JavaScript
Method String.prototype property invoked parseURL. When called on a String the regular expression finds any case of a URL and will enclose the URL with a HTML anchor tag.
<head> 
String.prototype.parseURL = function()
{
return this.replace(/[A-Za-z]+:\/\/[A-Za-z0-9-_]+\.[A-Za-z0-9-_:%&\?\/.=]+/, function(url) {
return url.link(url);
});
};
</head> 

index.php
Here we applying the parseURL() method to text variable called posted update contains a URL. But in database the update does not contain any anchor HTML tag.

<body> 

<form action="" method="post">
<span class="what">What are you doing?</span>
<textarea  =""  cols="55" id="update" maxlength="145" name="update" rows="3"></textarea>
<input type="submit" value=" Update "  class="update_button" />
</form>


<?php

include("dbconfig.php");
$sql="select * from updates order by ms_id desc";
$result = mysql_query($sql);
while($row=mysql_fetch_array($result))
{
$message=stripslashes($row["message"]);
?>
<tr>
<td>
//---------------------------------------------------------------

<script type="text/javascript">
var test = "<?php echo $message; ?>";// Variable text = Updates from the database
document.write(test.parseURL());
</script>


//---------------------------------------------------------------
</td>
<td>
<a href="#" id="<?php echo $row["ms_id"]; ?>" class="delbutton"><img src="trash.png" alt="delete"/></a> </td></tr>
<?php
}
?>

</body>
