使用PHP获取URL的一部分

Question

I have a site and I would need to get one pages URL with PHP. The URL might be something www.mydomain.com/thestringineed/ or it can www.mydomain.com/thestringineed?data=1 or it can be www.mydomain.com/ss/thestringineed

So it's always the last string but I dont want to get anything after ?

You will use the parse_url function, then look at the path portion of the return. like this:

$url='www.mydomain.com/thestringineed?data=1';
$components=parse_url($url);

//$mystring= end(explode('/',$components['path']));

// I realized after this answer had sat here for about 3 years that there was 
//a mistake in the above line
// It would only give the last directory, so if there were extra directories in the path, it would fail. Here's the solution:
$mystring=str_replace( reset(explode('/',$components['path'])),'',$components['path']); //This is to remove the domain from the beginning of the path.

// In my testing, I found that if the scheme (http://, https://, ...) is present, the path does not include 
//the domain. (it's available on it's own as ['host']) In that case it's just  
// $mystring=$components['path']);
