Tokenising My Blog - Need image to seperate variable...

[gaza165]

I am retrieving my blog from the database, at the moment i am search for images, youtube videos and a links.

 

As you can see from the code I am using preg_match and preg_replace to search for their particular patterns.

 

I am then using str_replace to replace the values on output with their appropriate values. So say the image links are posted into the database like....

 

http://www.domain.com/image.jpg

 

i then replace that with %TOKEN0%

 

once this is all done i echo out

 

echo $string;

 

Basically what i want to do is be able to echo out the image contained in the $string as a seperate item.... soo i can do...

 

echo $string

 

and then

 

echo $image

 

Hope someone can help.... thanks...
