我正在处理我的代码以获取数据以将其输出为HTML。我在PHP之外的html源中显示数据时遇到问题，因为我收到了一个错误：
警告：第150行的/home/username/public_html/check_score.php中为foreach（）提供的参数无效
第150行：
foreach($score->rules AS $rule) {
echo '<div name="test-row" style="margin-top:-1px">
<div name="description" style="float: left; width:470px;">' . $rule->description . '</div>';
echo '<div name="scores" style="float: right">' . $rule->score . '</div>';
echo '</div><br><hr>';
}
这是完整的代码：
<?php
if(isset($_POST['btn1']))
{
sleep(1);
$ch = curl_init('http://example.com/check_score');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
$message = "hey chris";
$header = "Delivered-To: example@gmail.com

the long list of the header goes here...
Hey rob,
How you doing?";
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('email' => $header, 'options'=>'long')));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
$response = curl_exec($ch);
$score = json_decode($response);
?>

我已经在显示的PHP中检查了$ score的结果：
stdClass Object ( [success] => 1 [score] => 0.2 [rules] => Array ( [0] =>
stdClass Object ( [score] => 0.1 [description] => Message has a DKIM or DK
signature, not necessarily valid ) [1] => stdClass Object ( [score] => 0.1
[description] => DKIM or DK signature exists, but is not valid ) ) [report]
=> pts rule description ---- ---------------------- ------------------------
-------------------------- 0.1 DKIM_SIGNED Message has a DKIM or DK
signature, not necessarily valid 0.1 DKIM_INVALID DKIM or DK signature
exists, but is not valid )
将$ score放入HTML中后，结果将显示为空。
昨天工作正常，但今天在这里不工作。当我能够毫无问题地使用PHP提取数据时，我真的不理解为什么变量$score在HTML中显示为空。我试图在Google上找到答案，但在任何地方都找不到。
您能帮我如何使用变量$score在HTML中显示数据吗？
谢谢。
答案 0 :(得分：2)
我刚刚注意到这里的东西。我不确定是否可以解决该错误，但这可能是一个起点。循环中的第一条回显行没有尾随分号：
foreach($score->rules AS $rule) {
echo '<div name="test-row" style="margin-top:-1px">
<div name="description" style="float: left; width:470px;">' . $rule->description . '</div>';
echo '<div name="scores" style="float: right">' . $rule->score . '</div>';
echo '</div><br><hr>';
}
试一下：
foreach($score->rules AS $rule) {
echo '<div name="test-row" style="margin-top:-1px">;
<div name="description" style="float: left; width:470px;">' . $rule->description . '</div>';
echo '<div name="scores" style="float: right">' . $rule->score . '</div>';
echo '</div><br><hr>';
}
答案 1 :(得分：0)
您的$score变量会在表单提交时填写，因此您不能在模式视图中的表单发布后允许$score变量。
您可以尝试使用以下代码代替代码吗？

我的答案已更改为正确的解决方案。
curl.php;
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST' && $_POST['submit'])
{
sleep(1);
$ch = curl_init('http://example.com/check_score');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
$message = "hey chris";

我无法测试上述代码，但这必须可行。
