Im struggling here ... is it possible to check for a string pattern
like a valid url in a bigger string. And then return the matching
so if i had a string like : "This is my website it is called www.google.com
and i have made lots of money"
Now how can i match a url in this string.... or any url for that
matter and return it?
In this case it would return "www.google.com".
Thanks in advance.
Re: finding location (start and lengh) of a substring in a bigger string.
You might also need to look at strtok and substr. For example, find the
postion of "www." or "http://: in the string and take the substring of
that. Then take only until the space. Alternatively, you could look at
"explode" and take the one in the array that begins with "www." or
"http://". Of course, if your URL does not begin with "www." or "http://",
then I am not sure how to do it. I would have to investigate that myself,
but you can do that homework as well as I can.
