How to seperate Model Numbers from a string

[rahulephp]

Can anyone please let me know how to separate Model Numbers from a string

For Ex Titles:
1) Sony DCSW380B 14MP Camera
2) Casio 10MP Camera EX-Z3/3
3) Panasonic Lumix Camera DMC-G1 12MP

Output would be:
For 1) "DCSW380B 14MP" OR ""DCSW380B"
For 2) "10MP EX-Z3/3" OR "EX-Z3/3"
For 3) "DMC-G1 12MP" OR "DMC-G1"

Criteria:
1) All letters of model number are CAPITAL
2) It may include alphabets, numbers or special symbol like "/", "-"
3) Model numbers can be anywhere in the title (not a specific position like 2nd in array on explode)

Not sure if i need to use preg_match function.

Please assist. Thanks in advance

If the products are consistent you could build a list of keywords to be removed. For example you have list that includes sony, panasonic, casio, camera etc. Then run your strings through a function to remove any keywords.

Just a thought though... there maybe a more elegant solution out there.

I got the solutions in another way,
Here it is:

<?php
$titles = Array('Sony DCSW380B 14MP Camera', 'Casio 10MP Camera EX-Z3/3', 'Panasonic Lumix Camera DMC-G1 12MP');

foreach($titles as $item)
{
    if(preg_match_all('/\b([A-Z0-9\/\-\+]+)\b/', $item, $tmp))
        print implode('||', $tmp[1]).'<br />';
}

?>

The output is separated by "||" in case if i need it in future.
