Question

我有这样的PHP代码：在

$cinemagiaprepare=file_get_contents("http://www.bing.com/search?q=$numele+$anul+site:https://www.cinemagia.ro/filme/&format=rss&count=1"); 
$cinepatern='#<\/title><link>(https:\/\/www.cinemagia.ro.+?)<\/link><description>#'; 
if (preg_match($cinepatern, $cinemagiaprepare, $matchc)) 
$numeletv1=($matchc[1]); 

那代码搜索：http://www.bing.com/search?q=Walk%20of%20Fame%202017%20site:https://www.cinemagia.ro/filme/&format=rss&count=1

此链接http://www.cinemagia.ro/filme/world-premiere-2009x00-1650809

我的代码只搜索https。我想搜索https和http。

我试试这个正则表达式：

$cinepatern='#<\/title><link>(https.*:\/\/www.cinemagia.ro.+?)<\/link> 

演示：https://regex101.com/r/oNeMMb/1这个表达式选择所有代码。

Answer 1

对于HTTPS可选s，这将是这个

'#</title><link>(https?://www\.cinemagia\.ro.+?)</link><description>#'

Answer 2

用SimpleXML：

$sxe = simplexml_load_file('http://www.bing.com/search?q=$numele+$anul+site:https://www.cinemagia.ro/filme/&format=rss&count=1'); 

echo $sxe->xpath('//link[starts-with(., "http://www.cinemagia.ro") or starts-with(., "https://www.cinemagia.ro")]')[0];
