PHP - Convert Text To Link Which Retrieve From Database

Hello. I have a bit of a problem. When I fetch the link field from the database.i don't see an actual link on the page.  One more thing, what type of field should I use to store the link in the database? Probably there is where I went wrong. All help is 

Hi Support,

I have a form, where it collects user description input. I can collect the inputs and store it with newline. The issue is - how to collect the http link to actual hyperlink ref during display.  The following is my code:

<textarea name="description" cols="50" rows="10" id="description"><?php echo str_replace("<br>", "\n", $description);?></textarea></td>

For example, User input:

Hi, Check it out - http://www.google.com/

I would like to display google link as href so that Viewers can click the link and go to the page. Right now, it is not href and user need to copy the link to new tabs or pages and then it can come.

Thanks for your help.
Regards,
Ahsan

Hello all! I am somewhat new to PHP and SQL, but I think I have a basic understanding of how the language works. I have read through a million different websites and forums, and have tried a million different ways but am just not getting anywhere!

This is what I am trying to do... I have a text link that I want to click through to an outside URL from my website. This outside URL was already entered into an SQL database, and I just cant seem to get the text link to bring up the outside URL from the database. This is what I have so far...

1.) My webpage that I am working on is www.mywebsite.com/articles.php
2.) I want the text "Read more..." on this webpage to click through to an outside URL, like "http://www.google.com", which was already entered into an SQL database under the title of "article_link" in a new window
3.) So I would like for "Read more..." to click through the outside URL that was entered into "article_link" in the database

Code: [Select]
<?php
echo <p><a href="\' . $article_link . '\" target="_blank">Read more...</a></p>;
?>
Nothing I have tried has worked so far, nothing clicks through to the outside URL in the "article_link" entry from the database. Sorry if I am being redundant, I have been at this all day! Please help and thank you in advance!!
