Action()类的操作:
public function curl_get($url){
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url); //设置提交的url
curl_setopt($curl, CURLOPT_TIMEOUT, 5);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //参数为1表示传输数据，为0表示直接输出显示。
curl_setopt($curl, CURLOPT_HEADER, 0); //参数为0表示不带头文件，为1表示带头文件
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); //如果接口URL是https的,我们将其设为不验证,如果不是https的接口,这句可以不用加
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
$output = curl_exec($curl); //执行命令
curl_close($curl);
return $output;
}
PATH_RSSHUB_APP：在config.php文件下的配置：
define('PATH_RSSHUB_APP','https://rsshub.app');
Controller的操作：正则获取解析的数据这些是网上找的，忘在哪篇文章了
//订阅源数据显示
public function show(){
$act = new Action();
$url = PATH_RSSHUB_APP.'/readhub/category/news';//Readhub
$html = $act ->curl_get($url); //获取rss源的数据
$item = '#<item>(.*)</item>#isU'; //采集的正则（所有内容）
preg_match_all($item,$html, $html2); //正则匹配
$html3 = array();
//处理数组 三维变二维
foreach($html2 as $k2=>$v2){$html3 = $v2;}
//正则采集
$pattern_tle = '#<title>(.*)</title>#isU'; //1、标题
$pattern_desp = '#<description>(.*)</description>#isU'; //2、内容
$pattern_pubdate = '#<pubDate>(.*)</pubDate>#isU'; //3、日期
$pattern_desp2 = '#阅读：([1-9]\d*+).*</description>#isU'; //4、阅读量
$pattern_link = '#<link>(.*)</link>#isU'; //5、原文链接

$firstshow = strpos($str,"]"); //字符串中第一次出现的位置
$getstr = substr($str,$lastshow,$firstshow - $lastshow); //substr 截取字符串
