我对编码非常陌生。
我正在使用PHP从API获取JSON响应。 JSON响应由标题和指向Web页面的URL组成。样本JSON响应位于页面底部。
如何使用PHP将此JSON数据中的每个项目写入body标签中的HTML页面？我想创建HTML“ a”标签，其中文本是每个项目的JSON名称值，而href是JSON URL值。
使用PHP从API获得JSON数据后，JSON数据在哪里结束，然后如何使用PHP访问并格式化它？我正在使用PHP保留我的API访问密钥服务器端，以便客户端看不到它。这是我的代码：
<?php
$accessKey = "12345678";
$endpoint = '*Imaginary API endpoint*';
$term = 'hi';
function APIResponse ($url, $key, $query) {
$headers = "Ocp-Apim-Subscription-Key: $key\r\n";
$options = array ('http' => array (
'header' => $headers,
'method' => 'GET'));
$context = stream_context_create($options);
$result = file_get_contents($url . "?q=" . urlencode($query), false, $context);
$headers = array();
foreach ($http_response_header as $k => $v) {
$h = explode(":", $v, 2);
if (isset($h[1]))
if (preg_match("/^APIs-/", $h[0]) || preg_match("/^X-MSEdge-/", $h[0]))
$headers[trim($h[0])] = trim($h[1]);
}
return array($headers, $result);
}
if (strlen($accessKey) == 8) {
print "Searching the Web for: " . $term . "\n";
list($headers, $json) = APIResponse($endpoint, $accessKey, $term);
print "\nRelevant Headers:\n\n";
foreach ($headers as $k => $v) {
print $k . ": " . $v . "\n";
}
print "\nJSON Response:\n\n";
echo json_encode(json_decode($json), JSON_PRETTY_PRINT);
} else {
print("Invalid API subscription key!\n");
print("Please paste yours into the source code.\n");
}
?>

答案 0 :(得分：0)
要打印数据，可以使用：
$result = json_decode ( $json, true);
foreach ( $result["webPages"]["value"] as $data)
{
echo "<a href=\"" . urlencode ( $data["id"]) . "\">" . $data["name"] . "</a>\n";
}
我喜欢使用json_decode()方法返回数组而不是对象，并使用 true 作为第二个参数，但是如果您愿意，也可以将其用作对象。

在javascript部分中尝试一下...
document.body.onload = addLink;
function addLink () {
// FIRST method : Embedding php in javascripts
<?php foreach(json_encode($json)->webPages->value as $value) { ?>
// Create a new markup
var newContent = $('<a href="<?php echo $value->url ?>"><?php echo $value->id ?></a>');
// And add the text node to your div by it's class / id
$('.link').appendChild(newContent);
<?php } ?>
//////////////
// ...OR... //
//////////////
// SECOND method : Pass php variable (in this case it's JSON object) into javascripts
var json = <? echo json_encode($json)->webPages->value ?>;
json.forEach(function(value){
// Create a new markup
var newContent = $('<a href="' + value.url + '">' + value.id + '</a>');
// And add the text node to your div by it's class / id
$('.link').appendChild(newContent);
});
}
希望它能正常工作，因为我不是每天的php程序员。
