【问题描述】：
我编写了这个 PHP 脚本来回显包含所需内容的 div 的完整示意图。但是，当我运行它时，我只是得到一个空白页。怎么了？
代码：
<?
$url = 'http://socialclub.rockstargames.com/crewapi/the_greeks_360/gtav/photo';
$json1 = utf8_encode(file_get_contents($url));
$photos = json_decode($json1, false);
foreach ($json1 as $pic)
{
echo '<div style="opacity:0.7;width:310px;height:259px;">';
echo '<div style="width:310px;height:174px;display:block;">';
echo '<img src="http://prod.cloud.rockstargames.com/' . $pic->photos->Meta->ImgSrc . '" width="310" height="174" alt=""></img>';
echo '</div><br>';
echo '<div style="opacity:0.7;width:310px;height:52px;display:block;padding:10px;">';
echo '<p>' . $pic->photos->Meta->location . '</p><br>';
echo '<p><a href="http://socialclub.rockstargames.com/member/' . $pic->photos->Meta->nickname . '" target="_blank" alt="">' . $pic->photos->Meta->gamertag . '</a></p><br>';
echo '</div>';
echo '<div style="opacity:0.9;width:310px;height:32px;display:block;padding:8px;margin-bottom:1px;">';
echo '<a href="http://socialclub.rockstargames.com/games/gtav/snapmatic/photo/' . $pic->photos->Meta->Id . '" target="_blank" class="gtavicon-icon_thumbs_up"></a> ' . $pic->photos->Meta->Liked->LikeCount . ' | ';
echo '<a href="http://socialclub.rockstargames.com/games/gtav/snapmatic/photo/' . $pic->photos->Meta->Id . '" target="_blank" class="gtavicon-icon_chat"></a> ' . $pic->photos->Comments->total;
echo '</div>';
echo '</div>';
}
?>
JSON 文件的一个示例是：

【问题讨论】：
-
这有什么“不起作用”的？它有什么作用？不做？有什么错误吗？关于这个问题，您可以向我们提供更多信息吗？你做了什么来尝试调试这个？
-
P.S.你的意思是
foreach ($photos as $pic)？ -
我尝试添加，我没有看到任何我想看到的结果。只是空白，是的，存在一个值。
-
当你得到“空白屏幕”时，打开
error_reporting和display_errors这样你就会知道发生了什么。
