Regex to parse megavideo URL
I'm trying to write a regex to parse a this url for a php script:
http://www.megavideo.com/v/B4PZHP0Nb2e8a877f8378e778446318596415780
to get this: B4PZHP0N
Can someone help? Th开发者_运维知识库anks in advance.
Since you're in PHP, just use parse_url
and substr
:
$mega = 'http://www.megavideo.com/v/B4PZHP0Nb2e8a877f8378e778446318596415780';
$want = substr(parse_url($mega, PHP_URL_PATH), 3, 8);
Demo: http://ideone.com/f3viH
Try this regex:
/^http:\/\/www\.megavideo\.com\/v\/(.{8}).*$/
(The error has been corrected)
Also see my ideone or my jsfiddle.
/([^:.\/]+)[a-f0-9]{32}/
So if it matches, B4PZHP0N is in capture buffer 1, ie: $1
I have done something similar but a bit more generic. so the id can come either after /v/, ?v= or &v=
$url = 'http://www.megavideo.com/v/B4PZHP0Nb2e8a877f8378e778446318596415780';
foreach (array('/v/', '?v=', '&v=') as $k)
{
$pos = strpos($url, $k);
if ($pos>0)
{
$pos += strlen($k);
break;
}
}
if (!$pos)
die("not found");
$id = substr($url, $pos, 8);
die($id);
