如何从this JSON字符串中获取标记的所有值并删除所有重复项? 我的代码:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'http://api.tumblr.com/v2/blog/instagram.tumblr.com/posts/text?api_key=myAPIKey',
CURLOPT_USERAGENT => 'cURL Request'
));
$resp = curl_exec($curl);
$response = json_decode($resp,true);
(API密钥是Tumblr提供的公共测试密钥)

在JSON
解码array
:
function uniqueTags($jsonArray)
{
$output = array();
foreach($jsonArray['response']['posts'] as $post)
{
foreach($post['tags'] as $tag)
{
//Iterate over tags in all posts returned
if(!in_array($tag, $output))
{
$output[] = $tag;
}
}
}
return $output;
}

这是你在找什么?
foreach($response['response']['posts'] as $posts ){
if(isset($posts['tags'])){
foreach($posts['tags'] as $tag){
echo $tag . "<br />";
}
}
}

这是一个有趣的:
$tags = array_unique(
call_user_func_array('array_merge',
array_column($response['response']['posts'], 'tags')));
