Question

How do i change a url in a string example :

This is a link <a href="http://google.com.au">http://google.com.au</a>

To something like this

This a warning page link <a href="./warn.php?link=http://google.com.au">http://google.com.au</a>

EDIT:

What i’m trying to do is take a description entered by the end user, They might enter links in the description, i want to change all the links to make them GOTO a warning page, the warning page is ./warn.php?site=link

The string might look like this

This is a awesome description <a href="google.com.au">Google</a> and this another link <a href="http://google.com.au/images">Google images</a>

Ok here’s what i tried:

$descc = mysql_real_escape_string($_POST['description']);

$descc = preg_replace('"\b(http://\S+)"', '<a href="./warn.php?site='.base64_encode(.'$1'.).'">$1</a>', $descc);

Check this, although im not sure if you are really refering to this, just let me know the case then —

$mylink = "http://google.com.au";

This a warning page link <a href="./warn.php?link=<?php echo $mylink ?>">http://google.com.au</a>

EDIT version 1.0

Even it is on description box data you can fetch it via jquery or php like

$mylink = $_GET['desc_name_data']; 

Please be more specific with the problem 🙂

EDIT Version 1.1

Check this and let me know then —

echo preg_replace('(<a href="http://\S+)', '<a href="./warn.php?site='.'google.com.au'.'">google.com.au', $descc);
