reddit_使用PHP和JSON获取URL的Reddit分数-白红宇

Since we can see Digg turning more into a funny-pic-and-vid site each day, I've turned my attention to Reddit. Reddit just seems more controlled and programmer-friendly. Since I have respect for Reddit I thought I'd put together a quick tutorial on how you can retrieve a URL's Reddit score using PHP.

由于我们每天都能看到Digg变成一个有趣的生动视频网站，因此我将注意力转向Reddit。 Reddit似乎更具控制性且对程序员更友好。由于我尊重Reddit，所以我想整理一个快速教程，介绍如何使用PHP检索URL的Reddit分数。

PHP (The PHP)


    "; //21	echo "Downs: $downs
"; //8	echo "Score:  $score
"; //13	/* utility function:  go get it! */	function get_url($url) {		$ch = curl_init();		curl_setopt($ch,CURLOPT_URL,$url);		curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);		curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,1);		$content = curl_exec($ch);		curl_close($ch);		return $content;	}?>

Parsing the JSON is simple using json_encode with the value of true to make turn the JSON into an associate array. My example shows how you can grab the number of "ups" and "downs" -- not just the score. As with every API/web service, I highly recommend caching the result of your request.

使用json_encode和true值来解析JSON很简单，可以将JSON转换为关联数组。我的示例显示了如何获取“上升”和“下降”的数量-而不仅仅是分数。与每个API / Web服务一样，我强烈建议您缓存请求的结果。
