php regular expression string replace

Question

I have a string like that as json response for a script:

"Lorem ipsum dolor sit amet, consectetur adipiscing elit, HTTP://unknown/string/in/unknown/place/ , sed do eiusmod tempor incididunt ut labore et dolore magna aliqua"

is there a way to replace with an empty string using regular expression and php preg_replace?

I'm not familiar with regular expression, could you just provide an example? I basically need to remove the substring starting with 'http' and finishing with a space, IF possible.

thanks

Something like

preg_replace("/HTTP\S+\s,/", "","Lorem ipsum dolor sit amet, consectetur adipiscing elit, HTTP://unknown/string/in/unknown/place/ , sed do eiusmod tempor incididunt ut labore et dolore magna aliqua" );

Will give output as

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua

Regex /HTTP\S+\s,/

\S matches anything other than a space
\s matches a space

Regex Demo

EDIT

A better solution like

/HTTP\S+(\s,|$)/

So that the link can apear anywhere in the string even at the end.

Example

preg_replace("/HTTP\S+(\s,|$)/", "","Lorem ipsum dolor sit amet, consectetur adipiscing elit, HTTP://unknown/string/in/unknown/place/" );
=> Lorem ipsum dolor sit amet, consectetur adipiscing elit,

just another thing: if my unknown url is in the end of the main string without space and slash in the end, there is a way to match it? If not I would use string split, but if there is a way it would be better so that I can match all possibilities in one function call: "Lorem ipsum dolor sit amet, consectetur adipiscing elit, t.co/LjAezrssLM" if this is not possibile just thanks again!
