Need help understanding how to turn input url into clickable link

[codeboy89]

Alright, I found the following function online.

 

function HyperlinkText($text) {
return ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]", "<a href=\"\\">\</a>", $text);
}

 

Can anyone explain to me how I would use this function to turn a url into a clickable link. I want to use it on a input field named "bull". Here is my code currently that takes data and submits it to an XML file to be viewed.

 

$file_name = "bb.xml";
$file_act = fopen($file_name, "r+");
$lock = flock($file_act, LOCK_EX);
$file_read = fread($file_act, filesize($file_name));

$date = date ("j M Y");
$post = "<bb>\n<p>$name  $date<br />$bull</p>\n</bb>\n";

$post = stripslashes($post);
fwrite($file_act, "$post");
fclose($file_act);

 

I am not sure how to incorporate this function. I would really appreciate any help.

Well it seems fairly obvious that you will want to try and call your HyperlinkText() function.

 

How about:

 

$post = HyperlinkText(stripslashes($post));

When you call it you wont get anything. replace it with:

ereg_replace("(^| |.)(www([.]?[a-zA-Z0-9_/-])*)", "<a href=\"http://\\2\">\\2</a>", $text)

 

Your input should be

www.domain.com

or

domain.com

I added the function, and called it the way gizmola has shown above. It does not work. Nothing updates at all.

I forgot to mention I want this to find and make any urls into links, that is what the original ereg_replace is supposed to do. It is not a url only input field.
