I am having problems grabbing some text using preg_replace() in php. I am just trying to remove all text that starts with a http|https|www up until the first whitespace character. I am currently using: (http|https|www)\S+ as my regex in preg_replace(). However I am getting this error when running the code: Warning: preg_replace(): Unknown modifier '\' I can use this same regex in a text editor, e.g. Sublime Text 2 with no problem. Any ideas why I am getting this error? Is there another way to grab the text I am looking for with a regex?
Thanks for any help.
