regex - PHP: URL detection (regexp) includes line breaks -

I want to get a text in the form of input that output.

My draft is as follows:

  function automatically links ($ text) {return preg_replace ('/ https :? / \ / [\ S] + / I, '& Lt; a href = "\ 0" & gt; \ 0 & lt; / a & gt;', $ text); }  

But it does not work properly.

For input text in which ...

  http: //www.google.de/  

... me The following output is available:

  & lt; A href = "http://www.google.de/ 
 & gt; Http: //www.google.de/< Br & lt; / A & gt; / & Gt;  

Why does it include line breaks? How can I limit it to the real URL?

Thanks in advance!

OK, & lt; is not a white space character, so you can exclude it from your set of approved characters:

  preg_replace ('/ https?: \ / \ / \ ^ & Lt;] + / i ',' & lt; a href = "\ 0" & gt; \ 0 & lt; / a & gt; ', $ text);
