[PHP] links extract from a string

[Syed Ghouse]

Hi all

i m doing a project in which i m displaying the statistics of

clickcounts of links send thru a message.

For that i have to extract the links from the message string given by user.

So pls tell me how to get the url/links from a string (or) To track clicks of all 
outgoing links embedded in the message string

Thanks
