Check content of text file and if it finds www. it makes a link.

[ztealmax]

Hi is there anyway for a script to read a text file and if it finds some kind of url for example www.phpfreaks.com
it automaticly makes a clickable link of it?

my read text script:
[code]<?PHP require_once("theme.php");?>
<?php
// set file to read
$file = $_GET['text'];
// open file
$fh = fopen($file, 'r') /*or die('Could not open file!')*/;
// read file contents
$data = fread($fh, filesize($file)) /*or die('Could not read file!')*/;
// close file
fclose($fh);
// print file contents


?>
<DIV class="smallblacktext"><pre>
<? echo $data;?></DIV></pre>[/code]

Too many questions today? ;) hehe sorry about that, im full of question  ;D

Try  preg_replace_callback()
http://www.php.net/manual/en/function.preg-replace-callback.php
[code]<?php
function create_link($matches)
{
    //do some work here so a complete url is produced
    //with $matches, etc. 'http://...'
    $link = '<a href="' . $matches . '">' . $matches . '</a>';
    return $link;
}
echo preg_replace_callback(
          "**regular expression here**",
          "create_link", //function name!
          $data); //your variable
?> [/code]
if someone could help you with the actual regular expression to use there, that code should be good to go
