thank you. https: are being ignored and replaced by http: which is not good. Some fix for that ? Also, could you please wrap this into a function text_to_link() ? Thank would be great!

Thank you.

Although DaveBaldwin mentioned it in the other question, conspicuous by its absence on this page is any mention of this function:
http://php.net/manual/en/function.urlencode.php

Please read the description of that function.  You were lucky enough to get away without using it in the other question because you gave us an incomplete test data set.  It only had URL strings that did not contain spaces or special characters.  The most important thing a programmer can have is a robust test data set.

Please use the code snippet and re-post the data string you want us to operate on.  I will try to use what is posted above, but the way EE creates links from client text may cause troubles.  The code snippet is a much more dependable way to post code.

Thanks, ~Ray

Given what we have to work with, this is what I would do.  You can use your browser's view source to see the completed links.  It should be fairly easy for you to encapsulate this code into a function or class method.

A few notes...

In the fourth URL you will see TE+ST.  The plus sign has a special meaning in a URL.  It is decoded into a blank.  That may or may not be what you want.  Line 10.

The regular expression is designed to work on a single, trimmed, line of text.  Note the use of trim() in the function call to preg_match() on line 32.

We use urlencode() on the part of the URL that needs to be encoded (line 35).

We use htmlentities() to escape the part of the output that might be potentially dangerous if we wrote it to the browser in clear text.  Generally speaking you want to escape any browser output that might have come from an external source like a data base, a cookie, or client input (line 38).

At this point we have an array with the correctly encoded URLs in the key positions and the escaped link text in the corresponding value positions.  We construct the links in the $new array by combining HTML tags, the URLs, and the link text (line 42).

Hope that helps, ~Ray

Hi Ray,

This is the best solution I've tried, it work perfect with my test data a all type of links I tried. Also your explanation was super!

Just one thing and please accept my apologize because I forgot something on the test data that I had included on my other question.

See my exact test data type attached. Would be possible to allow single text line?

Thank you for the great support!

Not sure I understand the question.  What would you want to do with a line that said "filesocinc" ?

I just want to ignore "filesonic" or the other non url string.

I tried my last attached test data and I got:
Notice:  Undefined offset: 1 in Untitled-1.php on line 37

I hope it is clear now.

Thank you for your help!

The result I mean would look like this:

Thank you.

mine does as you said, but rays is best solution.

you need to be specific instead of moving the goal post

Awesome solution as usual! Thank you.
