How to extract hashtag content?

I am trying to extract the content following a hashtag using php.

For example:

$sentence = 'This #Coffee is the #best!!';

How do I get the value 'Coffee' and 'best'? Note, I don't want the exclamation mark after 'best'

Try this one:

|\#(\w*)|

Run in a sentence like

I want to get all #something with #this

It will retrieve "something" and "this". Im assuming that you only wanted the Regex, the function to use is preg_match_all

I'd like better:

preg_match_all('/#([^#]+)#/msiU',$string,$matches);

to handle multiline sentences

A pretty safe catch-all in utf-8/unicode:

preg_match_all('/#([\p{L}\p{Mn}]+)/u',$string,$matches);
var_dump($matches);

Although, if you're not using / expecting exotic characters, this might work equally well and is more readable:

preg_match_all('/#(\w+)/',$string,$matches);
