我有以下循环来计算评论和喜欢

.hg/hgrc

在这个循环之后,我有echo function AddCampaignDetails($next=null){ $AccessToken = ACCESS_TOKEN; $url = "https://api.instagram.com/v1/tags/canonfanatic/media/recent?access_token=".$AccessToken; if($url !== null) { $url .= '&max_tag_id=' . $next; } /*//Also Perhaps you should cache the results as the instagram API is slow $cache = './'.sha1($url).'.json'; if(file_exists($cache) && filemtime($cache) > time() - 60*60){ // If a cache file exists, and it is newer than 1 hour, use it $jsonData = json_decode(file_get_contents($cache)); }else{ $jsonData = json_decode((file_get_contents($url))); file_put_contents($cache,json_encode($jsonData)); }*/ $Ch = curl_init(); curl_setopt($Ch, CURLOPT_URL, $url); curl_setopt($Ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($Ch, CURLOPT_TIMEOUT, 20); $Result = curl_exec($Ch); curl_close($Ch); $Result = json_decode($Result); $Data = $Result->data; //echo "<pre>"; print_r($Data); echo "</pre>"; $CommentsSum = 0; $LikesSum = 0; for($i=0; $i<count($Data); $i++){ $CommentsSum += $Data[$i]->comments->count; $LikesSum += $Data[$i]->likes->count; } //echo ' Comments '.$CommentsSum; //echo ' Likes '.$LikesSum; echo "<br />"; if(isset($Result->pagination->next_url) && !empty($Result->pagination->next_url)){ $next = $Result->pagination->next_url; $this->AddCampaignDetails($next); }else{ $NextUrl = ""; die; } return $result; } 变量并获得此输出

$CommentsSum;

现在我想要上面的数字总和183 306 320 42

有什么想法吗?

感谢。

答案 0 :(得分:0)

你的$Data[$i]->comments->count必须是一个数字,它似乎是一个字符串,所以它是合并字符串而不是数学。

如果你真的在每个数字之间有一条新线(就像你在回声中说的那样),那么$Data[$i]->comments->count等于"183\n"

使用例如:

$CommentsSum += intval($Data[$i]->comments->count)
