:bold; float:left;"></span> 
    <span style="float:right;"><span style="color:red; font-weight:bolder;">❤ </span><?= $fotos->likes->count ?></span> 
    </span><?php } //Biter ?> 
} 
else { 
    echo ""; 
} 
?>
