如何使用正则表达式获取多个URL http和https？

Question

http:\/\/embed.(.*).com\/\?id=([0-9]+)

$userAgent  = array('http' => array('user_agent' => 'Mozilla/5.0 (Linux; U; Android 4.0; en-us; GT-I9300 Build/IMM76D)'));

is there anyway to get both http and https with the above code?

Answer 1

Add an optional pattern s? ( s will match an s and ? will make the regex engine match it one or zero times):

https?:\/\/embed\.(.*)\.com\/\?id=([0-9]+)
    ^^ 

I also think you forgot to escape the dots after embed and before com . You also might want to replace (.*) with ([^\\/]*) to avoid overflowing across / separated URL sections, so consider using

https?:\/\/embed\.([^\/]*)\.com\/\?id=([0-9]+)
