非对象的 PHP 属性 - URL 中的变量

Question

我在尝试将动态变量应用于 URL 时遇到错误，它本身也被设置为变量，$sURL。
例如，如果我将".$prNameUrl."更改为关键字 CATS，它可以正常工作。但是一旦我输入一个变量，我就会收到错误：注意：尝试获取非对象的属性

$prNameUrl = $v->product_name.' '.$v->product_category.' '.$v->product_format;

$prNameUrlTwo = 'https://api.cognitive.microsoft.com/bing/v7.0/images/search?q='.$prNameUrl.'&count=4&mkt=en-US';
$sURL = $prNameUrlTwo;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: multipart/form-data',
    'Ocp-Apim-Subscription-Key: xxxxxxxxx'
));
$contents = curl_exec($ch);
$myContents = json_decode($contents);
if(count($myContents->value) > 0) {
    foreach ($myContents->value as $imageContent) {
        echo "<a href='{$imageContent->webSearchUrl}'><img src='{$imageContent->thumbnailUrl}' width='290' height='200' /></a>";
    }
}

我已经解决了"urlencode"的问题。

$sURL = $WebSearchURL . urlencode( ''' . $prNameUrl . ''') . '&count=4&mkt=en-US';
